Configuring the meter in the mobile application
Note: You can use two meters with different addresses. Both meters share the same settings in the installer menu.
- Make sure your charger firmware and application are updated to the latest version (see Release notes: Firmware and the app for iOS / Android).
- Enter the Installer menu, select Load Balancing, then Modbus RTU.
- If the charger does not recognise the meter, go to Manual Setup and choose your meter model from the presets, or enter the values from the RS-485 parameters table manually.
Once the meter is successfully configured, press Connect. You will receive a confirmation screen and the status will change. Possible statuses:
- Connected – the meter is configured correctly.
- Disconnected – a wrong parameter value is set on the charger, or the meter is not wired correctly.
- Wrong type – the meter configuration does not match the connected meter.
- Not supported – the connected meter is not compatible with the installation.
For detailed settings, refer to the energy meter's official documentation.
