ReactivePowerDerating
5.2.2.2.3
The “ReactivePowerDerating” submenu is used to set the Grid reactive power derating parameters including PF
parameters and Q parameters, etc. The parameters are shown in Figure 5-10.
Note: The PF and Q value can be adjusted by remote software if the “Remote” is selected.
