Страница: 106 / 156

Parameter Description
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.
Active power change gradient
(%/s)
Specifies the change speed of the inverter active power.
Derated by active power % (%) Adjusts the active power output of the inverter by percentage.
This parameter is displayed if Remote power schedule is set
to Enable.
If this parameter is set to 100, the inverter outputs based on
the maximum output power.
Derated by fixed active power
(kW)
Adjusts the active power output of the inverter by fixed value.
This parameter is displayed if Remote power schedule is set
to Enable.
For 1000 V inverters, the maximum value of this parameter for
the SUN2000-25KTL-US is 27.5 kW.
Night-time reactive power
output
In some specific 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.
This parameter is displayed when Isolation settings is set to
Input ungrounded, with TF.
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.
Night-time reactive power
compensation (kVar)
During the reactive power compensation at night, the reactive
power is scheduled by fixed value.
This parameter is displayed when Night-time reactive power
output and Enable reactive power parameters at night are
set to Enable.
Reactive power change gradient
(%/s)
Specifies the change speed of the inverter reactive power.
Reactive power adjustment time
(s)
Specifies the adjustment time for the reactive power to reach
the target value during reactive power adjustment.
Plant active power gradient
(min/100%)
Specifies the rate of active power rise due to sunlight changes.
