<DIV><BR></DIV>Those HUP batteries are still under warranty and you very well
may have a free cell waiting for you, give Rob or Jean a call at NWES and run it
past them. They offer 1st rate CS and should take good care of you. You won't
get much for used batteries so I would be inclined to keep them in service even
though 4 strings in parallel is not ideal. I've had reasonable luck with 4
strings paralleled by getting my battery/inverter cables all over the bank, at
the least put 1/2 of your inverters across 2 strings and the other 1/2 on the
remaining 2 strings (still parallel all 4 strings).<BR><BR>You never mentioned
an EQ cycle either, with that limited Absorption time it should happen at least
every 6 weeks. <BR><BR><BR>From the Solar, Wind and Hydro powered office of Jeff
