70KW Complete Offgrid Solar Kit + 4x 15K Sol-Ark Inverter +70.4KW Solar with Ground Mount and Wiring

The 70KW Complete Offgrid Solar Kit + 4x 15K Sol-Ark Inverter +70.4KW Solar with Ground Mount and Wiring is engineered for large homes, farms, and high-demand off-grid properties. Producing approximately 316,800 watts per day (based on 4.5 hours of sun), this system is ideal for locations using around 9,500 kWh per month. Designed for long-term scalability, it can be expanded with additional solar panels or batteries as energy needs grow.

This kit can operate with or without a battery. A 48V battery bank may be added at any time for additional storage.
