No. Parameter Description Remarks
2 Schedule instruction
valid duration (s)
Species the time for maintaining
the scheduling instruction.
When this parameter is set
to 0, the scheduling
instruction takes eect
permanently.
3 Maximum active
power (kW)
Species the output upper
threshold for the maximum active
power to adapt to dierent market
requirements.
-
4 OFF at 0% power
limit
If this parameter is set to Enable,
the inverter shuts down after
receiving the 0% power limit
command. If this parameter is set
to Disable, the inverter does not
shut down after receiving the 0%
power limit command.
-
5 Active power
change gradient
(%/s)
Species the change speed of the
inverter active power.
-
6 Derated by xed
active power (kW)
Adjusts the active power output of
the inverter by xed value.
-
7 Derated by active
power % (%)
Adjusts the active power output of
the inverter by percentage.
If this parameter is set to
100, the inverter outputs
based on the maximum
output power.
8 Night-time reactive
power output
In some specic application
scenarios, a power grid company
requires that the inverter can
perform reactive power
compensation at night to ensure
that the power factor of the local
power grid meets requirements.
-
9 Enable reactive
power parameters
at night
When this parameter is set to
Enable, the inverter outputs
reactive power based on the
setting of Reactive power
compensation at night.
Otherwise, the inverter executes
the remote scheduling command.
This parameter is displayed
when Night-time reactive
power output is set to
Enable.
10 Night-time reactive
power
compensation
(kVar)
During the reactive power
compensation at night, the
reactive power is scheduled by
xed value.
This parameter is displayed
when Night-time reactive
power output and Enable
reactive power parameters
at night are set to Enable.
