2.2KW Complete Offgrid Solar Kit + 5K Sol-Ark Inverter + 20.48KW OMO Stack Lithium Battery +2.2KW Solar with Mounting Rails and Wiring

The 2.2KW Complete Offgrid Solar Kit + 5K Sol-Ark Inverter + 20.48KW OMO Stack Lithium Battery +2.2KW Solar with Mounting Rails and Wiring is designed for cabins, shops, RVs, and small off-grid structures seeking dependable power independence. This configuration pairs a Sol-Ark 5K split-phase 120/240V inverter with a 20.48kWh OMO heated stackable lithium battery bank. The bifacial solar array generates approximately 9,900 watts per day at 4.5 peak sun hours—well-suited for loads around 297 kWh per month. The system is expandable for future additions of both batteries and panels.
