[RE-wrenches] SolarEdge optimizers require amp deration?

[Mick Abraham via RE-wrenches]

Hi, Wrench List colleagues~ I have a minor dispute with a technician at one
of the solar superstores. He says the amp rating on SolarEdge optimizers
needs a 25% "safety factor".

SolarEdge's spec sheet says "Maximum Output Current" for model S500 is 15
amps. I'm not sure if the technician would take 25% off the 15a or if he
boosts the Isc amps (on the PV datasheet) by 25%. In one case, his
allowable short circuit amps (from the datasheet) would be 11.25a and in
the other case it's 12a.

If he's right, this "500 watt optimizer" could only process 500 watts in an
unusual combination of Vmp and Imp. I know the PV's open circuit voltage
should be calculated higher based on the lowest possible cell temperature,
but I can't find any SolarEdge reference materials that address the
amperage. I checked the SolarEdge videos, installation documents, and I
even spent time in voicemail perdition.  Their design tool at
designer.solaredge.com did suggest the S500 optimizer after I entered all
the parameters for my preferred module.

Nothing else from SolarEdge so far...so it's Wrenchie time. It would be
especially helpful if someone has a white paper or other document to clear
this up. I'm pretty sure the technician wrong on this point, but I'd like
to offer more than just my opinion. BTW, the PV's that I'd like to use are
450 watt monocrystalline, two strings of 54 cells and 14.55 amps short
circuit current. The relatively low cell count does translate into higher
amps per rated watt compared to a module with more cells in series.

Thanks as always; the Wrench List is the Bomb!

Re: [RE-wrenches] SolarEdge Car Charger

[david quattro via RE-wrenches]

I haven’t installed a Solaredge in years so my info might not be up to
date, but I remember that the EV Charger units couldn’t be commissioned
without an active internet connection.  The early models had high failure
rate, but that was within the first year or two that they offered the EV
Charger/inverter. I hope they would have fixed those bugs by now.

I have never installed the SolarEdge car charger, and even though it seems

[RE-wrenches] SolarEdge and Schneider Conext

[Howie Michaelson via RE-wrenches]

Hi all,
Had anyone successfully established communications between a SolarEdge
single phase inverter and a Schneider Gateway? I have a client with a
battery backup system which included a dual stack of XW pros and 2 AC
coupled SolarEdge inverters. He would really like to be able to use one
monitoring site to see all the equipment. Right now, the SolarEdge
inverters are invisible on the Insight cloud or local sites, with net
production magically appearing from the house loads. Any ideas or there?
Thanks,
Howie

Re: [RE-wrenches] SolarEdge Monitoring Access

[Mac Lewis]

Hello Wrenches,

I don't have a ton of SolarEdge experience, but I found that they seem
pretty good at chat support.  Fairly fast and effective the few times I've
done it.  Hopefully they could resolve this issue using this method.

You can sign up as an installer and then log in here.
https://www.solaredge.com/us/service/support/kb?mode=installer

It will bring up a chat box option.

I may also just start a tech support case and see where that leads.

Good Luck

[RE-wrenches] Solaredge/LG Troubleshooting

[Jon Siegenthaler]

 Hi Michael,
I've been there with Solaredge and LG so many times I just call them after
it's all installed and make them walk me through the commissioning process.
Yes, we are solar professionals and yes we can read and follow instructions
BUT, I've sent back fully working inverters after tech support couldn't
figure out an issue they programmed.
You'll have to sit on call waiting for a couple of hours but DO NOT let
them hang up until it's working. While I cannot remember ever seeing this
error code, and as you may be suspecting it could do with the; battery
wiring either comm or power, the auto transformer either comm or power, or
the inverter comm or power. If the owner can get really clear photos and if
everything is easy to follow (like different colored comm wires rather than
all black wires) then you might be able to see if that is the problem. It
could be a bad inverter but it could just be a simple thing that tech
support can change remotely.
Side note, if folks are waiting a year for interconnection but passed local
inspections, can't you start out as zero export and change once the utility
gives PTO? Maybe not but it's worth asking.

Jon

Wrenches,

I received a call from a person who is having issues with his Solaredge/LG
system. He’s got a SE7600A-US, StoreEdge connection unit, autotransformer, and
LG battery. I’ve never laid hands on SE or LG equipment and could use some
guidance here. He’s located several hours from me, and I’m the only Solar Bozo
around>
His Words:

Happy Saturday Michael, thanks again for taking an interest in my solar
situation.  In June 2020 my 9.920 KW (15,752 kWh estimated production) solar
system was installed by now bankrupt "Empire Solar".  Thirty-one (31) 320W
panels were installed on my roof. My system included a battery back-up system
which utilizes an LG Li-Ion RESU10H battery (model #R15563P3SSEG).

Unfortunately, more than a year passed after installation for a net metering
agreement (NME) with Pacific Power to be put in place. Pacific Power installed
a new compatible meter on my home the same week I learned Empire Solar filed
for bankruptcy.  Empire sent me an email with easy-to-follow instructions for
turning my system on. I followed the very simple instructions with zero
results. Pacific Power since confirmed my system is not generating any power.


Currently, my "Solar Edge" inverter displays error code "2x1A - Faulty AC
Relay".  The inverter cycles through a 5-minute "wake-up" routine in which it
counts down from 300 before it displays the aforementioned error code, then
begins the wake-up countdown again and repeats this cycle endlessly until I
power off the LG battery.

