What the 12K name means for system sizing
The RX-12K is rated for 11.4kW AC at 240V, with a 17.1kW maximum PV array at STC and four independent MPPT inputs. It uses a nominal 48V battery system (40–60V operating range) and includes a 200A transfer relay. Verify each string’s cold Voc, MPPT current, the selected battery’s BMS current, and utility/interconnection requirements in the manufacturer manual.
Explore the RUiXU 5.12kWh rack battery and RUiXU Lithi2-16 as battery options; confirm the exact inverter/BMS communication protocol and approved quantity before pairing.
RX-12K: hybrid inverter details
The RX-12K is a grid-interactive hybrid model with 11.4kW rated AC output at 240V, 120/240V backup output, up to 17.1kW STC PV array power, four MPPTs and a 600V maximum PV open-circuit voltage. Its 48V-class battery input operates over 40–60V. The SUNON12 is the separate off-grid model, so choose based on the actual grid and backup design.

Common questions
Is 17.1kW the AC output? No. It is the rated maximum PV array power at STC; rated AC output is 11.4kW at 240V.
Does any 48V battery work? No. RUiXU asks buyers using other battery brands to confirm the exact model with its technical support before installation.
Does RX-12K work with RUiXU Lithi2-16?
RUiXU explicitly lists its RX-CB-US conduit box for a Lithi2-16 battery paired with an RX-12K inverter. Its published battery communication guidance includes RX-12K setup. See the Lithi2-16 battery and manufacturer conduit-box listing for the exact model relationship.
That is a documented pairing, not a universal 48V-battery approval. Confirm current firmware, communication cable and protocol, battery count, current protection and installation instructions for the units being installed. RUiXU asks buyers to consult its technical support about other battery brands before treating them as compatible.
