Parameter Name Description
Maximum grid
feed-in power
Species the maximum active
power transmitted from the
grid-tied point to the power
grid.
Power adjustment
period
Species the shortest interval
for a single anti-backfeeding
adjustment.
Power control
hysteresis
Species the dead zone for
adjusting the inverter output
power. If the power
uctuation is within the power
control hysteresis, the power is
not adjusted.
Active power
output limit for
fail-safe
Species the derating value of
the inverter active power by
percentage. If the Smart
Dongle does not detect any
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.
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.
