What to do if my Huawei Inverter showing Overtemperature?
- A
  Anthony SchwartzAug 26, 2025
  If your Huawei Inverter is showing an Overtemperature warning, it indicates that the unit is installed in a location with poor ventilation, the ambient temperature is too high, or the SUN2000 is not working properly. You should check the ventilation and ambient temperature of the SUN2000 installation position. If the ventilation is poor or the ambient temperature exceeds the upper threshold, improve the ventilation and heat dissipation.

Why is my Huawei Inverter showing High String Input Voltage?
- H
  heatherrussellAug 25, 2025
  If your Huawei Inverter displays a High String Input Voltage error, it's because the PV array is not properly configured. Specifically, too many PV modules are connected in series, causing the open-circuit voltage to exceed the SUN2000's maximum operating voltage. To resolve this, check the serial connection configuration of the PV string and ensure that the PV string open-circuit voltage does not exceed the SUN2000's maximum operating voltage. After correcting the PV array configuration, the alarm should disappear.
