Solis alarm 1048: IGBT overcurrent
Solis alarm code 1048 usually means the inverter has detected overcurrent involving its internal IGBT components. IGBTs are key power conversion components that help convert solar energy into usable AC power.
Alarm code 1048 may appear as:
- IGBT-OV-I
When this happens, the inverter may stop operating or disconnect as a protective response.
This is not a normal operating message and should not be ignored if it keeps coming back. IGBT overcurrent may be linked to internal inverter hardware, abnormal current conditions, power conversion faults, grid disturbance or another electrical issue affecting inverter operation.
Let e-Solar check your inverter and internal power components
If the alarm appears once and clears after a restart, the inverter may have recovered from a temporary overcurrent condition.
If Solis alarm 1048 keeps returning, it is worth having the system checked. Our Perth-based solar team can inspect the inverter, review the fault history and help determine whether the issue is linked to inverter hardware, internal power components, grid conditions or wider system behaviour.
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 and determine whether repair, warranty support or replacement is required.
