RUiXU SUNON7.2 Off-Grid Inverter

Product Overview

The RUiXU SUNON7.2 is a 7.2 kW single/split-phase all-in-one off-grid inverter-charger for 48 V batteries. Dual MPPTs, higher charge current (150 A), and 120/240 V output make it a mid-size option between the SUNON3.6 and SUNON12.

It combines inverter, MPPT solar charging, and AC charging with timed charge/discharge controls and optional Wi-Fi monitoring. Up to six units can stack for larger off-grid or backup plants.
