Description
Power Specifies the shortest interval for a single export limitation
adjustment adjustment.
period
Active power Specifies the derating value of the inverter active power by
output limit for percentage. If the Smart Dongle does not detect any power
fail-safe meter data or the communication between the Smart
Dongle and the inverter is disconnected, the Smart Dongle
delivers the derating value of the inverter active power by
percentage.
Communicatio In the inverter export limitation scenario, if this parameter
n is set to Enable, the inverter will derate according to the
disconnection active power derating percentage when the
fail-safe communication between the inverter and the Smart
Dongle is disconnected for a period longer than
Communication disconnection detection time.
Communicatio Specifies the time for determining the communication
n disconnection between the inverter and the Smart Dongle.
disconnection This parameter is displayed when Communication
detection time disconnection fail-safe is set to Enable.
● 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.
The default value is 0. This parameter specifies the power
threshold of the grid-connection point 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, Grid
connection with limited power takes precedence
(when Active power control is set to Grid connection
with limited power).
