25KW Complete Offgrid Solar Kit + EG4 18kPV + 2x 32KW OMO 48V Freedom Series Lithium Battery + 26.4KW Solar with Ground Mount and Wiring

The 25KW Complete Offgrid Solar Kit + EG4 18kPV + 2x 32KW OMO 48V Freedom Series Lithium Battery + 26.4KW Solar with Ground Mount and Wiring is designed for complete off-grid homes that need serious, reliable power. With 64,000W of usable lithium battery capacity and a 26,400W bifacial solar array, this system can produce around 118,800W of energy per day based on 4.5 hours of peak sun. It’s an excellent choice for larger homes using about 3,500 kWh per month and is built to be easily scaled with additional panels or batteries as your energy needs grow.
