What causes Grid Undervoltage on a Huawei SUN2000-50KTL-JPM0?

  If your Huawei Inverter shows a 'Grid Undervoltage' error, it means the grid voltage is too low. If this happens briefly, it might be a temporary grid issue, and the SUN2000 should recover automatically. If it happens often, check if the grid voltage is within the acceptable range; if not, contact your local power operator. If the voltage is within range, you might need to adjust the undervoltage protection threshold with the power operator's consent. Also, check the AC circuit breaker and AC output power cable if the problem continues.

Why does my Huawei Inverter show Grid Overvoltage?

  If a 'Grid Overvoltage' alarm appears on your Huawei Inverter, it means the grid voltage is too high. First, check if the grid connection voltage exceeds the upper threshold and contact the local power operator if it does. If you have confirmed the overvoltage and have consent from the power operator, you can modify the overvoltage protection threshold. Also, ensure the peak grid voltage does not exceed the upper threshold.

How to fix Huawei Inverter High String Input Voltage?
- R
  Rachel MitchellAug 23, 2025
  If your Huawei Inverter displays 'High String Input Voltage', it indicates the PV array is incorrectly configured. Too many PV modules are connected in series, causing the PV string open-circuit voltage to exceed the SUN2000's maximum operating voltage. Reduce the number of PV modules connected in series until the PV string open-circuit voltage is within the limit. The alarm should then stop.
