Parameter Name Description
PV plant capacity Species the total maximum active
power in the SUN2000 cascading
scenario.
Maximum grid feed-in
power
Species the percentage of the
maximum active power of the grid-
tied point to the PV plant capacity.
Power adjustment
period
Species the shortest interval for a
single anti-backfeeding adjustment.
Power control
hysteresis
Species the dead zone for adjusting
the SUN2000 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
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.
Communication
disconnection fail-safe
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.
Communication
disconnection
detection time
Species 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.
