Description
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.
● If multiple SUN2000s are
cascaded, set this parameter to
SDongle/SmartLogger.
● If there is only one SUN2000, set
this parameter to Inverter.
Total power indicates export
limitation of the total power at the
grid-tied point.
Specifies the total maximum active
power in the SUN2000 cascading
scenario.
Specifies the percentage of the
maximum active power of the grid-
tied point to the PV plant capacity.
Specifies the shortest interval for a
single anti-backfeeding adjustment.
Specifies the dead zone for adjusting
the SUN2000 output power. If the
power fluctuation is within the power
control hysteresis, the power is not
adjusted.
