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.
7.VgWatt-UL
Description: Inverter will change the active output power based on voltage change.
Note: This is the Volt-Watt Setting for UL1741SA Standards.
