RUiXU SUNON3.6 Off-Grid Inverter

Product Overview

The RUiXU SUNON3.6 is a 3.6 kW all-in-one off-grid / hybrid-capable inverter-charger for 48 V battery systems. It integrates a pure sine wave inverter, single MPPT solar charger, and AC charger so cabins, workshops, or small homes can run from solar, grid/generator, and batteries without a separate charge controller.

Output is 120 VAC single-phase. Two or more units can be paralleled (up to 6) to build higher capacity or form split-phase / three-phase arrangements per RUiXU parallel rules.

Best For

• Small off-grid or backup systems needing 3.6 kW / 120 V output

Compatibility / Important Considerations

• Indoor only (IP20) — not for outdoor unprotected mounting.
• 120 V output only on a single unit; follow RUiXU parallel instructions for 120/240 V.
• Confirm closed-loop BMS settings if using RUiXU or third-party lithium batteries.
• Professional installation recommended for AC/DC interconnection and grounding.
