SUNON12 · Buyer decision facts
RUiXU SUNON12 | 12kW 48V Off-Grid Inverter
The SUNON12 supplies 12,000W rated AC output for an off-grid 48V battery system, with 120/240V split-phase capability. It is a different inverter class from the grid-interactive RX-12K hybrid.
Its two MPPTs list up to 12kW PV each, with a 500V open-circuit ceiling and 32A per input. Size strings from cold-corrected Voc and check the 40–60V battery range, BMS current, and generator or transfer wiring.
For a smaller off-grid system, compare the SUNON7.2; for hybrid use, see the RX-12K.
SUNON12: what to check before installation
SUNON12 has 12,000W rated AC output for an off-grid 48V-class battery system. Its two MPPT inputs each list up to 12kW PV power and 32A input current, with a 500V maximum PV open-circuit voltage. Its IP20 enclosure is for indoor installation. Do not treat the 24kW combined PV input figure as AC output.

Common questions
Can it export to the grid? SUNON12 is RUiXU’s off-grid model. For a grid-interactive installation, review the RX-12K hybrid inverter and local interconnection requirements.
Can I connect any two 12kW arrays? No. Each MPPT also has a 32A input limit and 500V maximum open-circuit voltage; string design must follow the manual and cold-weather correction.
