Parameter
Description
Frequency change rate
protection
Set this parameter to Enable to protect the inverter when the grid frequency
changes too fast.
Frequency change rate
protection threshold (Hz/s)
Specifies the frequency change rate protection threshold.
Frequency change rate
protection duration (s)
The inverter is protected when the grid frequency change duration exceeds
the value.
Soft start time after grid failure
(s)
Specifies the time for the power to gradually increase when the inverter
restarts after the power grid recovers.
Power Adjustment Parameters
Parameter
Description
Remote power schedule
If this parameter is set to Enable, the inverter responds to the scheduling
instruction from the remote port. If this parameter is set to Disable, the
inverter does not respond to the scheduling instruction from the remote port.
Schedule instruction valid
duration (s)
Specifies the time for maintaining the scheduling instruction.
When this parameter is set to 0, the scheduling instruction takes effect
permanently.
Maximum apparent power
(kVA)
Specifies the output upper threshold for the maximum apparent power to
adapt to the capacity requirements of standard and customized inverters.
Maximum active power (kW)
Specifies the output upper threshold for the maximum active power to adapt
to different market requirements.
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 fixed active power
(kW)
Adjusts the active power output of the inverter by fixed value.
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.
Reactive power change gradient
(%/s)
Specifies the change speed of the inverter reactive power.
Plant active power gradient
(min/100%)
Specifies the rate of active power rise due to sunlight changes.
Average active power filtering
time (ms)
Specifies the period of active power rise due to sunlight changes. This
parameter is used with Plant active power gradient.
