Description
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.
disconnection
This parameter is displayed when Communication
detection time
disconnection fail-safe is enabled.
Closed-loop ● If multiple SUN2000s are cascaded, set this parameter

● If there is only one SUN2000, set this parameter to
Limitation Total power indicates export limitation of the total power
mode at the grid-tied point. (When a single-phase meter is
connected, only Total power can be selected.)
Single-phase power indicates export limitation of the
power in each phase at the grid-tied point.
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.
threshold
Power Specifies the shortest interval for a single export limitation
adjustment adjustment.
period
Active power Specifies the derating value of the inverter active power by
output limit for percentage. If the Smart Dongle does not detect any power
fail-safe 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.
