RUiXU SUNON12 Off-Grid Inverter

Product Overview

The RUiXU SUNON12 is a 12 kW single/split-phase all-in-one off-grid inverter-charger for larger 48 V battery systems. Dual high-power MPPTs (up to 12 kW + 12 kW PV), 250 A charging, dedicated generator input, and a smart-load output target whole-cabin or small commercial off-grid loads.

Like other SUNON models it integrates inverter, solar MPPT, and AC charging with parallel capability (up to 6 units / 72 kW). This unit includes integrated breakers for key circuits and carries a longer manufacturer warranty period than the smaller SUNON models.

Best For

• Larger off-grid / backup systems needing 12 kW at 120/240 V
• High PV arrays on two MPPTs with 48 V battery banks up to 250 A charge
• Installs that need a dedicated generator port and smart-load output

Key Features

• 2 MPPTs; hybrid / mix charge up to 250 A
• Dedicated generator input (120 or 240 V selectable per documentation)
• Smart load output (~60 A class) with voltage/SOC/PV adaptive control
• Integrated breakers for INV input / GEN / Load / Smart load / Battery / PV
• Parallel 1–6 units; RS485 / CAN / USB / dry contact

Compatibility / Important Considerations

• Indoor only — plan a ventilated equipment space for fan-cooled operation.
• Not a grid-sell hybrid like Sol-Ark/Solis/GoodWe UL 1741 SB multimode units; design as off-grid / backup per RUiXU manuals.
• Confirm battery BMS protocol and cable sizing for 250 A charge paths.
• Professional installation required for high-current DC and AC conductors.
