What to do if Huawei SUN2000-15KTL-M5 displays phase wire short-circuited to PE?
If your Huawei Inverter indicates a phase wire short-circuited to PE, it means the impedance of the output phase wire to PE is low, or the output phase wire is short-circuited to PE. Check the impedance of the output phase wire to PE, find the low impedance point, and correct the fault.
What causes string current backfeed on Huawei Inverter?
String current backfeed on your Huawei Inverter means there aren't enough PV modules in series on the PV string, making its terminal voltage lower than other strings. To resolve this: 1. Check if the number of PV modules is less than in other strings. If so, wait for the PV string current to drop below 0.5 A, turn off all DC switches, and adjust the number of PV modules. 2. Check if the open-circuit voltage of the PV string is abnormal. 3. Check if the PV string is shaded.
What does unstable grid frequency mean on my Huawei Inverter?
An unstable grid frequency alarm on your Huawei Inverter means the rate of change in the power grid frequency doesn't meet local power grid code requirements. If the alarm occurs occasionally, it might be a temporary grid issue and the inverter should recover automatically. If the alarm persists, check whether the power grid frequency is within the acceptable range. If it is not, contact the local power operator.
What to do if Huawei Inverter shows device fault?
If your Huawei Inverter displays a device fault, it indicates an unrecoverable fault within the inverter. Turn off the AC output switch and DC input switch, wait 5 minutes, then turn them back on. If the alarm persists, contact your dealer or Huawei technical support. Ensure the PV string current is less than 1 A when performing these steps.
