Parameter Description
Power
adjustment
period
Species the shortest interval for a single export limitation
adjustment.
Active power
output limit for
fail-safe
Species the derating value of the inverter active power by
percentage. If the Smart Dongle does not detect any power
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
n
disconnection
fail-safe
In the inverter export limitation scenario, if this parameter
is set to Enable, the inverter will derate according to the
active power derating percentage when the
communication between the inverter and the Smart
Dongle is disconnected for a period longer than
Communication disconnection detection time.
Communicatio
n
disconnection
detection time
Species the time for determining the communication
disconnection between the inverter and the Smart Dongle.
This parameter is displayed when Communication
disconnection fail-safe is set to Enable.
Shutdo
wn at
high
feed-in
power
1
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 specied time threshold.
Upper feed-in power
threshold for inverter
shutdown (kW)
The default value is 0. This parameter species the power
threshold of the grid-connection point for triggering
inverter shutdown.
High feed-in power
duration threshold for
triggering inverter
shutdown (s)
The default value is 20. This parameter species 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).
Note 1: This parameter is supported only for the AS4777 grid code.
