Solis alarm 1037: DC injection component too large
Solis alarm code 1037 usually means the inverter has detected that the DC component within the AC output current is too high. In simple terms, the inverter has identified an abnormal current condition while converting solar power into grid-compatible AC power.
Alarm code 1037 may appear as:
- DCInj-FAULT
When this happens, the inverter may stop exporting power or disconnect from the grid as a protective response.
This is not a normal operating message and should not be ignored if it keeps coming back. It may be linked to inverter output behaviour, grid conditions, internal power conversion faults, firmware behaviour or another inverter hardware issue.
Let e-Solar check your inverter and output current
If the alarm appears once and clears after a restart, the inverter may have recovered from a temporary output current condition.
If Solis alarm 1037 keeps returning, it is worth having the system checked. Our Perth-based solar team can inspect the inverter, review inverter output behaviour and help determine whether the issue is linked to DC injection, grid conditions, inverter hardware, firmware or wider system conditions.
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 electrical testing yourself. If the issue is persistent, a qualified technician may need to assess inverter output, internal diagnostics and whether the inverter needs repair, firmware support or replacement.
