Huawei SUN2000-40KTL-M3 User Manual

Parameter Description
Communication
disconnection
fail-safe
In the inverter export limitation scenario, if this
parameter is set to Enable, the inverter will derate
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
disconnection
detection time
Species the fail-safe detection time in case of
disconnection between the inverter and the Smart
Dongle.
This parameter is displayed when Communication
disconnection fail-safe is set to Enable.

Shutdown at high feed-in
power
● The default value is Disable.
● If this parameter is set to Enable, the inverter shuts
down for protection when the power at the grid-tied
point exceeds the threshold and remains in this
condition for the specied time threshold.
Upper feed-in power
threshold for inverter
shutdown (kW)
The default value is 0. This parameter species the
power threshold of the grid-tied point for triggering
inverter shutdown.
High feed-in power duration
threshold for triggering
inverter shutdown (s)
The default value is 20. This parameter species the
duration threshold of high feed-in power for triggering
inverter shutdown.
● When High feed-in power duration threshold for
triggering inverter shutdown is set to 5, Shutdown
at high feed-in power takes precedence.
● When High feed-in power duration threshold for
triggering inverter shutdown is set to 20, Grid
connection with limited power takes precedence
(when Active power control is set to Grid
connection with limited power).
Note a: This parameter is supported only for the AS4777 or G99-TYPEA-LV grid code.

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 specied 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.
