Solis alarm 1032: Overtemperature
Solis alarm code 1032 usually means the inverter has detected excessive internal temperature. This commonly relates to the temperature near the inverter’s internal power components.
Typically:
- 90°C for 1P inverters
- 115°C for 3P inverters
Alarm code 1032 may appear as:
- OV-TEM
When this happens, the inverter may reduce output, stop exporting power or shut down temporarily to protect itself from heat-related damage.
Overtemperature can be caused by direct sun exposure, poor ventilation, high ambient temperature, blocked airflow, a faulty temperature sensor, a loose internal temperature probe connection or another internal cooling issue.
In Perth summers, heat-related inverter alarms can become more common, especially when the inverter is installed in direct sunlight or a poorly ventilated location.
Let e-Solar check your inverter and ventilation
If the alarm appears once during very hot conditions and clears after the inverter cools down, it may have been a temporary heat-related protection response.
If Solis alarm 1032 keeps returning, it is worth having the system checked. Our Perth-based solar team can inspect the inverter location, check ventilation and help determine whether the issue is linked to heat exposure, blocked airflow, sensor faults, inverter mounting or internal temperature 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 cleaning or repairs yourself. If safe to do so, keep the area around the inverter clear and check that airflow is not obviously blocked. If the issue is persistent, a qualified technician may need to inspect cooling performance, temperature behaviour and system operation.
