12KW Complete Offgrid Solar Kit - 15K Sol-Ark Inverter + 15.36KW OMO Stack Lithium Battery +13.2KW Solar with Ground Mount and Wiring

The 12KW Complete Offgrid Solar Kit - 15K Sol-Ark Inverter + 15.36KW OMO Stack Lithium Battery +13.2KW Solar with Ground Mount and Wiring is a complete starter system for a fully independent off-grid home. It combines a 15.36kW OMO stackable heated lithium battery bank, a powerful 15K Sol-Ark pure sine split-phase inverter (120/240V), and a 13.2kW bifacial ground-mount solar array. Producing around 59,400 watts of energy per day based on 4.5 hours of sun, this kit is ideal for mid-sized homes using about 1,700 kWh per month and is designed to be scaled up with additional panels or batteries as your energy needs grow.
