SMA error 6305: Interference of device
SMA inverter error code 6305 usually means the inverter has detected an internal device interference issue during self-diagnosis.
This type of error can relate to internal inverter behaviour, hardware interference, firmware issues, communication problems or another fault affecting the inverter’s ability to operate safely.
When this happens, the inverter may stop producing power or disconnect from the grid as a safety response.
Let e-Solar check your inverter and system operation
If SMA error code 6305 appears once and clears by itself, the inverter may have recovered from a temporary internal condition.
If the code keeps returning, your solar production has dropped, or the inverter is not operating normally, it is worth having the system checked. Our Perth-based solar team can inspect the inverter, review fault behaviour and help determine whether the issue is linked to internal inverter hardware, firmware, communication or another system 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 testing yourself. If the issue is persistent, a qualified solar technician may need to assess inverter diagnostics, internal components and system operation before recommending repair, warranty support or replacement.
