Growatt error 412: Temperature sensor connection is incorrect
Growatt error code 412 usually means the inverter has detected an issue with the temperature sensor connection or temperature sampling module. When this happens, your inverter may stop operating or reduce output to protect itself.
This is not a normal operating message and should not be ignored if it keeps appearing.
This type of fault may be linked to a loose or faulty temperature sensor connection, internal wiring issue, temperature sampling module fault, control board issue or another inverter-related fault.
Book a solar inverter check with e-Solar
If the code appears once and clears after a restart, your inverter may have recovered from a temporary sensor communication issue.
If Growatt error code 412 keeps returning, your solar output has dropped, or the inverter is not operating normally, it is worth having the system checked. Our Perth-based solar experts can inspect the inverter, review the fault history and help determine whether the issue is linked to the temperature sensor, sampling module, internal wiring or another inverter fault.
Contact e-Solar and let us know:
- The exact error code on the screen or app
- When the code appears
- Whether your solar production has dropped
- Your inverter model, if you know it
Do not open the inverter or attempt internal checks yourself. If the issue is persistent, a qualified technician may need to assess the temperature sensor connection, internal wiring, control board and system safety before recommending repair, warranty support or replacement.
