Solis alarm 1038: 12V power supply fault
Solis alarm code 1038 usually means the inverter has detected a fault with its internal 12V power supply. This internal supply supports inverter control, monitoring and operating functions.
Alarm code 1038 may appear as:
- 12Power-FAULT
When this happens, the inverter may fail to start, stop producing power or disconnect from the grid as a protective response.
This type of fault may be linked to internal power supply issues, inverter hardware faults, control board behaviour, component failure or another internal inverter problem.
Let e-Solar check your inverter and internal power supply
If the alarm appears once and clears after a restart, the inverter may have recovered from a temporary internal condition.
If Solis alarm 1038 keeps returning, it is worth having the system checked. Our Perth-based solar team can inspect the inverter, review the fault behaviour and help determine whether the issue is linked to the internal 12V power supply, control circuitry, inverter hardware 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 technician may need to assess internal inverter diagnostics and advise whether repair, warranty support or replacement is required.
