Possible Causes
Incorrect wiring to external meter, Wrong meter type or protocol configured, Misconfigured current limits, Faulty RS-485 or control input on charger
How to Fix / Troubleshooting
Safety: De-energize control circuits before rewiring.
- Check wiring diagram: Compare actual wiring between the go-e Charger and the external meter/controller with the official go-e documentation.
- Verify meter configuration: In the app, select the correct meter model and communication protocol. Ensure addresses and baud rates match the external device.
- Test meter independently: Confirm that the external meter is working and providing valid data using a separate Modbus or API tool.
- Disable load management temporarily: Turn off dynamic load management in settings. If charging then behaves normally, the issue is in the external system or interface.
- Inspect RS-485 interface: If all external components are correct, the charger’s RS-485 or control input may be defective and require board replacement.
