5. Reac-power (Not Required)
Description: Inverter will generate reactive power based on changing output power.
Note: This Setting is NOT required by Rule21 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 Rule21 Standards.
This function is for maintenance personnel only, wrong operation
will prevent the inverter from reaching maximum power.
