About Huawei photovoltaic inverter is connected in reverse
Check whether the PV string is connected to the device in reverse polarity. If yes, wait until the PV string current decreases to below 0.01 A, set DC SWITCH to OFF, and adjust the PV string polarity.
Check whether the PV string is connected to the device in reverse polarity. If yes, wait until the PV string current decreases to below 0.01 A, set DC SWITCH to OFF, and adjust the PV string polarity.
If the DC input power cable is reversely connected, do not operate the 'DC SWITCH' and the positive and negative connectors immediately.

6 FAQs about [Huawei photovoltaic inverter is connected in reverse]
How to check if PV string polarity is reversed?
The PV string polarity is reversed. Check whether the PV string is reversely connected to the SUN2000. If yes, wait until the PV string current decreases below 0.5 A, set DC SWITCH to OFF, and adjust the PV string polarity. The number of PV modules connected in series to this PV string is insufficient.
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.
Why is my Huawei inverter NOT working?
However, this doesn’t mean that your inverter is faulty; issues could also arise from factors outside the system’s control or from other solar power system components. Huawei inverter error codes occur due to grid disturbances, temperature issues, software issues, overcurrent, and other faults.
Why does my sun2000 inverter alarm disappear?
After the PV array is correctly configured, the inverter alarm disappears. The PV string power cable arcs or is in poor contact. Check that the PV string power cable does not arc and is in good contact. The PV string polarity is reversed. Check whether the PV string is reversely connected to the SUN2000.
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:
How does a solar inverter work?
A solar inverter can quickly detect issues disrupting a solar PV system and signal you using corresponding error codes. The primary function of solar inverters is power conversion (DC electricity to AC output). But the current line of inverters on the market does more than that.
