4.4KW Complete Offgrid Solar Kit + 6K EG4 6000XP Inverter + 2x 5.12KW OMO 48V Patriot Lithium Battery + 4.4KW Solar with Roof Mounting Rails and Wiring

The 4.4KW Complete Offgrid Solar Kit + 6K EG4 6000XP Inverter + 2x 5.12KW OMO 48V Patriot Lithium Battery + 4.4KW Solar with Roof Mounting Rails and Wiring is a capable starter system for cabins, shops, RVs, garages, and small off-grid homes. Paired with 2 × 5.12kWh OMO 48V Patriot wall-mounted lithium batteries (10.24kWh total) and a 4.4KW bifacial solar array, it delivers about 19,800 watts per day assuming 4.5 peak sun hours—ideal for sites using around 594 kWh per month. The kit is designed to scale with additional panels or batteries as needs grow.