Thanks everyone

[RE-wrenches] SolarEdge Energy Hub

[Jason Szumlanski]

A homeowner reached out to me with an issue that I am not familiar with
because I don't do a lot of work on SolarEdge. She has an Energy Hub and is
disappointed that her contractor sold her a system with "future generator
support firmware upgrade" promised. From what I read, this upgrade never
came or still has not come.

Does anyone have any insight on whether generator support is available or
still in the works?

She's in Grass Valley, CA if anyone wants to contact me off-list that can
maybe help her.

Re: [RE-wrenches] SolarEdge inverter blowing fuses

[Jason Szumlanski]

Good feedback. I'll note that we haven't seen any issues with the Eaton
60A, but we decided to go with Square D because it is robust and cost
effective.

Hi All,
I thought I would follow up to report that I swapped out the old GE 60A
switch with a SQD one, and there have been no blown fuses since!

 It's just a garbage product. We switched to Square D for 60A D222NRB
 fusible disconnects and are also using their 100A circuit breaker
 enclosures which are cost effective. The D223NRB is also a good fusible
 disconnect, but pricey.

 GE gave us some nonsense answer that it's General Duty and not designed
 for continuous high power. Even 40A combined Enphase systems will blow a
 60A fuse.

 What you will find is the fuse will blow on one side and then
 replacements will blow at decreasing intervals until it blows daily. Our
 experience is the left side (of the 2-pole)  is far more problematic for
 some odd reason. It's not the fuse brand either.

 I believe the design fault is how the blades only hit a single contact
 on one side when they close. The Square D alternative has the blade
 slipping between two contacts.

 Sadly we have had to replace so many of these and most are supply side
 interconnections, which make it tricky and expensive.

Re: [RE-wrenches] SolarEdge inverter blowing fuses

[Jason Szumlanski]

Trust me when I tell you that all of the line side conductors and taps are
likely fine. It is unequivocally the switch contacts that are the issue.
That said, I usually replace the conductors when there is any indication of
overheating near the terminals. I have seen discolored copper, but it never
gets bad enough to melt insulation.

It is always the left fuse! Thanks all for the pointers. I'll double check
the monitoring, but am thinking that I will be replacing the switch with a
SQD, and replacing the taps and AC wires as well while I'm at it.

 Hi All,

 I am servicing a system that keeps blowing fuses on the AC side,
 although it
  appears that everything is sized correctly. It is a SolarEdge
 SE11400A-US inverter.
  Max continuous output current is 47.5A x 1.25 = 59.4A. There is a GE
 TG3222R
  60A AC disconnect, and it is wired up with #6 THHN wire. The terminals
 were tight
  and there was no evidence of arcing or burning in the past. This is
 indoors, and not
  exposed to sunlight. No extra conductors are in the conduit.

 But they say that they need to replace a fuse roughly once per month.
 Has anyone
  seen this before? Could there be some kind of fault in the inverter
 itself that
  occasionally induces extra current? Is there any way to tweak the
 settings so that it
  actually produces a bit more than 11.4kw? I appreciate your thoughts.

 Cheers,
 Dave

Re: [RE-wrenches] SolarEdge inverter blowing fuses

[Jason Szumlanski]

I should also mention that it has nothing to do with ambient heat. This has
occured in all seasons and with disconnects in direct sunlight on a south
wall and disconnects in air conditioned garages.

It's just a garbage product. We switched to Square D for 60A D222NRB
fusible disconnects and are also using their 100A circuit breaker
enclosures which are cost effective. The D223NRB is also a good fusible
disconnect, but pricey.

Re: [RE-wrenches] SolarEdge inverter blowing fuses

[Jason Szumlanski]

It's the disconnect. We had dozens of this subpar disconnect design fail on
Enphase systems. The 2 Pole has the same issue.

GE gave us some nonsense answer that it's General Duty and not designed for
continuous high power. Even 40A combined Enphase systems will blow a 60A
fuse.

What you will find is the fuse will blow on one side and then replacements
will blow at decreasing intervals until it blows daily. Our experience is
the left side (of the 2-pole)  is far more problematic for some odd reason.
It's not the fuse brand either.

I believe the design fault is how the blades only hit a single contact on
one side when they close. The Square D alternative has the blade slipping
between two contacts.

Sadly we have had to replace so many of these and most are supply side
interconnections, which make it tricky and expensive.

Re: [RE-wrenches] SolarEdge inverter blowing fuses

[Howie Michaelson]

I would think that if there is an internet connection that a call to tech
support would make things quicker, since they have access to internal error
codes which usually give a pretty good indication of what the problem is,
or at least usually help direct where your troubleshooting efforts are best
directed...

Re: [RE-wrenches] SolarEdge inverter blowing fuses

[August Goers]

I would definitely check the insulation on the AC-side wiring as Lloyd
mentioned. Sometimes small faults don't show up until there is moisture in
the air (or conduit) or until max current conditions. As long as you have
time delay fuses property sized, it would be rare for them to blow more
than once or twice over a period of many years. You could try checking the
insulation with a megger, but pulling it out and replacing it might be a
more sure fire bet. If it still faults after that, at least you know the
wire is good.

Re: [RE-wrenches] SolarEdge inverter blowing fuses

[Dave Tedeyan]

The fuses are Ferraz Shawmut Trionic TR60R. 60A, 250V. I looked them up to
find that they are time delay, RK5 type.

I would imagine that there is monitoring, but not being my installation, I
don't have access to it. That's a good idea though to get access to see
when this is happening.

I am also waiting to hear back as to whether it is both legs, or only one.
I've been to the site only once so far, to initially diagnose the bad fuse.
At the time, I was hoping that it was just a bad fuse since everything else
looked okay.

