<p>Hi Mac;</p>
<p>That system sounds like a couple of systems I looked at last
year. SW inverters and the batteries back in a crawl space with
(surprise) no watering. We ended up decommissioning one of those,
as the new owner was no longer interested in solar backup. The
crawl space definitely doesn't meet code, and doesn't meet even my
basic 3rd world sensibility either. Using sealed batteries is not
an excuse, it still needs to be somewhat 110.26 compliant to check
cell voltages and replace batteries. Just removing those old L
16s from the crawl space is nasty, dangerous work. My guess is
this would be subject to OSHA rules for hazardous, enclosed spaces
as well.<br>
</p>
<p>First plan to relocate the batteries, then lets have a discussion
on what brand is going to be used.<br>

have had good success using Full River AGM's in difficult

Vermont had no homeowner care for two months in the winter.
PV array became covered with snow and they had left their

became discharged and they were in temperatures well below
freezing. I was brought in to assess and service the
situation. I found these 6v 250AH AGM's with about 4 volts
