5. Troubleshooting

In this section:

If the system exhibits strange behaviour, check the following:

  1. Current sensor orientation: Ensure the current transformers are oriented correctly. The arrow on the CT should point from the generator to the contactor, matching the direction indicated in the Wiring diagram.

  2. Current sensor connections: Verify that the current sensors are connected to the correct units: L1 to the L1 unit, L2 to the L2 unit, and so on.

  3. Wiring placement: Ensure the current sensor wires are not routed too close to AC or signal wires.

Known issues:

  • VRM kWh counters: The VRM kWh counters may display incorrect readings. This will be addressed in an upcoming version of Venus OS.

  • VictronConnect App: The VictronConnect app cannot be used for system configuration and current sensor settings. Use VEConfigure 3 and VE.Bus System Configurator software instead.
