Is 24v Charging the Same as 12v Charging?
With 24v charging on a 24v battery is everything the same as 12s except half the amps? Same charging profile, SOC vs time etc? Is 8.3 amps with 24v the same exactly as 16.6 amps on a 12v bank of the...

I am curious if Vmp of 30 will be enough in hot conditions.
I finally maybe got what smk is saying here. Elsewhere, somebody wondered if the Eco-Worthy's 42v limit was enough voltage spread for a 24v battery so that sounds similar. In this case from smk, the panel's voltage above 24v is in question not the controller's. (Vmp does not apply to PWM)
I am going for the Isc, so I am not concerned with the panel's voltage any more than I am when using a 12v panel.
Maybe I should be? 230w Voc when hot was 34v (37v rated) The 130s Voc is 22v and was 20.3v when hot. With PWM as intended to be used, panel voltage is battery voltage, so I don't know how that could affect getting Isc.
