RUiXU SUNON12 — 12kW of All-In-One Off-Grid Power

The RUiXU SUNON12 is a UL1741-certified single/split-phase off-grid inverter that delivers 12,000W of continuous pure sine wave power (18,000VA peak) at 120/240Vac. Built around 48V battery banks and equipped with dual MPPT solar inputs totaling 24,000W, it is a complete power core for off-grid homes, cabins, and backup power systems — and it scales with you, stacking up to 6 units in parallel for 72kW of combined output.
