Description
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 time for detecting
meter data. If the Dongle does not
detect any meter data within the
preset time, the Dongle delivers
the preset value of the Active
power output limit for fail-safe
to the inverter for protection.
Specifies the threshold for raising
the inverter output power.
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 Dongle is
disconnected for a period longer
than Communication
disconnection detection time.
Specifies the time for determining
the communication disconnection
between the solar inverter and the
Dongle.
Specifies the derating value of the
inverter active power by
percentage. If the Dongle does not
detect any meter data or the
communication between the
Dongle and the inverter is
disconnected, the Dongle delivers
the derating value of the inverter
active power by percentage.