Lloyd, thanks for the insulation tip. Next time I head out there, I should
pull out the wires and take a closer look. Unfortunately it's a line side
tap, so I'm not excited about removing the tap, but may be worth it if I
can't find anything else. Although come to think of it, I did find a ground
fault in the wires for another system at the same site, so the original
installers' wire pulling technique is certainly suspect.

Cheers,
Dave

Re: [RE-wrenches] SolarEdge inverter blowing fuses

[Jerry Shafer]

Does this system have monitoring, what time of day is this happening, the
monitoring site should show output at time of failure, what leg is tripping
both or one side? You may want to look at the fuses they are using, rapid
blow, slow blow, rated for the duty these are being used for. You can also
use a data logger to get a better idea of what and when

Re: [RE-wrenches] SolarEdge inverter blowing fuses

[jay]

HI Dave,

Which exact fuses do they have installed?

I’m guessing they are blowing due to not being constant load rated fuses and 
summer higher temps.

Re: [RE-wrenches] SolarEdge inverter blowing fuses

[Lloyd Hoffstatter]

Dave,

My first thought would be a small nick in wire insulation going to ground, 
causing the fuse to fail over time.
We had a similar situation with a much larger system where the culprit was hard 
to notice…

Subject: [RE-wrenches] SolarEdge inverter blowing fuses

Hi All,

I am servicing a system that keeps blowing fuses on the AC side, although it
 appears that everything is sized correctly. It is a SolarEdge SE11400A-US 
inverter.
 Max continuous output current is 47.5A x 1.25 = 59.4A. There is a GE TG3222R
 60A AC disconnect, and it is wired up with #6 THHN wire. The terminals were 
tight
 and there was no evidence of arcing or burning in the past. This is indoors, 
and not
 exposed to sunlight. No extra conductors are in the conduit.

But they say that they need to replace a fuse roughly once per month. Has anyone
 seen this before? Could there be some kind of fault in the inverter itself that
 occasionally induces extra current? Is there any way to tweak the settings so 
that it
 actually produces a bit more than 11.4kw? I appreciate your thoughts.

Cheers,
Dave

If anyone has a copy of this form, can you please send it to me off list?

I don't understand why SolarEdge hides access to this document and makes it
so hard to take over another installer's site. I'm cleaning up a lot of
messes recently and it's really hard to support these service clients.

That seems like a pretty weak offering if that's true. It seems to contradict

Only if you turn off the disconnect on the inverter or the inverter itself,
otherwise all will remain active.

[RE-wrenches] SolarEdge - are you listening on here???

[scot.arey]

How did a company that I would tell customers had the very best tech support
in the business fall so far, so quickly.

 

This is the 5th exchange with tech support regarding StorEdge not charging.
Used to work just great.until it did not.

 

At least I'm only 34 in line.

 

SolarEdge - your Director of Sales swears thre is no problem but there
really is one.

Hi FolksDoes anyone know how to reach SolarEdge support.  We have
numerous sites with issues and have been on phone hold for well over 3
hours.  Multiple days in a row. No one answers.  We tired their online chat
tool and we are #49 on the wait list to be addressed.   This is pretty
ridiculous.  I am wondering if they are going out of business?  No way to
get support?  Any inside contacts would be appreciated.

Historically we have enjoyed using their products and even customer
support.  They used to offer a call back feature that kept your place in
line...But they stopped offering that feature.   I know this is echoing
others experiences recently.   Also the present policy of waiting 10
days to send replacements doesn't sit well with our customers.

What other inverter/optimizer combos are folks using that are proving
reliable and consistent with good installer support.  I have noted many
complaints regarding Tigo and SMA paired together. recently on the wrenches
listWhat are folks using with Fronius.  Lately their tech support was a
pleasure to work with and we didn't even have to ask for reimbursement when
replacing an inverterTheir policy is to send payment when they receive
defective inverter back.   I was impressed. Quick easy knowledgeable techs
as well.

Other suggestions are appreciated.

Thanks.

Re: [RE-wrenches] SolarEdge

[Jason Szumlanski]

One word: Enphase.

They have had issues with customer support in the past, but nothing close
to this, and recently it has made a remarkable turnaround. The support
staff is exceptionally well trained. The strange thing is sometimes I can
wait 20+ minutes and sometimes someone picks up immediately. There seems to
be no rhyme or reason regarding time of day/week. I just called about 30
minutes ago for a client and got through in about 30 seconds, and received
instant qualified, experienced, and intelligent support. They understand
what we are up against out there.

Long ship times for replacement units have been an issue at times, but that
seems to be largely resolved as well.

I have the luxury of having gained some inside contacts that get things
done for me, but even without I can say support is great. And those
insiders never complain about my direct contacts even when I borderline
abuse the privilege.

Go ahead and call me an Enphase fanboy if you will, but it has served my
business interests well.

I've been working on Enphase systems since 2009, and I can say without
reservation that this company knows how to train customer support staff. I
have had negative experiences with every major string inverter
manufacturer's customer support in the past (although a few still have my
respect). With over a decade using Enphase I can't recall a single negative
customer service experience that made me want to look elsewhere (although
phone wait times and shipping delays for RMA units were minor irritations
at times). They listened to their customers and resolved the issues. I have
called Enphase literally hundreds of times and never encountered an
employee that was rude, indifferent, or even one that lacked the requisite
knowledge to communicate with me intelligently about my issue. It's
actually quite remarkable.

Tangent: Other than cost perhaps, I just don't understand the MLPE debate.
If you are going to go the MLPE route, why not go all the way? I'm not
opposed to SolarEdge at all, but I'm very happy my installed base is tiny
given the recent customer service and hardware issues I have heard about.

