What to do if Huawei Inverter upgrade failed?
If the Huawei Inverter software upgrade has failed, here's what you can do: 1. When the sunlight is normal, try the optimizer upgrade again. 2. If the fault persists, contact your installer.
How to fix Huawei MERC-1300W-P Inverter upgrade failed?
If the Huawei Inverter upgrade failed, when the irradiance is normal, perform the optimizer upgrade again.
Why does my Huawei Inverter show input overvoltage?
The Huawei Inverter might be showing an input overvoltage because of optimizer input overvoltage. To resolve this, check whether the open-circuit voltage of the PV module exceeds the maximum input voltage of the optimizer.
What to do if Huawei Inverter shows output backfeed?
If your Huawei Inverter is showing an output backfeed, here's what you can do: 1. Check if PV modules are shaded when PV strings are connected in parallel. 2. If the fault persists, contact your installer.
What to do if Huawei Inverter is overtemperature?
If your Huawei Inverter is showing an overtemperature warning, it means that the optimizer internal temperature is too high. Here's how to address it: 1. Check the ventilation and ambient temperature around the optimizer. If ventilation is poor or the ambient temperature is too high, improve ventilation and heat dissipation. 2. If ventilation and temperature are normal, contact your installer.
What to do if Huawei MERC-1300W-P Inverter output terminal is overtemperature?
If the output terminal temperature of some optimizers is abnormal, contact your installer to replace the faulty optimizer and the optimizer connected to the short output cables of the faulty optimizer. The cause is that the output terminal temperature of some optimizers is abnormal.
What to do if Huawei Inverter has internal hardware fault?
If your Huawei Inverter is showing an internal hardware fault, contact your installer. This indicates that an internal fault has occurred in an optimizer.
How to fix Huawei MERC-1300W-P Inverter overtemperature protection?
If your Huawei Inverter shows an overtemperature protection warning, it means the optimizer internal temperature is too high. You should: 1. Check the ventilation and ambient temperature at the optimizer installation position. If the ventilation is poor or the ambient temperature exceeds the upper threshold, improve the ventilation and heat dissipation. 2. If the ventilation and ambient temperature are normal, contact your installer.
What to do if Huawei MERC-1300W-P shows output terminal overtemperature?
If your Huawei Inverter reports output terminal overtemperature, it means the output terminal temperature of some optimizers is abnormal. Contact your installer to replace the faulty optimizer and the optimizer connected to the short output cables of the faulty optimizer.
