Bill, I wouldn't, especially with FLAs. I have seen this situation here,
where the summer highs are similar, with a few homeowner/hack
installations and no, 60-cell modules will not finish the charge in hot
weather. Strings of three work just about perfect with modern charge
controllers, especially in winter, as they range high enough but well
below 150VDC limits.

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?
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.
