6. Operation
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.
7.VgWatt-UL (Not Required)
Description: Inverter will change the active output power based on voltage change.
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.
8. Enable both Volt-Var and Volt-Watt modes
Description: Rule21 requires both Volt-var and Volt-watt modes can be enabled.
To set both modes (Volt-var in high priority)
Step 1: Select and set Volt-watt mode at first.
Step 2: Enter "Working Mode" again and select and set Volt-var mode then.
Step 3: To check the priority, a new mode will appear as "V-Q & V-P" which
indicates (Q) Volt-var is in high priority.

To set both modes (Volt-watt in high priority)
Step 1: Select and set Volt-var mode at first.
Step 2: Enter "Working Mode" again and select and set Volt-watt mode then.
Step 3: To check the priority, a new mode will appear as "V-P & V-Q" which
indicates (P) Volt-watt is in high priority.

To reset dual-mode or exit the dual-mode situation
Step 1: Select "Null" mode at first.
Step 2: Enter "Working Mode" again. Redo above dual-mode setting steps to
reset OR set other modes to exit dual-mode situation.
NOTE:
To check the Volt-watt and Volt-var priority, simply enter the working modes.
V-Q&V-P indicates Volt-Var First V-P&V-Q indicates Volt-Watt First
6.5.8.2 Power Rate Limit
Figure 6.37 Power Rate Limit
Power Rate:016%
RateP_Sts-US:STOP
This function is used for changing power ramp up rate.
When the inverter initializes or string MPPT changes, the ramp up rate is limited.
The default setting is stop
(disable).
The setting range is from 10% to 600%, This will change the power change rate per minute.
If these values are changed the inverter may not conform to UL 1741 SA or IEEE 1547
standard
