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.
Default Settings for UL1741SA:
Rated 480V Grid
V1:less than V2
V2:less than Vstart

7. VgWatt-UL
6.7.9.1.2 With Rule21 Standard selected
NOTE
The other three working mode"P1-V-Watt","P1-V-Var" and
"P1-V-P&V-Q" are NOT applicable for settings.
Based on Rule21, working mode 1,2,3,4 can be used by grid operator.
NOTE
The following modes are for "R21P3-480", "R21P3-48A".
