25KW Complete Offgrid Solar Kit - 2x32kWh OMO 48V Freedom Series Lithium Battery + 2x 15K Sol-Ark Inverter +26.4KW Solar with Mounting Rails and Wiring

The 25KW Complete Offgrid Solar Kit - 2x32kWh OMO 48V Freedom Series Lithium Battery + 2x 15K Sol-Ark Inverter +26.4KW Solar with Mounting Rails and Wiring is designed for full off-grid home power. This system includes two 15K Sol-Ark hybrid inverters, a massive 64,000-watt (64 kWh) lithium battery bank, and a high-output 26.4 kW bifacial solar array. Producing approximately 118,800 watts per day based on 4.5 hours of peak sunlight, it is ideal for larger homes using around 3,500 kWh per month. The system is fully expandable, allowing future additions of both batteries and solar panels.
