Fault Code Reference

Battle Born BMS has disconnected the battery due to a protection event.

MRBF terminal fuse is tripping under normal operation.

Solar panel input is shorted. No power generation.

REDARC DC-DC charger has detected an input voltage fault. Charging disabled.

REDARC charger has entered thermal protection mode. Output reduced.

Both alternator and solar inputs are active simultaneously — REDARC is managing priority.

REDARC Battery Monitor cannot communicate with the shunt sensor.

BCDC cannot detect battery. No charging will occur.

Battery voltage has exceeded the maximum limit. Charging stopped.

Battery voltage has dropped below the minimum threshold.

Solar panel array voltage exceeds maximum PV input limit.

Solar panel positive/negative connections are reversed.

Internal temperature of Renogy Rover has exceeded safe operating limit.

Solar panel voltage exceeds controller limit. May damage controller if not addressed.

Battery voltage exceeds safe charging limit. Charging suspended.

The battery temperature sensor has detected a temperature exceeding safe charging limits.

Battery voltage exceeds maximum safe limit. Charging has been paused.

Internal temperature of MPPT controller has exceeded safe operating limits. Output disabled.

Battery has not reached absorption voltage within the configured bulk time limit.

The PV or battery terminal temperature is too high. Immediate safety risk.

The PV panel voltage exceeds the maximum input voltage of the controller.

Solar input has been shut down because battery voltage is dangerously high.

Safety shutdown of PV input failed. Internal relay may be damaged.

Communication with the connected BMS has been interrupted.

Inverter shut down due to battery voltage dropping below minimum threshold.

Charger side of MultiPlus has shut down due to over-voltage condition.

The inverter output load exceeds its continuous rated capacity.

Inverter has shut down due to excessive internal temperature.

Panel voltage exceeds MPPT maximum input voltage. Common in cold weather when Voc rises above rated limits.

Battery voltage below minimum threshold. System may not start or charge properly.

Battery voltage exceeds maximum charge voltage. Risk of battery damage.

MPPT internal temperature too high — charge rate reduced automatically.

Inverter output exceeds rated capacity. Automatic shutdown to prevent damage.

Remote control function is disabled. Cannot control device remotely.
