[RE-wrenches] Floating PV arrays

[Chris Daum via RE-wrenches]

Anybody know where a residential-sized floating array (for twelve Canadian 
Solar 410W modules) might be had?  All the companies I’m contacting say I’m too 
small a fishie to lay out a line…  Please feel free to contact me off-list.
 
Thanks.

[RE-wrenches] Cry for help about 50 miles N of LA

[Chris Daum via RE-wrenches]

Dear people:
 
I got a call from a fellow that needs someone with experience with Trace
products.  He's got an SW4048, installed in 2000 (and he's close to Thousand
Oaks, in Ventura County), that has been working until lately.  But he's
looking for a good troubleshooter and all he can find is folks who want to
sell him a new inverter.  Apparently no one in his area does anything but
grid-tie; this fellow is on grid but has been using this system as a back-up
for critical loads.  He may just need some replacement circuit boards, and
he is very happy to pay for someone to figure out exactly what his problems
are - but he's not ready to throw in the towel on his inverter.
 
Any takers?  Please feel free to contact me off list.
 
Best,

[RE-wrenches] Off-grid array far, far from the batteries

[Chris Daum via RE-wrenches]

 
The crazy things folks do.  Dear people:  We have a fellow who has an
initial off-grid array with a Radian 8048A (and related e-panel, etc.) and
six 410W Canadian solar modules.  He has six more of the same modules.but
the ideal site for solar is 900 feet away from his batteries and the rest of
the system.  Yeah, good planning, right?  
 
In terms of getting AC power out of his 'new' 6X array, Enphase won't work
since he doesn't have an Enphase system.  We're looking at perhaps SMA or
Chilcon (so the size of the wire run won't be so astronomical).  Any
suggestions?
 
Best,

Jeremy,

I think the Solar RacksWorks TPMs are virtually identical to the DPW TPMs. My 
go to TPM is General Specialties  ; 
They are a solid design and I think they are easier to assemble. They also have 
UL listed TPMs but they have top mounting clamps, and for the life of me I 
don't understand the logic of of a top mount clamp on a TPM.

[RE-wrenches] generator charging question/VFX3524

[Chris Daum via RE-wrenches]

Hi folks:
 
So, we have a customer (equipment not acquired from us)  with an older OUTBACK 
VFX3524, charging their 3 X RB24V200 ReLion LFP batteries vis a vis one leg of 
their generator.  The battery is capable of up to 200A recharge though the 
manufacturer recommends 10~100A.  The customer has a 240VAC generator with two 
120VAC legs; customer wants to bump up the charging to over 22.5A, preferably 
more; they’re running their gennie a lot to get a rather slow rate of charge 
from the inverter’s charger. Presently the customer has the Inverter/charger 
connected through the FLEXware 250 enclosure. There is not a busbar in place.  
The idea presented is to use an external battery charger that would pull from 
the other leg of the 240VAC gen set to supplement the charging capability.   
The question becomes: can we use a busbar with disparate amps charging to bump 
up the charging rate for the LiFePo4 battery?  Outback techs are saying the 
VFX3524 is not LiFePo4 compatible, but they also say they need to stack another 
inverter. I think we are looking at letting the smoke out of the 
least-producing charger by pushing amperages back.   What do y’all think?  Any 
and all ideas are under consideration.
 
Best,

[RE-wrenches] Conergy solar module issues

About 10 years ago we sold some Conergy 250W solar modules.  Well, they

unhelpful.

[RE-wrenches] Generator question

[Chris Daum via RE-wrenches]

 Hi folks:
 
We have a situation where the Sol-Ark 12kW Inverter isn't able to adequately
manage the loads and perform auto-gen start other than low battery level.
And despite thorough understanding of the customer's initial loads, after
he's bought the system, he's continued to add more and more loads - a severe
case of load creep. 
 
He's got a 38KW generator and we're looking for the components to make the
generator load responsive instead of just kicking on when the battery
voltage is low.  Are there any ideas on switching equipment that can do this
and work with the Sol-Ark?  We're waiting for a reply from Sol-Ark, but
thought you folks may have some ideas.  
 
The original design was for a larger solar system and inverter, but the
customer balked at the cost and said he'd reduce his loads accordingly.
Unfortunately, that has not happened!   Now we're trying to bend the laws of
physics and have his 38KW  generator make up the difference. We need to come
up with a means of accommodating the compromised design and now are faced
with additional loads -- along with a significantly reduced solar array.
Is there a way to make this (2 wire start) generator more load responsive?
 
Thanks for any and all advice!

[RE-wrenches] Power conditioner for Trace inverter

[Chris Daum via RE-wrenches]

Hi folks:
 
I have a fellow with a Trace SW5548, purchased from us in 2001.  It's been
working  great for him all this time, but the dilemma is he's gotten a new
Hotpoint washing machine, and its electronics don't like the old inverter.
Is there some sort of power conditioner or 'line tamer' available that will
work for this appliance's operation?  Any ideas would be greatly
appreciated.  He's rather loathe to replace his inverter if he doesn't need
to.

SB3800U. Its one string of 23 PVs.  Full sun, 75 degrees ambient during 
testing. When I checked DC voltage at the inverter landings I got ~23-29 
volts (fluctuating) same at the input side of the DC switch.  These 
panels have the old gasketted 4-screw covered J-boxes and screw 
terminals inside, I removed the covers from three panels and got 9.5 
volts at the each of the panels' screw terminals,  all the wiring 
outside the boxes checks out.

 The system had been functioning normally 3 weeks prior. I 
could check voltage at more panels I guess.  Ideas?

