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.
1.NULL (Mode Reset)
Description: Inverter is not under any working mode.
2. Volt-Watt
Description: Inverter will change the active output power based on voltage change.
Note: This is the Volt-Watt Setting for Rule21 Standards.
