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

The 30KW Complete Offgrid Solar Kit + EG4 18kPV + 2x 14.3KW 48V EG4 Lithium Indoor Wall Battery + 30.8KW Solar with Ground Mount and Wiring pairs dual EG4 18kPV hybrid inverters with two 14.3kWh 48V EG4 Lithium Indoor Wall Batteries (28.6kWh total) and a high-output 30.8KW bifacial solar array on an IronRidge ground-mount. Designed for full off-grid homes and farms, it produces about 138,600 watts (≈138.6 kWh) per day based on 4.5 peak-sun hours and supports usage around 4,158 kWh per month. The system is expandable, and the EG4 platform lets you grow with additional panels or storage over time.