[RE-wrenches] Magnum MS4024 grief

[Chris Daum via RE-wrenches]

Hi folks:

We have a new Magnum MS4024 mounted on an E-Panel using a MidNite Classic 150 
and Whiz-Bang JR with power coming from an array of Trina TSM365-De06X-05(II) 
(three strings of three) with the ME-RC50 and a HUP SolarOne 6-85-14/24 battery.
When we attempt to use the PFC (Power Factored Charger), the Gen Set’s GFCI 
outlets trip.  Thus far we have verified the connections are secure, assured 
that the gen set is grounded, disconnected the jumper within the E-Panel 
between the ground buss and neutral, checked AC voltages, removed the MNSPD’s 
from the buss(s)…  Stumped now on what an appropriate next step should be.  How 
do we get the PFC to function properly?  What are we missing?

Best,

Chris Daum

William,
 
$4200 sounds like “Expedited” Shipping and that usually means a Hot Shot driver 
with single pickup truck and trailer driving door to door for just your items.  
LTL should never be $4200 unless we are in dire conditions.
 
I hope your items arrive in excellent condition!!

I am sure all of you are aware of the skyrocketing costs for shipping.  I get 
it that fuel prices are up and I want truckers to all earn a fair wage.  
However I can help but feel there might be some gouging.  For instance, a $900 
order for rail was quoted at $4,200 for shipping from Oregon to the central 
coast of California.  
 
Fortunately the vendor allowed me to arrange my own shipping.  I used a website 
called Shiply and got a quote for just over $600 for the same order.  The 
company I engaged, Globaltranz has been great in communicating concisely and 
promptly with me and the vendor.
 
I think the beauty of using a broker is you can connect with shippers that 
might be travelling the desired route already and can fit your order into an 
LTL rig already on the road.
 
The order is not here yet but it is on the way and it appears the transit is on 
time.
 
I hope this helps some of you in procuring the parts you need in a timely and 
cost efficient manner.

[RE-wrenches] Frequency converter?

[Chris Daum via RE-wrenches]

Hey folks:
 
A would-be customer is building a home in the Caribbean, where they utilize 
230V, 50 hz.  But he cannot find the appliances he wants in that voltage & 
hertz range; is there some large frequency converter that he can hook to their 
(230V 50hz) grid that’ll convert it to 120/240V 60 hz?  He’s not too efficient, 
peak loads are apt to be around 20kwh….  Location is Dominica, with a reliable 
utility.
 
Thanks for any ideas you may have!

Re: [RE-wrenches] heating pads for batteries

[Chris Daum via RE-wrenches]

Hello all you brilliant people:
 
Does anyone have something new for lightly heating a battery bank in a cold 
climate?  Something reliable and reasonably efficient?  We’ve been selling LFP 
batteries for a while, but few to our northern customers who cannot keep them 
from freezing.  I can give advise about insulated battery boxes (and have one 
myself), but surely there must be something new out there.  
 
Here we see low temps of -20F below – sometimes -40…..
 
I recently spoke with a fellow who offers heaters for gutters to prevent ice 
creep that can ruin your shingles or roof, but there must be something more 
adaptable than that.  Any suggestions?

Anyone else having issues regarding a total lack of tech support of Magnum 
products?  We have a failed MS2812 inverter a customer bought last September of 
2021, and we’ve tried repeatedly since August 16 to get any response.  All we 
hear back is their auto-responder saying ‘they will be in touch with us 
shortly’.

[RE-wrenches] Magnum inverter/generator integration problems

[Chris Daum via RE-wrenches]

Hi folks, I’m trying to help a fellow with two Magnum Systems; one of them will 
accept his Honda EG5000CL gen set, the other will not.
After running for a bout 10~15 minutes the circuit breaker pops on the BMK.  He 
will be rebooting his BMK this evening in the first attempt at getting his 
system back up.   He has been powering this system with a Predator 3500w Gen 
set, along with his solar array.
The system will not accept the Honda.  Any ideas of clues to check out?
 
Sincerely,

Hey now all you off grid designer/installers,
 
I just had a conversation with generator manufacturer (name withheld for the 
moment), about 8-13KW water cooled gensets with UL & LP gas powered. I 
explained that there is a long time hole in the market since Onan & Kohler 
dropped their gensets for prime power in this size range.
 
If they made the investment to produce & UL certify a 13KW - 1800 RPM - water 
cooled – 2 wire start, prime power rated - 120/240vac genset, how many off grid 
systems are being installed with oversized gensets?
 
If this was available how many units would each of you be interested in per 
year? I am not asking for a commitment just a market survey for this sized unit.
 
If there was 20-30 companies selling 4-5+ each per year this might be a 
possibility.
 
Let me know either off list or on list (if this is OK ? Michael let us know) & 
I hope there is a possibility here for more appropriately sized & available 
gensets for our off grid client systems.
I will be passing along this research to the OE manufacturer. If you do not 
want your name passed along let me know for now.

[RE-wrenches] Wire short?

[Chris Daum via RE-wrenches]

Hey folks:
 
We have a problem we just can’t figure out.  We have a customer in OK with a 
simple array of eight Trina TSM 310-DD05H(II) modules, four stings of two 
modules into the combiner (Midnite MNPV6).  Simple, right?  He connects two 
modules, gets his 73.2VDC and lands his PV output leads on the circuit breaker 
and discovers he only has 39VDC.  So, what are the possibilities?  Loose 
connections at the MC4 connectors?  Bad blocking diode?  Ideas anyone?
 
He’s in Henryetta, OK, and we cannot seem to find anyone local to help him.  
All ideas appreciated!
