SUNON7.2 · Buyer decision facts
RUiXU SUNON7.2 | 7.2kW 48V Off-Grid Inverter
The SUNON7.2 is a 7,200W off-grid inverter for a nominal 48V battery system. Its configurable 120/240V output and two MPPT inputs support a planned split-phase solar installation.
Each MPPT supports up to 4.5kW PV, for 9kW combined. Respect the 500V PV Voc ceiling and 16A input limit per MPPT. Confirm the chosen battery’s 40–60V operating range, BMS current and communication protocol.
For a larger off-grid design, compare the SUNON12; for a hybrid grid-interactive design, see the RX-12K.
SUNON7.2: what to check before installation
This off-grid model supplies 7,200W continuous AC output and has two PV MPPT inputs. RUiXU lists up to 4,500W per MPPT, 16A input current per MPPT, and a 500V maximum PV open-circuit voltage. Its IP20 enclosure is for indoor installation.
What RUiXU lists in the standard package
- SUNON7.2 inverter
- 200 cm CAT6 battery communication cable

Common questions
Can I connect a 9kW solar array? The two MPPTs total 9kW of published PV input power, but every string must also stay within its MPPT current, operating-voltage window and cold-corrected 500V Voc limit.
Is this the same as RX-12K? No. SUNON7.2 is an off-grid inverter; the RX-12K is a grid-interactive hybrid design.
