Check the number of PV modules connected in series in the PV string, and ensure that the PV string open-circuit voltage is no greater than the maximum operating voltage. After correctly configured the PV array, the inverter alarm disappears automatically.

What are Huawei inverter error codes?

Huawei inverter error codes occur due to grid disturbances, temperature issues, software issues, overcurrent, and other faults. Knowing each error code’s meaning will help you determine the appropriate solution to get the solar power system back to normal. Here’s a list of common Huawei inverter error codes culprits:

Why is my Huawei inverter NOT working?

An unrecoverable fault has occurred on a circuit inside the inverter. Turn off the AC output switch and DC input switch, and then turn them on after 5 minutes. If the fault persists, contact your dealer or Huawei technical support. Upgrade Failed or Software version un match. The upgrade does not complete normally. 1. Perform an upgrade again. 2.

Why is the end voltage lower than other PV strings?

String Current Back-feed. Only a few PV modules are connected in series in the PV string. Therefore, the end voltage is lower than that of other PV strings. Cause ID 1 = PV1, Cause ID 2 = PV2. – Check whether the PV modules connected in series in the PV string are enough.

How to replace a faulty Huawei inverter?

Huawei’s warranty replacement process is straightforward. First, the Hotline Team needs to confirm the replacement. Next, you’ll have to follow these steps: Step 1: Fill out a Faulty Tag form with the details about your faulty inverter and send it to the Hotline Team.

What if PV string polarity is less than 0.5 a?

If the number of modules connected in series to the PV string is less than those connected in series to the other PV strings attached in parallel, allow the PV string current to fall under 0.5 A, then turn off the DC switch and adjust the PV string polarity.
