Re: Combiner box - Amps?
Welcome to the forum JJ, Can you tell me the Vmp/Imp (and the Voc/Isc too) of the panels? Basically... If you have (for example) Vmp~19 volt panels and Imp~6 amps.. .You have P=V*I=114Watt panels. Th…1 · -
Re: Charge rate on a hot day
For connecting panels in series, you want to "match" the Imp (current maximum power) to within 5% or better (best) or at least within 10% for optimum power from the array (I.e., a 10 amp an…1 · -
Re: Charge rate on a hot day
Max voltage of 150 VDC means do not exceed. Basically, cold/sub freezing days, Voc, etc. means array voltage is higher than Voc-std (standard temperature/test conditions)... If you are in the norther…1 · -
Re: few questions about solar power....
The "optimum" solar only A/C system probably uses a "smart VFD" and "solar aware" controller+software. Basically, only "turn on" when there is enough solar ene…1 · -
