I am working on ironing out my first design. I have a 840Ah battery bank used to supply two 5kW MultiPlus-II’s configured in parallel. The goal for now is to charge the batteries from the grid overnight.
My question is, with the inverters in parallel, do I need two separate 120V AC power sources (one for each inverter) to charge the batteries? I would like to use both inverters to charge the batteries faster. I am using SEPLOS LiFePO batteries.
