Huawei SUN2000 M5 Series User Manual

Parameter Name Description
Communication
disconnection fail-safe
In the SUN2000 anti-backfeeding
scenario, if this parameter is set to
Enable, the SUN2000 will derate
according to the active power
derating percentage when the
communication between the
SUN2000 and the Smart Dongle is
disconnected for a period longer than
Communication disconnection
detection time.
Communication
disconnection
detection time
Species the time for determining the
communication disconnection
between the SUN2000 and the
Dongle.
This parameter is displayed when
Communication disconnection fail-
safe is set to Enable.
Grid connection
with limited power
(%)
Closed-loop controller ● If multiple SUN2000s are
cascaded, set this parameter to
SDongle/SmartLogger.
● If there is only one SUN2000, set
this parameter to Inverter.
Limitation mode Total power indicates export
limitation of the total power at the
grid-tied point.
PV plant capacity Species the total maximum active
power in the SUN2000 cascading
scenario.
Maximum grid feed-in
power
Species the percentage of the
maximum active power of the grid-
tied point to the PV plant capacity.
Power adjustment
period
Species the shortest interval for a
single anti-backfeeding adjustment.
Power control
hysteresis
Species the dead zone for adjusting
the SUN2000 output power. If the
power uctuation is within the power
control hysteresis, the power is not
adjusted.
