What to do if Huawei SUN2000 Inverter reports abnormal PV module configuration?
- JJeremy VillaAug 30, 2025
An abnormal PV module configuration error on your Huawei Inverter means the PV string power or the number of optimizers connected in series in a PV string exceeds the upper threshold. It could also mean the number of optimizers connected in series in a PV string is less than the lower threshold, the PV string output is reversely connected, or the output of some optimizers in the PV string is reversely connected. Check whether the total number of PV modules, number of PV modules in a PV string, and number of PV strings meet requirements and whether the PV module output is reversely connected.
