What does System Fault mean on my Huawei SUN2000-12KTL?
A System Fault on the Huawei Inverter indicates an unrecoverable fault has occurred on a circuit inside the inverter. Flip the DC SWITCH on the inverter to OFF, wait 5 minutes, and then flip the DC SWITCH to ON. Check if the fault is rectified.
What to do if Huawei SUN2000-12KTL Inverter Firmware Upgrade Failed?
A Firmware Upgrade Failed error on a Huawei Inverter means the upgrade process was incomplete. Upgrade again.
How to fix DC Over Voltage on Huawei SUN2000-12KTL Inverter?
If your Huawei Inverter SUN2000 is showing a DC Over Voltage alarm, it means the voltage from your PV modules is too high. To fix this, you need to reduce the number of PV modules connected in series for each PV string (1 and 2, 3 and 4, or 5 and 6) until the open-circuit voltage is at or below the inverter's maximum input voltage. Once you've adjusted the PV array configuration, the SUN2000 alarm should disappear.
Why does my Huawei Inverter show Abnormal Grid Voltage?
If your Huawei Inverter is showing an Abnormal Grid Voltage error, it could be due to a couple of reasons. If the alarm seems to be a one-time occurrence (Cause ID = 4), it might be due to a temporary issue with the power grid, and the SUN2000 should automatically return to normal operation once the grid stabilizes. However, if the grid-tied point voltage is consistently too high (Cause ID = 16/19/26), you should contact your local power operator to investigate the grid conditions.
