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. <br>
<br>
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.<br>
<br>
I know we been in this discussion before but the frozen
cells were a new twist for me. Thanks you guys,<br>

Hi Bill,
<div class=""><br class="">
</div>
<div class="">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.

<div bgcolor="#FFFFFF" text="#000000" class=""> Hey Folks,<br

<br class="">
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.<br class="">
<br class="">
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?<br
class="">
<br class="">
TIA,<br class="">
<br class="">
