<p>I've been on hold with OB for about 40 minutes now and I need to
know if 2 SW PVs with a Voc of 39.9 and a Vmpp of 31.3 will do an
effective job of charging a 48 volt LA battery especially with
temps of 95 degrees. Anybody have experience with this or
similar, Appreciate the feedback. It just seems I'm a little low
in Vmpp if I want to equalize when its hot. Will it be even more
questionable in 10 years as PVs age?<br>
</p>
<p>OB did just pickup only to tell me I need Java for the string
sizing tool and he can't help me with this configuration.</p>

<p>If it's a 48V system, you might also look at Blue Ion LiFePo
batteries and eliminate the lead for good. I just installed my
first set and consider it a game changer.<br>
