Description
Active power Specifies the derating value of the SUN2000 active power
output limit for by percentage. If the Smart Dongle does not detect any
fail-safe 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.
Communicatio In the inverter export limitation scenario, if this parameter
n is set to Enable, the inverter will derate according to the
disconnection active power derating percentage when the
fail-safe communication between the inverter and the Smart
Dongle is disconnected for a period longer than
Communication disconnection detection time.
Communicatio Specifies the fail-safe detection time for the disconnection
n between the SUN2000 and the Smart Dongle.

Maximum grid Specifies the maximum active power transmitted from the
feed-in power grid-tied point to the power grid.
Power Specifies the shortest interval for a single export limitation
adjustment adjustment.
period
Maximum Specifies the time for detecting power meter data. If the
protection time Dongle does not detect any power meter data within the
preset time, the Dongle delivers the preset value of Active
power output limit for fail-safe for protection.
Power raising Specifies the step for grid-tied power adjustment.
