Larry, et al.
Yes, good point< I should have mentioned the batteries are only
1 1/2 years old. There are many of the first time homeowner mistakes
going on here...not a good site for winter sun due to tree shade,
batteries in cold environment, didn't mention a recently sporadically
working CC, etc. Its the whole enchilada.
Though I just met the customer he's a nice guy, burned by the
first dealer and very un-solar-educated. I want to help him but he has
very few funds. After a thorough thaw, we thought we would "test" 2
batts on a car trickle charger (his friends' house) to see if/how they
respond. I've been training him on monitoring temps, electrolyte,
keeping the amps low for the first many hours and watching, documenting
voltage. If he wants to spend his time doing this to see if some life
can be scratched out of all that sulphation, I'm willing to mentor
him...for now.
I know we been in this discussion before but the frozen cells
were a new twist for me. Thanks you guys,
Bill

Hi Bill,
You did not mention the age but I would bet that the batteries have
more of a problem from being deficit charged since the owner has no
alternative charge source. So many DIY systems are poorly designed and
usually underpowered. We see T-105’s murdered in just 2-3 years. Top
that off with the likely damage from the big freeze event and I would
condemn the bank.

Hey Folks,
I came across an off-gridder yesterday whom was getting zero
support from the dealer he had purchased his small system from, self
installed, batteries in a lightly insulated box outside. When I
inspected the electrolyte levels I discovered it was frozen in some
cells, the voltage of the 48 volt pack was ~8 volts, I didn't check
individual batteries due to these facts...I'd seen "enough". Recently
temps have been in the high teens, though we are back up to low 30's.
He does not have a genny or battery charger! I have a DC genny
which I could use to charge these batteries but should I waste my time
and his money trying to save them? Others' experience with this
situation?
TIA,
Bill
