4.Fixed-PF
Description: Inverter will output power with fixed power factor.
Setting Range: -0.8 to +0.8
Default value is PF = 1
5. Reac-power (Not Required)
Description: Inverter will generate reactive power based on changing output power.
Note: This Setting is NOT required by UL1741SA Standards.
This function is for maintenance personnel only, wrong operation
will prevent the inverter from reaching maximum power.
6. P-factor (Not Required)
Description: Inverter will change power factor based on changing output power.
Note: This Setting is NOT required by UL1741SA Standards.
This function is for maintenance personnel only, wrong operation
will prevent the inverter from reaching maximum power.
