7.3.2 Setting Feed-in at Limited Current
Function
The output current of the PV power system can be limited or reduced to ensure
that the output current is within the specified range.
This function applies only to the commercial and industrial (C&I) scenarios in the
UK where the grid code is G99-TYPEA-LV, G99-TYPEB-LV, G99-TYPEB-HV, G99-
TYPEB-HV-MV480, or G99-TYPEA-HV. The SUN2000 app version must be later
than 6.24.00.563.

Description
Communication
In the inverter export limitation scenario, if this
disconnection
parameter is set to Enable, the inverter will derate
fail-safe
according to the active power 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 fail-safe detection time in case of
disconnection
disconnection between the inverter and the Smart
detection time
Dongle.
This parameter is displayed when Communication
disconnection fail-safe is set to Enable.
● The default value is Disable.
● If this parameter is set to Enable, the inverter shuts
The default value is 0. This parameter specifies the
power threshold of the grid-tied 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.

point exceeds the threshold and remains in this
condition for the specified time threshold.

triggering inverter shutdown is set to 20, Grid
connection with limited power takes precedence
(when Active power control is set to Grid
