60 Cell Panel vs 24v Bank MPPT and PWM UPDATE
UPDATE--results with MPPT posted 1 June. Got a chance to run this test today with no clouds but a slight haze up high so not quite 1000 insolation, showed as 8.93Isc vs rated 9.0, however that did ...
Forum Discussion
The question arose during a thread recently, whether a 60 cell panel could get a bank to 30v in the same way as a 36 cell panel could a 12v bank, where a 32 cell panel was proven inadequate with a 12v bank.
This test was to see if indeed a 60 cell panel would be able to recharge a 24v bank, and it turns out it can.
There may be issues at lower light, lower voltage where a 72 cell panel would "outshine" (ha! ) the 60 , but this is what happened today.
I need to see if there is any advantage in going PWM for high panel temps, but that is a different "issue" to be tested for in July.
