Description
Specifies the derating value of the
SUN2000 active power by percentage.
If the Smart Dongle does not detect
any meter data or the
communication between the Smart
Dongle and the SUN2000 is
disconnected, the Smart Dongle
delivers the derating value of the
SUN2000 active power by percentage.
In the SUN2000 anti-backfeeding
scenario, if this parameter is set to
Enable, the SUN2000 will derate
according to the active power
derating percentage when the
communication between the
SUN2000 and the Smart Dongle is
disconnected for a period longer than
Communication disconnection
detection time.
Specifies the time for determining the
communication disconnection
between the SUN2000 and the
Dongle.
This parameter is displayed when
Communication 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.
