48V Complete Off-Grid System · 30× Panel / 4× Battery / 2× Inverter
This complete off-grid system pairs a 12.3kW array of thirty MEGA 410 panels with a 20.48kWh ALPHA 5 PRO battery bank and two paralleled 6,500W hybrid inverters — producing roughly 44.3kWh per day, built for homes, cabins, farms, and commercial buildings that need to run fully off the grid.
410W each, 24V, 10-busbar Mono PERC cells — 12.3kW combined array. RS-M410
51.2V 100Ah (5,120Wh) each — 20.48kWh combined, rated for 7,000 cycles. RS-B5121P
6,500W each, paralleled for 13,000W continuous / 26,000W surge output. RS-H6548
The 12.3kW array produces roughly 44.3kWh daily under 4 peak sun hours, sized for real whole-property daily loads.
Four rack-mounted ALPHA 5 PRO batteries provide dependable overnight power and backup during outages.
Two paralleled hybrid inverters with dual 120A MPPT charge controllers each, supporting solar, battery, utility, and generator input.
Panel, battery, and inverter counts are pre-matched to simplify system design, installation, and long-term operation.
