Then there is no choice. With 12x2v cells, you will have a single series string of ~700ah @ 24v. There is no parallel option.2 · -
Re: Advice for Panel and Interface for Simple System
IMHO, the main reason to spring for an mppt controller is if the array is far away from the controller. If so, it makes more sense to put panels in series. Running at higher series voltages keeps cur…1 ·
