Re: [RE-wrenches] LG CHEM

[John Blittersdorf]

Marco,
   I have only installed one LG Chem 10H with the StorEdge inverter for
backup power in a vacation home and it has performed wellmany times over
the last two years
in power outages.  Much easier installation than than dealing with Tesla
Powerwall.

Re: [RE-wrenches] Sol-Ark Inverter?

[John Blittersdorf]

Ray,
   I just quoted an off-grid project using the Sol-Ark.  I use Alt-E for a
supplier and they suggest the Midnite solar Mini-DC disconnect for the
battery.  They
have heard good things about it and I am going against my previous
requirement using one first or at least seeing one in action before making
my customer the guinea pig.
I will know in a few weeks how it works out.

Aloha all,

I would be very interested in hearing feedback on the LG Chem RESU10H

As far as I know, it's only been compatible with either the SolarEdge
StorEdge or SMA Sunny Storage inverters.

Re: [RE-wrenches] Schneider tech support AWOL?

[William Miller]

Ditto here. I tried it when the subject first came up and heard nothing. 

Therefore it was very handy to know the one digit, unannounced extension for 
tech support during a recent problem with XW inverters.   I know we weren’t 
supposed to share that one digit number, but I am very glad we did. 


And by the way, I reached competent tech support immediately on the first try 
and after about 10 minutes on the second call.

Re: [RE-wrenches] High altitude off-grid systems

[Lones Tuss]

Hello All
Outback’s Product Warranty is not based or negated by the altitude of the 
installation.  Altitude ratings ensure full spec operation of the equipment up 
to the stated elevation . As noted in several posts due to thinner air cooling 
of equipment can be affected. Additional cooling may be required and or 
additional products to achieve the necessary load requirements.

Here is the math, well the answer at sea level your body has 14.70 PSI exerted 
on it, at 10,000 feet you only have 10.163 PSI, reduced air pressure, reduced 
cooling or heating ability adjusted for standard sea level temp or just over 
69%.
I have done work in Hawaii on the big island up at the summit, it can be warm 
and very thin air, without air to cool no inverter will perform very well. I 
have some SMA, FX and Raidians in warm high altitude locations and added extra 
cooling to compensate for the lack of air. You will hear the cooling fans 
spinning faster, moving less air at higher altitudes.
SMA sunny island does have a 9k plus operating altitude but de-rates at less

We do a fair amount of systems at "altitude".  Recently we had an issue with a 
Radian system at about 10,000'.  An 8048 inverter screaming (fans running hard) 
with just 2000 watts of load.  I hounded tech support for two years, and even 
after switching power modules, etc in the end the techs claim a fairly 
substantial deration (that I can't quote right now) of inverter performance 
because of cooling issues.  We  ultimately added another inverter to the system 
at the end of last summer.  I hope this season we will see a better result.   
It makes sense, given the difference in air density, but I do scratch my head 
and wonder why we haven't seen such issues with the older FX's, and some of the 
older legacy systems?

I also know that the Midnite classic charge controllers seem to run the fans 
quite hard as well.  I haven't had to replace any of the fans, and the 
controllers are performing great, but wonder if that will be an issue in the 
future.   It would be great if some manufactures would give us a quality, 
competitively priced, equipment that is rated for altitude, but I don't think 
there are that many options out there as of now

If I remember correctly the main issue with the high altitude installs are some

the electrolytic capacitors.Of course, the specs vary from component to

30,000 ft.   It really just depends on the part(s) that the manufacturer used 
to build the product.

As you gain altitude the temperatures and the air pressure decrease, as it was 
explained to me years ago the problem is with the temperature decrease, this 
will affect the capacitance of the capacitor.  The colder temps will reduce the 
overall capacitance of the capacitor, just like it will with a battery.

These caps are generally used to filter noise from circuits, so when these 
fail, or the capacitance values fall, you don't get the filtering you need and 
this induces noise into your circuitry possibly causing overall failure or 
worse,  the dreaded intermittent failure.   Generally, if the 
inverters/controllers are kept on and warm, you won't have too many problems, 
it's when they are in extremely cold temperatures is when you will start having 
issues.

Hope this helps!   Have a good weekend!

[RE-wrenches] Sol-Ark Inverter?

I just had a customer get a quote for a Sol-Ark inverter from an online 
sales outfit.  Does anyone have any experience with them, ever seen one, 
installed them, etc?  From the limited info I can see, they do not 
appear to have a UL listed battery disconnect system; I'm seeing flying 
battery cables in the few actual install pics.  They also claim to be 
"EMP hardened".

Re: [RE-wrenches] High altitude off-grid systems

[Steve Higgins]

Not to add fuel to the fire... and it's been almost 7 years since I've been
with an Inverter manufacturer so here is my .02 cents...  So again, I hope
I'm not overstepping the boundaries of the Wrenches list.

If I remember correctly the main issue with the high altitude installs are
some of the components that are used to build the inverter/controllers
aren't rated to be used at high altitude, one of the main components that
have this issue is the electrolytic capacitors.Of course, the specs
vary from component to component.   I've seen some rated as low as 8000 ft
to some as rated as high as 30,000 ft.   It really just depends on the
part(s) that the manufacturer used to build the product.

As you gain altitude the temperatures and the air pressure decrease, as it
was explained to me years ago the problem is with the temperature decrease,
this will affect the capacitance of the capacitor.  The colder temps will
reduce the overall capacitance of the capacitor, just like it will with a
battery.

These caps are generally used to filter noise from circuits, so when these
fail, or the capacitance values fall, you don't get the filtering you need
and this induces noise into your circuitry possibly causing overall failure
or worse,  the dreaded intermittent failure.   Generally, if the
inverters/controllers are kept on and warm, you won't have too many
problems, it's when they are in extremely cold temperatures is when you
will start having issues.

Hope this helps!   Have a good weekend!

Re: [RE-wrenches] High altitude off-grid systems

[chris]

Folks:
 
The issue here ulltimately isn’t whether it works or not, it’s if it’s 
WARRANTED.  Some purchasers (in this case the USFS) mandate that all equipment 
be warranted for high altitudes.  And that leaves out several major suppliers.

We've had some systems at 11,000 ft plus, for almost 20 years.  We have 
mixtures of Outback, Midnite, Blue Sky, and old Trace equipment.  Never any 
issues with electronics related to altitude.  Actually the altitude related 
system issues are generator derating, and array output exceeding STC ratings on 
really clear cold days due to the thin atmosphere.  The third issue would be 
installers not being able to catch our breath after jogging back to the truck.

The alitude de-rate stuff seems to involve dialectric ratings on the 
transformer coils, and low air density for cooling. I think that's all in ANSI.

Hi folks:
 
I am curious as to how many of you sell/install battery/inverter systems at 
high altitudes?  Have you had any particular issues with them?  Last year we 
discovered (in a mostly costly fashion) that Schneider inverters (and also 
Outback) are not warranted above 6500 ft.  
 
Magnum inverters are warranted to 15,000 ft max altitude.
