30KW Complete Offgrid Solar Kit + EG4 18kPV + 2x 14.3KW 48V EG4 Lithium Indoor Wall Battery + 30.8KW Solar with Roof Mounting Rails and Wiring

The 30KW Complete Offgrid Solar Kit + EG4 18kPV + 2x 14.3KW 48V EG4 Lithium Indoor Wall Battery + 30.8KW Solar with Roof Mounting Rails and Wiring includes dual EG4 18kPV hybrid inverter/chargers, two 14.3kWh EG4 Indoor Wall Batteries (28.6kWh total usable storage), and a high-output 30.8KW bifacial solar array designed for full off-grid residential and agricultural applications. Producing approximately 138,600 watts (≈138.6kWh) per day based on 4.5 peak-sun hours, this system supports homes using around 4,158 kWh per month. Fully expandable for future panel or battery additions, it provides a powerful backbone for complete energy independence.