Note: I own no ENPH stock. What am I thinking?!?!

[RE-wrenches] SolarEdge

[Kirpal]

Hi FolksDoes anyone know how to reach SolarEdge support.  We have
numerous sites with issues and have been on phone hold for well over 3
hours.  Multiple days in a row. No one answers.  We tired their online chat
tool and we are #49 on the wait list to be addressed.   This is pretty
ridiculous.  I am wondering if they are going out of business?  No way to
get support?  Any inside contacts would be appreciated.
Historically we have enjoyed using their products and even customer
support.  They used to offer a call back feature that kept your place in
line...But they stopped offering that feature.   I know this is echoing
others experiences recently.   Also the present policy of waiting 10
days to send replacements doesn't sit well with our customers.
What other inverter/optimizer combos are folks using that are proving
reliable and consistent with good installer support.  I have noted many
complaints regarding Tigo and SMA paired together. recently on the wrenches
listWhat are folks using with Fronius.  Lately their tech support was a
pleasure to work with and we didn't even have to ask for reimbursement when
replacing an inverterTheir policy is to send payment when they receive
defective inverter back.   I was impressed. Quick easy knowledgeable techs
as well.
Other suggestions are appreciated.

Has your client verified that it’s the inverter, i.e. have they turned off the

Re: [RE-wrenches] SolarEdge woes

[penobscotsolar]

One of my pet peeves with SolarEdge (I have a few) is that we are now
forced to buy the StorEdge inverters with GSM service, an extra $400 or so
added to the price of the inverter. The carrier is T-Mobile, which does
not work in 95% of Maine. It does not seem to work with other carriers
where we install, as well. There should at least be a CDMA option, but
there is not.
And we are seeing a lot of out of the box and infant mortality with
inverters these days. My estimate would be one in ten.

Re: [RE-wrenches] SolarEdge woes

[Howard Arey]

Hahaha!

 

You may have missed my earlier post on the topic. SolarEdge has gone from
very best, most informed tech support IMO in the industry to the very bottom
in a span of two months. Word from SE insider is that rapid growth brought
on many new folks and tech inquiries exacerbated by new SetApp inverters.

I'd say also exacerbated by a big decline in quality. We have had so many SE
failures recently my team and I just discussed moving to Enphase. Really.

I told the SE exec that there ought ot be tiered support so long-time,
proven NABCEP installers can get real support without going through pain on
tier-1 techs asking the most basic questions. But this SE exec
response.shockingly.was that the certified guys were often the worst to deal
with.

 

I'm about fed up with it. Costing me money and goodwill with customers. SE
might be looking after $$$ for nivestors but all they have done is pass
customer support onto our backs.

Re: [RE-wrenches] SolarEdge woes

[Matt Partymiller]

I believe calling at 2 AM your time would help.  Once you hit about 8:30
AM EST, you might as well just do the online thing.  Often online just
takes 10-30 minutes and you get a valid answer (though I was told by a
tech today he spent three hours going this route - hopefully that was a
one-time occurrence). I am not thrilled with the online approach but it
may alleviate some of your headaches.  You can find their help chat
button in the lower corner when on their support webpage. 

I am surprised how poor the service departments are for the majority of
inverter manufacturers.  I think I would pay an extra $10/inverter for
better support when needed.  Or a monthly club membership fee.

Re: [RE-wrenches] SolarEdge reliability declining...???

[Martin Herzfeld]

Good to know.

1.  I just installed the latest SetApp inverters (the ones without
displays) for a ground-mounted array with the inverter in the dwelling.

2.  The ground-mounted system had to comply with CEC 2016/NEC 2014 690.12
in California because the system was "in the building." Would the inverter
in an indoor or outdoor location be a factor in the failures?

Re: [RE-wrenches] SolarEdge AC coupled off-grid (part 2)

[Ray]

I've AC coupled off grid with the Sunny Island, but I haven't tried it 
with Solar Edge.  Can you adjust the Solar Edge coupling window to 
outside the IEEE set points?  We used to have set all GT inverters in 
Hawaii wider, because the utility wanted them to stay on longer in a 
brown out.

Hi Ray,
I get the issues with AC coupling.  However, this system already has a 
3+ kW DC coupled array, the new array is close to 200' away, and it 
would take 2 more charge controllers of any of high voltage ones for 
this size array.
Are there any battery based inverters that folks have had decent luck 
with AC coupling in an off-grid environment?  (My preference would be 
the XW+).

Thanks,

I do not recommend AC coupling for off grid, except to offset
daytime loads or to add PV at remote buildings. Besides coupling
errors like you're experiencing, the entire system will shut down
and not recharge, if the VFX inverters shut down.   With a DC
coupled array, the batteries can recharge, even if the inverters
have shut down for low voltage, over load, etc.  At least when
someone comes to reset it, the battery won't be dead too. The 3rd
reason, as you've found, SE and other GT manus, don't want to deal
with off grid.

There are higher voltage, higher capacity Charge controllers
available now, like the FM100, and Magnum PT 100 that could almost
handle that array with one controller.  The PT 100 will work with
Midnite's SOB rapid disconnect system.

