Mac, my advice, just to be sure, check the refractometer against a float
hydrometer on real battery acid from your home system, not just the the
distilled water zero mark.

Mac,
In my experience, cells that read 1.0 rarely if ever recover to a usable
state. I've also seen abnormally high SG readdings (1.31+) in battery
banks that are over charged, which may be the case here. You stated the
set points for absorb and equalize, but was this just for the VFX or for
the
Thanks for the responses everyone. I never considered that acid may have
been added. I'll have to press him a little bit on that. He's definitely
"old school" so I wouldn't be surprised if he tried this. Dan, I
calibrated the refractometer, so I have confidence in its readings. When I
say all
Mac:
Someone has added acid to the cells. I've had the same experience and found out
the truth later on.

I would stop there and see if it is corrected. I have seen high SG when
there is little or no boil offand water is not added, if someone has added
acid the SG is not usable. You can use the entire system as it is a load
tester turn off the pv, gen set and the wind put a 2 k load (ac) on the

Hello wrenches,
I just went on a service call for a new client. He had a bank of 4 year
old Interstate L16HCL batteries, 2 strings of 8, 48V system, 840Ahr. We
went through the batteries and got specific gravity on all of the cells
post-equalization
I generally use specific gravity as a way to measure the differences
between individual cells, batteries and strings, not relying on the exact
reading, to get an idea if there are problems (usually connections) in part
of the battery bank. You also said SG readings were all over the place.
I'd fir
Hi Jerry,
I think his issue was the generator was starting at around 4-5am on some
days. I think this may have been a programming error, I lowered the start
voltages on the AGS.

Hello wrenches,
I just went on a service call for a new client. He had a bank of 4 year
old Interstate L16HCL batteries, 2 strings of 8, 48V system, 840Ahr. We
went through the batteries and got specific gravity on all of the cells
post-equalization. I was a bit surprised to see some very high
