Description: Grid-tied/Off-grid Controller Abnormal. The inverter fails to communicate with the Smart Backup Box. An unrecoverable fault occurs on a circuit inside the Smart Backup Box. What to do: 1. Send a shutdown …
If optimizers are configured for all PV modules, the PV system can perform a rapid shutdown to decrease the output voltage to below 120 V within 15s and to below 30 V within 30s. Perform the following steps to trigger a rapid shutdown: Method 1: Turn off the AC switch between the inverter and the power grid.
Turn off the AC output switch and then the DC input switch. After 5 minutes, turn on the AC output switch and then the DC input switch. If the fault persists, replace the board. If the upgrade fails several times, contact your dealer or Huawei technical support. Most common Huawei inverter error codes.
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 …
The inverter fails to communicate with the Smart Backup Box. An unrecoverable fault occurs on a circuit inside the Smart Backup Box. 1. Send a shutdown command on the app. Turn off the AC output switch, DC input switch, and battery switch. 2. Check whether the power cable and RS485 cable between the Smart Backup Box and the inverter are normal.
If optimizers are configured for all PV modules, the PV system can perform a rapid shutdown to decrease the output voltage to below 120 V within 15s and to below 30 V within 30s. Perform the following steps to trigger a rapid shutdown: …
