2.2KW Complete Offgrid Solar Kit + 5K Sol-Ark Inverter + 10.24KW OMO Stack Lithium Battery +2.2KW Solar with Mounting Rails and Wiring

The 2.2KW Complete Offgrid Solar Kit + 5K Sol-Ark Inverter + 10.24KW OMO Stack Lithium Battery +2.2KW Solar with Mounting Rails and Wiring is a reliable starter system for cabins, shops, RVs, and small off-grid spaces. It pairs a Sol-Ark 5K split-phase inverter (120/240V) with an OMO 10.24kWh stackable heated lithium battery bank to deliver 10,240 usable watt-hours. The bifacial solar array generates about 9,900 watts per day at 4.5 peak sun hours—well-suited for sites using roughly 297 kWh per month. The system is designed to scale with future panels or battery additions.