Re: [RE-wrenches] SolarEdge AC coupled off-grid (part 2)

[Howie Michaelson]

Hi Ray,
I get the issues with AC coupling.  However, this system already has a 3+
kW DC coupled array, the new array is close to 200' away, and it would take
2 more charge controllers of any of high voltage ones for this size array.
Are there any battery based inverters that folks have had decent luck with
AC coupling in an off-grid environment?  (My preference would be the XW+).
Thanks,
Howie

Re: [RE-wrenches] SolarEdge AC coupled off-grid (part 2)

[Ray]

I do not recommend AC coupling for off grid, except to offset daytime 
loads or to add PV at remote buildings.  Besides coupling errors like 
you're experiencing, the entire system will shut down and not recharge, 
if the VFX inverters shut down.   With a DC coupled array, the batteries 
can recharge, even if the inverters have shut down for low voltage, over 
load, etc.  At least when someone comes to reset it, the battery won't 
be dead too.  The 3rd reason, as you've found, SE and other GT manus, 
don't want to deal with off grid.


There are higher voltage, higher capacity Charge controllers available 
now, like the FM100, and Magnum PT 100 that could almost handle that 
array with one controller.  The PT 100 will work with Midnite's SOB 
rapid disconnect system.

[RE-wrenches] SolarEdge AC coupled off-grid

[Howie Michaelson]

I have used SolarEdge to AC couple a smaller Array in the past, with no
issues. I recently added a fairly significant array (6.2k DC via a SE6K
(setap) inverter in an off-grid home which has had a dual stack VFX3648 for
many years.  I also added 32kWh of Blue Ion batteries replacing an 80kWh
older flood Rolls "KS" battery bank.

Unfortunately, it appears the SolarEdge is having trouble staying connected
to the VFXs.  According to the errors the SE throws errors indicating an
grid instability and excessive harmonics.  I made the mistake of telling SE
that this was an off-grid application, and they basically stopped talking
to me after explaining what the error codes mean.

I'm wondering if the VFXs are just not capable of putting out clean anough

We have had countless failures on the HD Waves, I am surprised they are

year. I have never seen an issue with their older equipment.

either. I have also noticed their tech support has also gotten worse with

Re: [RE-wrenches] SolarEdge change over with SunPower Modules??

[August Goers]

Tom - I was just asking a SunPower rep about this. My understanding is that
a PID (Potential Induced Degredation) discharge device is required to use
SunPower positively grounded modules with a transformerless inverter. These
are expensive and not listed for the US market. Long story short, I don't
think you can do it. You need to find a transformer based inverter for your
project if you're going to stick with those modules. There is a company or
two selling refurbished Sunny Boys on the market.

Re: [RE-wrenches] SolarEdge 7600 and the Powerwall

[Carl Adams]

Chris,

Nice finish on the Sonnen install.  It looks fabulous.  My understanding is
the Eco 2-8 integrate the 4kW radian, and the 10-16 incorporates the 8kW
radian.  I assume generator support is fully supported

I promised a picture of the Sonnen installation. As these units are getting
close to being appliances in the same vein as home audio, we wanted to have
a clean finish so we made some mill work to complete the top of the unit to
the ceiling and hide the ugly conduits.

Re: [RE-wrenches] SolarEdge 7600 and the Powerwall

[Chris Mason]

Howie,

The Sonnen Eco16 we installed is very nice equipment. I have previously
used the Radian 8048A inverter but the Sonnen adds a really nice battery
system, nice interface, and a Z-wave energy management system.
The battery system is by Sony and the stats are incredible. !0 year
warranty, 10,000 cycles, discharge to zero without damage, very good
battery management system.
The install was easy enough, connecting the mains cabling is a challenge as
there is very little room, I would definitely have a trough or some kind of
cable management device above the unit. It takes two people, one to guide
the cables into place and one to push them.
The batteries are so light it is surprising, one person can easily carry
them. This alone is enough reason to go Lithium.
I set the minimum battery reserve to 10%, this client wants to use as much
solar as possible.

Setting up the system is simple, there's a few parameters but they are
easily understood and the manual is very complete.
The client already had an 8KW PV system using a Sunny Boy 8000TL. That was
already connected to the load panel so we didn't have to do any solar
installation.
The Sonnen Eco uses frequency shift to turn off the inverter. This does not
work when it is grid tied, so it can't stop the inverter backfeeding the
grid, which is a problem for us. There's going to be a fix for that shortly
that will allow us to use a contactor to disable the inverter.

If you have clients looking for Lithium batteries, this is a very clean,
very easy to install and configure system.
I will post pictures after I finish the clean up, we are making a wooden
shroud to hide the conduits.

[RE-wrenches] SolarEdge 7600 and the Powerwall

[Marco Mangelsdorf]

Yes, this install was on Oahu in HECO territory.

 

HECO, HELCO and MECO have an interconnect agreement known as Customer 
Self-Supply (CSS) where the customer-generator is not supposed to export more 
than an “inadvertent” amount of surplus power to the grid.  For these CSS 
systems, battery storage is needed.

 

Note that there’s been a whopping one CSS system installed to-date by Sunrun.

Marco,

 

Thank you, your timing is perfect.  I am working with a utility to get approval 
of a StorEdge  / Solar Edge combination with Tesla batteries and potentially 
export limitation.

The utility has been asking for examples, and this is the first I can bring

Any other examples of StorEdge with batteries or SolarEdge or StorEdge using

Hi Marco,
I assume that is the StorEdge 7600? Is this your install? What was your access 
to the StorEdge?

I would love to hear more about that install. Design, sense of equipment
quality and development (is programming and function well thought out and
implemented), availability, pictures, etc. are all significant questions.
Thanks for the offer!

Re: [RE-wrenches] SolarEdge 7600 and the Powerwall

[Lloyd Hoffstatter]

Marco,

Thank you, your timing is perfect.  I am working with a utility to get approval 
of a StorEdge  / Solar Edge combination with Tesla batteries and potentially 
export limitation.
The utility has been asking for examples, and this is the first I can bring 
them back.  HECO territory?  Sorry the system isn’t yours, but thanks for 
helping  pave the way for others!

