48V Complete Off-Grid System · 16× Panel / 3× Battery / 1× Inverter
This complete off-grid system pairs a 6,560W array of sixteen MEGA 410 panels with a 15.36kWh ALPHA 5 PRO battery bank and a 6,500W hybrid inverter — producing roughly 23.6kWh per day, built for homes, cabins, workshops, farms, and remote properties running off the grid.
410W each, 24V, 10-busbar Mono PERC cells — 6,560W combined array. RS-M410
51.2V 100Ah (5,120Wh) each — 15.36kWh combined, rated for 7,000+ cycles. RS-B5121P
6,500W pure sine wave output with a built-in 120A MPPT charge controller. RS-H6548
The 6,560W array produces roughly 23.6kWh daily under 4 peak sun hours, sized for full-property daily loads.
Three rack-mounted ALPHA 5 PRO batteries provide dependable overnight power and backup during outages.
The 6,500W hybrid inverter includes a 120A MPPT charge controller supporting solar, battery, utility, and generator input.
Panel, battery, and inverter counts are pre-matched to simplify system design, installation, and long-term operation.

Yes — the NOVA 6548 has a built-in 120A MPPT controller, so no separate charge controller hardware is needed for this kit.
15.36kWh combined from three 5,120Wh ALPHA 5 PRO batteries, each rated for 7,000+ deep cycles and expandable up to 30 units in parallel.
Each ALPHA 5 PRO has an integrated 150W heater that activates automatically below 41°F and shuts off once the battery warms past 50°F; charging locks out entirely below 32°F.
Yes — the inverter supports up to 8,000W of solar input in total, above the 6,560W included, and the battery system can scale up to 30 units in parallel.
Given the scale of this system — a 6,500W inverter, a 15.36kWh battery bank, and a 6,560W solar array — installation should be handled by a qualified, licensed electrician or solar installer familiar with your local code.
