Solis alarm 1031: DSP initialising fault
Solis alarm code 1031 usually means the inverter has detected a DSP initialising fault. DSP refers to the digital signal processor, which helps manage the inverter’s internal control and power conversion functions.
Alarm code 1031 may appear as:
- INI-FAULT
When this happens, the inverter may fail to start properly, stop exporting power or disconnect as a protective response.
This is not a normal operating message and should not be ignored if it keeps coming back. A DSP initialising fault may be linked to internal inverter control issues, firmware behaviour, startup faults, internal hardware problems or another inverter-related fault.
Let e-Solar check your inverter and startup behaviour
If the alarm appears once and clears after a restart, the inverter may have recovered from a temporary startup issue.
If Solis alarm 1031 keeps returning, it is worth having the system checked. Our Perth solar experts can inspect the inverter, review the fault history and help determine whether the issue is linked to inverter startup behaviour, firmware, internal components 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 inverter diagnostics, firmware status and internal components before recommending repair, warranty support or replacement.
