17KW Complete Offgrid Solar Kit - 15K Sol-Ark Inverter + 20.48KW OMO Stack Lithium Battery +17.6KW Solar with Ground Mount and Wiring

The 17KW Complete Offgrid Solar Kit - 15K Sol-Ark Inverter + 20.48KW OMO Stack Lithium Battery +17.6KW Solar with Ground Mount and Wiring is built for reliable, scalable off-grid power. It pairs a Sol-Ark 15K split-phase inverter with a 17.6kW bifacial solar array and a 20.48kWh OMO stackable lithium battery bank. Expect about 79,200 watts of solar production per day (at ~4.5 peak-sun hours). Ideal for small to mid-sized homes or cabins using around 2,376 kWh/month, the system is engineered to grow with additional panels or batteries.
