Jason,
We have had no demand for systems with no PV here in Hawaii but we are just
a small outfit.
As far as generators and Sol-Arks. We have always managed to get generators
charging with Sol-Arks but it seems to be a challenge. I'll state the 2
obvious things which have tripped us up in the past
We are seeing an uptick in consumers looking for whole home battery backup
systems without solar panels for shorter grid outages. They either want
battery only or battery with generator charging capability, either portable
or fixed.
I was planning on offering primarily Sol-Ark 15k for this scenari
Jay,
I thought it was broken when I first saw it also but its not. I agree
that it is snail trails which are cause from chemical reaction of the
different components with moisture. Generally low grade module.
I don't know how many modules have snail trails. The array is 10 rows by
20 columns
Any decent meter will have a high input impedance on the Volts setting otherwise it would provide an inaccurate reading. Our customer, who first reported this, is an engineer with a well-known charge controller/inverter company. He used a cheap meter whereas I used a Fluke 87-5. Both had the same r
My first thought is what meter are you using? Some meter will have high
input impedance and give false value

Yes, that’s my expectation. The output is at such a high impedance that as soon
as you put any load on it, it would drop to 0.

It would be interesting to see if there is power there. Like put a low wattage 120v incandescent light bulb on it. If it was static wouldn’t the meter drain the volts? JayOn Oct 28, 2024, at 7:31 AM, rick--- via RE-wrenches wrote:An update on this “issue”. Sol-Ark Tech Support said that the high
An update on this “issue”. Sol-Ark Tech Support said that the high voltage DC
is normal and not a concern. I believe they said it was a “static” voltage.
They didn’t really provide an answer as to why it’s present. But I stick to my
hypothesis that the source is the H-Bridge drive circuitry.