Any other examples of StorEdge with batteries or SolarEdge or StorEdge using 
export limitation would be most helpful, meeting with them on Friday,

Best regards,
Lloyd

Re: [RE-wrenches] SolarEdge comm card failures

[Carl Adams]

Howie,

Thanks for your response.  I would agree that we have not seen this problem
with systems installed after 2012.   The technology has improved, and the
Comm card in the inverter has been thru several iterations since then.  I
would also agree that SE has improved on their tech support response time
this year and the "with the paint by numbers" description of tech support
response.  Based on my limited experience, I surmised a failing
communications card in the inverter.  I had a hell of a time convincing SE
tech support this was the issue.

We were on site troubleshooting this today and after checking that we could
ping Google from the inverter connection, and establish a TCP connection to
the SolarEdge server via the laptop on that connection, and trying to step
thru the inverter programming with a non responsive push button interface,
the SE tech agreed to send us a new comm card.  But only after rolling a
truck, jumping through a few hoops on the phone with SE support, did we get
that agreement.  I felt like most of this troubleshooting was above what I
could expect of most field  techs, without significant computer experience.

Note this is the card which contains the digital display for the inverter,
and the one which interfaces with the push button display on the inverter.
This is not an add-on accessory. One other symptom of this problem is that
the push button interface for scrolling through the SE inverter menus is
intermittent in its response.  You may push the button multiple times
before you get a response on the screen.  Same behavior if you use the push
buttons under the front cover of the inverter.  Another symptom is that the
 indicator does not display on the first  and sixth display screens.
  indicates the unit is unable to connect to the Solar Edge portal.

I have two other sites which exhibit similar symptoms; missing data reports
to the portal on random days in the past few months.  The inverters are
working fine but the data is not being uploaded to the portal on some
days.  I asked SE for a part number for the comm card so I could stock a
spare.  Unfortunately they were unable to provide a part number, which I
could order from my distributor and take to the site to troubleshoot these
sites.  Apparently these are only supplied after you jump through enough
hoops with tech support.  I found this aggravating to say the least.

I hope this is helpful.

With Kind Regards
Carl Adams

Re: [RE-wrenches] SolarEdge comm card failures

[Howie Michaelson]

Carl,

We experienced a rash of Comm Card issues with several SE installs over
several years, but none exactly as you describe.  Our issues were almost
all resolved with a board replacement, but a few were particularly vexing
with many return service calls to get a resolution.  We seemed to have the
most problems with the single phase 10k inverters.  In general, SE tech
support was helpful, although a bit paint-by-numbers at times, as well as
very slow to answer for much of 2015.  As best I can tell, the issues have
begun to settle down most recently.

Anyone experiencing issues with comm card failures on SolarEdge inverters?
We have some systems installed  in 2012 exhibiting similar behaviors.  The
systems are producing data, it is registering on the inverter, and our
independent utilty meter, but is not reported to the SolarEdge portal.
Next day(s) it reports production to the portal but the missing data is
never filled in.  I have attached a small graph from the portal dashboard.

Typically if a network connection goes down, and then is restored the data
should be uploaded after the connection is back on line.  In this case
their remains a hole in the data, for that day, indicating that data was
never uploaded.

We had one system which exhibited this "missing data" symptom on accasion
over a 2 month period of time.  This was diagnosed, as a failing comm
card.  Once that was replaced we have not seen the issue recur for that
site.  But now we are seeing similar behavior from three other sites, all
installed a in the second half of 2012.

Just wondering if anyone else has encountered this.

Thanks

Kirk:

 

And a PR nightmare for integrators.  The customer will be very disappointed 
that you have to charge at least several times the cost of the battery pack to 
make it provide back-up power.  The overly rosy picture painted is a disservice 
to the industry.  

 

On a related note: It is 2015-- where is my flying car?

 

William

 

PS:  I can see retrofit battery banks as practical when used for peak shaving, 
as long as you can live with the losses.  Providing back-up power, other than 
cord connected, however, is a much more difficult endeavor.

Re: [RE-wrenches] Solaredge Storedge

[Kirk Herander]

The hype is deafening on this. I agree in the Storedge design there appears to 
be no way to separate out critical loads for operation during an outage, unless 
the homeowner manually turns off non-critical circuits. Not ideal.

As for the Powerwall itself(not part of the Storedge system), they say 10kwh od 
storage costs $3,500. Hypothetically, that might be good for 24hrs of critical 
load power, maybe. But not usually in Vermont(Green Mountain Power territory), 
where multi-day outages are not uncommon. So in my area you might need two of 
the Powerwalls and still need a battery-based inverter.

I haven’t read the article yet, but do have a copy. My question is what makes 
the Powerwall anything more than a wall-hung battery enclosure with lithium-ion 
batteries? Look at all the extras you need to make it work without(we hope) 
limitations. I am disappointed that GMP, my State’s largest utility, can paint 
such a rosy picture of an unproven product. The romance will quickly fade  when 
sticker-shock of the real expense of battery –back up is exposed. It could turn 
into a PR nightmare for GMP.

I hear you loud and clear Kirk. On the one hand it is pretty cool to see so 
much interest in battery-based systems, on the other hand the level of 
misinformation being spread around is frightening and time-consuming to combat.

