EnergyFaults — error codes and troubleshooting for energy devices

Communication error

The battery system and the inverter or gateway have stopped exchanging data.

Common causes

  • CAN or RS485 cable loose between battery and inverter
  • Address or protocol mismatch after a firmware update
  • One device unpowered
  • Termination or shielding problem

Safe checks

  1. 1Check the status indicators on each device and note every code shown.
  2. 2Confirm all devices have power.
  3. 3Do not re-terminate or rewire communication cabling yourself.
  4. 4Report the codes on both devices to your installer.

When to call a technician

Call a qualified technician if the device repeats the fault after a manufacturer-approved restart, shows a burning smell, has damaged or discoloured wiring, or if the symptom involves the battery, inverter power stage or any sealed high-voltage component.
