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, Limited
feed-in takes precedence (when Active power
control is set to Limited feed-in).
6.7.5 Setting Export Limitation Parameters
Context
When the PV and energy storage plant generates power for self-consumption,
countercurrent may feed into the power grid if the loads cannot consume all the
power. In this case, you can set the export limitation parameters on the WebUI to
prevent countercurrent.
●
Scenario without a circuit breaker: The reverse current feeding into the power
grid can be eliminated by sending a command from the SmartLogger to
adjust the inverter/Smart PCS output power.
