11 questions about the Classic 150.

i think you might be misunderstanding boB somewhat as he was referring to the temperature of the pvs, for the cold of winter will allow a rise in voltage and a slight overall increase in power as compared to the high heats of summer which will lower the voltage and power some for the pvs' output. it has nothing to do with your inside temperatures and will not add to the heat in your home. for example, if one has an array output in the summer of say 149.85v and a cc that is rated for 150v max input that the winter voltages would exceed that 150v threshold and it would not operate if it's a classic 150. nobody should design that closely to the cc max rating anyway, but the classic can handle over-voltages by a factor of the battery voltage without damage, but it will not operate beyond its rated voltage.

as to the pvs operating at a vmp around 37v and keeping them paralleled that it does work out fine for a 12v battery bank as that is 1 up from 12v.
