  • Why Buy From Us
  • The Rich Solar 1250W 48VDC-120VAC Solar Kit is a 48V off-grid system that pairs five MEGA 250 solar panels with a NOVA 6500S 6500W hybrid inverter and an ALPHA 5 PRO 51.2V 100Ah server rack LiFePO4 battery. Extension cables, Z-bracket mounting sets and a PV DC quick disconnect are included. It is designed for cabins, tiny homes, workshops, barns, remote properties and backup power.

    The 1250W array produces approximately 4.5kWh per day under 4 peak sun hours, and the 5.12kWh battery stores it for day and night use. The inverter delivers 6,500W continuous (13,000W surge) 120V pure sine wave power with a built-in 120A MPPT charger and accepts solar, battery, utility and generator inputs. The ALPHA 5 PRO is UL1973 and UL9540A certified and carries a 10-year warranty.

    Key Features

    • 1250W Solar Array: Includes five 250W monocrystalline solar panels, producing approximately 4.5kWh of energy per day under 4 peak sun hours.
    • 5.12kWh LiFePO4 Battery: Provides 51.2V 100Ah (5120Wh) of reliable energy storage for day and night use.
    • 6500W Hybrid Inverter: Delivers 6,500W continuous (13,000W surge) pure sine wave power with a built-in 120A MPPT charge controller, supporting solar, battery, utility, and generator inputs.
