Parameter Name Description
Communication
disconnection fail-
safe
In the inverter anti-
backfeeding 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.
Communication
disconnection
detection time
Species the time for
determining the
communication disconnection
between the inverter and the
Dongle.
This parameter is displayed
when Communication
disconnection fail-safe is set
to Enable.

a
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
specied time threshold.
Upper feed-in power threshold for
inverter shutdown (kW)
● The default value is 0. This
parameter species the
power threshold of the
grid-connection point for
triggering inverter
shutdown.