 

There is a Bill McKibbon article in the New Yorker this week where he 
unfortunately, loudly and clearly, repeats the Tesla marketing spiel. He 
reports from the CEO of Green Mountain Power  -  "Powell was excited by its low 
price: three thousand dollars, far below what analysts had predicted, and low 
enough that her company could immediately begin installing it for customers, 
especially those who wanted backup electricity in case a snow-storm disabled 
the grid." 

 

Here's  a link the article:

The more I re-read this the angrier I get, and honestly it would be awesome to 
send a group co-signed letter to the New Yorker refuting this inanity and 
telling Bill M to do his homework. Send me an email off-list if anyone wants to 
follow-up.

Available tech info on both Powerwall and Storedge is basically zero. Too bad

Re: [RE-wrenches] Solaredge Storedge

[Chris Mason]

Just to add a little perspective on the development of inverter based
storage, I have just attended InterSolar Europe in Munich. Every inverter
manufacturer is showing some type of add-on battery storage system.
SolarEdge was huge, they had the largest visibility of the inverter
manufacturers.
The reason for the rush to develop storage is the change in the European
market. Grid tied solar on a large scale is largely dead in Europe. There
were a number of panel discussions about where the focus should be, and all
the module and inverter manufacturers were pretty glum.
The only perceived area of growth is self consumption, and to maximize
that, inverter manufacturers need to have storage. So the aim is not to
provide grid independent systems, the design goal is to use all the power
production in house and to avoid exports to the grid, while being
grid-tied.
So the development of these products is not US focussed, which explains why
the US distribution people don't know what's going on.

[RE-wrenches] Solaredge Storedge

[Kirk Herander]

Hello,

Anyone have detailed info on the Storedge battery-compatible system from
Solaredge? I only found a brochure on their website. Apparently batteries
can be added to a new or existing Solaredge inverter (the brochure says they
have partnered with Tesla's Powerwall) for backup power. They call it
"DC-coupling".

Re: [RE-wrenches] SolarEdge with AC coupling / Sunny Island

[August Goers]

Hi Tom,

I might be missing your question, but I believe that you would couple the
SolarEdge inverter to the AC1 line of the Sunny Island, just like with any
grid tie inverter. In other words, the SolarEdge inverter would tie into
the critical loads panel that is fed by the Sunny Island.

Best, August

Re: [RE-wrenches] Solaredge inverters w/ backup generator

[Exeltech]

Chris,

Even if a manufacturer agrees with you on incorporating an external shutdown 
option, don't expect near-term action, especially on existing models.  A 
modification of this nature obviously affects the hardware aspects of an 
inverter.  This alone mandates retesting of at least that aspect of the 
inverter by the NRTL that issued the original UL1741 certification.  If the 
change also involves software, retesting could be even more extensive.  Every 
model incorporating this feature would be affected.  It can take months of 
waiting in line before equipment can be submitted to a NRTL (depending on the 
backlog at the lab); and even more months after that for the lab to complete 
their product review and re-test.  If anything fails during the review/re-test 
process, the clock winds backwards - sometimes to the beginning (depending on 
the steps required to correct the flaw).

While an external "inverter disable" function may appear to be a very basic and 
straightforward addition, it's not.  In most cases, your request will be more 
easily incorporated into new designs that haven't yet been certified, than get 
it added to present production.

Personally, I think an "interlock" on a string system is a reasonable request, 
and likely to appear in future models from different manufacturers.  It's just 
going to take time.

The "Door Open" switch is a very useful feature. I am trying to get Fronius to

Re: [RE-wrenches] Solaredge inverters w/ backup generator

[Chris Mason]

That's total nonsense. Most of our installs involve a generator, as
generators are very common here due to intermittent electrical supply and
hurricanes. We also sell and install generators and I am a tech.
A decent heavy generator will produce electricity that will fall within the
IEEE 1547 specifications for grid tied interconnections. Additionally, in
our area, we alter those settings to widen the windows as the electricity
supply on an island is not as stable as a large grid.

My rule of thumb is that no lockout is required if there is no risk of
backfeeding the generator, that is, if the load will always exceed the
solar output by a reasonable factor. We have customers that have constant
loads in the 40 to 80KW range, and so 20KW of PV will never cause a
problem. Residential is the larger issue, as there is often no load.
A generator's output is controlled by the Automatic Voltage Regulator or
AVR. It senses the voltage at the terminals of the alternator and changes
the excitation to keep the voltage constant.
Usually the generator's controller has voltage sensing and will stop the
generator if the voltage exceeds limits.
If the solar inverter is making power and there is no load, it will
increase the voltage until it finds enough load, or trips. If the generator
sees the increased voltage and the AVR cannot reduce the excitation enough
to control it, the controller MAY shut down the generator.
A generator's controller and AVR presumes it is the only source of power on
the electrical system. The inverter presumes it is connected to an
infinitely large grid system that can absorb all power generated.

Our usual solution is to put a contactor in front of the inverter
controlled by voltage from the generator, or ideally by a contact on the
transfer switch.

It may be possible to program the generator to run faster or slower so as
to keep the frequency outside the inverter limits, but you run the risk
that a future tech will adjust the inverter or generator.

[RE-wrenches] Solaredge inverters w/ backup generator

[Kirk Herander]

Hello,

 

I recently posed the question to Solaredge tech support, wondering if their
inverter, in this case a 20kw 480 3-phase, would have any issues if it were
connected to an AC panel backed up by a generator. They told me no problem,
for the inverter's anti-islanding will work if it sees the "generator
frequency" and therefore will not try to push PV power to the panel. But
isn't 60 hz, 60hz regardless of origin? There's got to be more to it than
that. I question this because I asked the same to SMA several years ago and
they were hard-set against connecting Sunnyboys to a panel with generator
backup, so I always would establish the point of interconnection upstream of
the generator feed. Comments? Thanks.

