Overview
Five MEGA 250W panels, a 6.5kW 48V off-grid inverter (RS-H6548S) and one ALPHA 5 PRO 51.2V 100Ah server rack battery that stores 5,120Wh. The inverter gives 6,500W of 120VAC pure sine wave power and accepts up to 8,000W of solar input, so there is room to add panels later. Rich Solar estimates about 4.5kWh a day from the panels with 4 peak sun hours.
Who it's for
Tiny homes, cabins and RVs that want to start small on a 48V system and grow it over time. The Solar System Sizer can show how much panel and battery your loads need.
