Setting Parameters For Shutdown at High Feed-in Power
Setting Parameters For Shutdown at High Feed-in Power
This section applies to V300R001C00 only.
The power grid company requires plants to limit or reduce the output power of a PV system when it is too high. If the output power cannot be limited to the range within the specified time, all inverters must be shut down.
Set parameters for shutdown at high feed-in power and click Submit.

Shutdown at high feed-in power
Parameter
Description
Shutdown at high feed-in power
The default value is Disable.
If this parameter is set to Enable, the inverter shuts down for protection when the grid-connection point power exceeds the threshold and remains in this condition for the specified time threshold.
Upper feed-in power threshold for inverter shutdown
The default value is 0. This parameter specifies the power threshold of the grid-connection point for triggering inverter shutdown.
High feed-in power duration threshold for triggering inverter shutdown
The default value is 20. This parameter specifies the duration threshold of high feed-in power for triggering inverter shutdown.
When High feed-in power duration threshold for triggering inverter shutdown is set to 5, Shutdown at high feed-in power takes precedence.
When High feed-in power duration threshold for triggering inverter shutdown is set to 20, Export Limitation(kW) takes precedence (when Active power control is set to Export Limitation(kW)).
