Hello,
With my goal to build a 5khw 48V system, I am looking into using 2 of these 24V LiFePO4 Powerwalls with an MPP Solar 5000w 48vdc 120v/208V/240V Split phase Solar inverter 80A Dual MPPT charger. The reason I am considering 48V is because of lower cost and better efficiency. Since, I will be living in a cloudy, rainy, snowy area with 157 days of sun per year, I am looking into the Monocrystalline higher-efficiency panels (from 20% to 22%).
However maybe I am missing something here. I see panels like any appliance are rated at specific voltages. So my question. Does this mean I need 48V solar panels? If yes, are these a lot more expensive than 12v or 24v panels? And can anyone recommend a good deal?
Thanks.