[RE-wrenches] Solaredge 480v 3-phase inverters

[Kirk Herander]

Hello,

 

Has anyone on list installed a Solaredge 480/227 3-phase inverter? The spec
sheet says that the nominal input DC+ to DC- is 840vdc. I assume this is the
regulated operational voltage, and so the system installation falls under
the code rules for 1000vdc systems, correct? My local utility has balked in
the past to allow installs of inverters greater than 600 vdc input. Thanks.

SolarEdge makes an optimizer / inverter system. We just installed one. Our
clients are happy. So are we.

Don't know if you can AC couple the inverter. Their website says they are about
to release a version of the optimizer that will work with other manufacturer's
inverters.

Re: [RE-wrenches] SolarEdge Optimizer - Was: Tigo and SMA AFCI - Was: AC coupled, grid-tied Sunny Island - contactor & bypass

[Richard L Ratico]

SolarEdge makes an optimizer / inverter system. We just installed one. Our
clients are happy. So are we. 

Don't know if you can AC couple the inverter. Their website says they are about
to release a version of the optimizer that will work with other manufacturer's
inverters.

Re: [RE-wrenches] Solaredge AC-coupling revisited

[John Berdner]

Kirk:

Yes, the latest version of firmware in the SE inverters supports AC coupling to 
SMA Sunny Island, and to a degree with Magnum (off grid systems).
We do not support AC coupling with Outback because they do not yet do frequency 
shift.

If you should get an inverter with older firmware we can update firmware two 
ways:


1)  Remotely update firmware for any inverter connected to the internet.

2)  All inverters with Suffix "A-US" have an SD card slot and we can send 
you a file or an SD card to update.

Unfortunately, I have not finished the White paper but briefly...
We need to activate the advanced power control features and then there are 4 
parameters in the inverter that need to be changed.
Our support people can walk you through the programming (a bit cumbersome) or;  
we can program it remotely if connected to the internet or;  we can create an 
SD card.
We can easily program our inverter match the Sunny Island frequency shift 
algorithm.
If you change any of those parameters then you would need to make the 
corresponding change in the SE inverter.

I am not understanding your concern regarding frying the battery and regulators.

A couple of easy solutions to what I think you are asking ...
Use a relay between the grid tied inverter and the battery inverter.
Control this relay with a voltage controlled relay or, use one of the aux 
relays in the SI to control it.
You need to be careful doing this to insure that the grid tied inverter 
disconnects only during a charge control failure.
You might need to disconnect this function during equalization which can be 
tricky.
Repeated disconnection of the grid tied inverter will shorten the life of the 
grid isolation relays in the grid tied inverter.

You might also consider a diversion regulator as a backup to conventional 
charge control.
A simple on off relay to an AC hot water or space heater can dissipate a lot of 
power relatively simply and inexpensively.

I have like many of you installed both micro inverters and solar edge

For installation the optimizers were a lot faster than the micro's to install, 
nothing is a fast as a string inverter.  I am sold on the optimizers, as I see

Wrenches,

I wish this urban myth about electrolytic capacitors would
die, but it won't.  It's been a wonderful marketing ploy for
some time now.

Simply stated, existence of electrolytic capacitors in inverters
does NOT mean the inverters are less reliable.  Satellites
have been using electrolytic caps for decades, and look
how long THEY last!  (I know, because I've helped to design
power supplies for aerospace applications.)

What it boils down to is this: if a quality electrolytic capacitor
is used within its specifications, you can expect 60+ years
of life from it in an inverter application.  Conversely, if a
circuit is poorly designed, you can ruin any electronic part
in a very short time.

What defines capacitor "life"?  It's defined as the doubling
of the internal effective series resistance of the capacitor
from the value it had when it (the cap) was new.

This is energy lost.  It also causes the capacitor to operate
at a slightly higher internal temperature than when it was
new (all other factors being the same).

Result?  It all depends on how the circuit is designed.  In
our case, the inverter efficiency decreases approximately
a quarter to one half of a percent.   The waveform distortion
also increases, but it takes lab grade equipment to detect
the change.  If you're worried about a 1/2 percent drop in
the inverter efficiency, your concern is misplaced.  After all,
PV degrades over time much more than that!

So why the bad rap on capacitors?

Like tires, they DO wear out.  40 years ago, "premium"
tires were rated for 30,000 miles.  Could you wear them
out in less?  Absolutely!  Drive like a 16 year old kid with
a muscle car, and it's easy.  On the other hand, I just bought
a new set of tires.  The old ones still had tread, but at 88,000
miles, they'd seen their better days.  This is a far cry from 30k
mile tires.

Capacitors have progressed in the same manner.  A long time
ago, capacitors wore out in 5 to 10 years.  Today, it's an entirely
different story.

As long as the circuits in which the electrolytic capacitors are
used are well designed, you have nothing to worry about.
Electrolytic capacitors in a well-designed application will outlive
all of us.

All,

We had a component quality problem with some early production batches.  
Unfortunately  you guys in the field had to go thru a fair amount of grief 
before we wrapped our heads around what was going on, identified the root 
cause, and fixed the problem.  We absolutely stand behind the product, and also 
provide compensation for your time in dealing with our quality issues.

There are still occasional "glitches" in some installations, but the current 
generation of product is proving to be very reliable, and the "out of box" 
failures have dropped significantly.  Never low enough for me, though.

That's all I want to post here, but you know how to get in touch with me if 
you'd like to have further discussion.

The fact that by hitting the "off" switch on the inverter will reduce the
