Description
Communication disconnection detection time.
Communication Specifies the fail-safe detection time for the disconnection between
disconnection the SUN2000 and the Smart Dongle.

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 grid-tied
feed-in power 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 Dongle
protection time 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.

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 meter
fail-safe 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.
Communication In the inverter export limitation scenario, if this parameter is set to
disconnection Enable, the inverter will derate according to the active power
fail-safe derating percentage when the communication between the inverter
and the Smart Dongle is disconnected for a period longer than
Communication disconnection detection time.
Communication Specifies the time for determining the communication
disconnection disconnection between the inverter and the Smart Dongle. This
parameter is displayed when Communication disconnection
detection time
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.
For a single inverter, set Closed-loop controller to Inverter.
For multiple inverters, Closed-loop controller can only be set
