PV plant Specifies the total maximum active power in the inverter cascading
capacity scenario.
Maximum grid Specifies the percentage of the maximum active power of the
feed-in power grid-tied point to the PV plant capacity.
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.
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 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.

The default value is 0. This parameter specifies the power threshold
of the grid-connection point for triggering inverter shutdown.
The default value is 20. This parameter specifies the duration
threshold of high feed-in power for triggering inverter shutdown.

Total power indicates export limitation of the total power at the
grid-tied point.
Single-phase power indicates export limitation of the power in
each phase at the grid-tied point.
The default value is Disable.
If this parameter is set to Enable, the inverter shuts down for
protection when the grid-connection point power exceeds the
threshold and remains in this condition for the specified time
threshold.

inverter shutdown is set to 5. Shutdown at high feed-in
