Please follow this instruction instead of the user manual to set the inverter working mode if needed. Different grid standards correspond to different working mode settings.
UL1741SA Standard include “UL-240V”, “UL-208V”,” UL-240V-A”, “UL-208V-A”
Rule21 Standard include “R21P3-240”,” R21P3-208”,” R21P3-24A”,” R21P3-20A”
ISO-NE Standard include “ISONE240”, “ISONE208”, “ISONE240A”, “ISONE208A”
Working Mode Setting path:
Advanced Settings -> Password:0010 ->STD.Mode Settings ->Working Mode Set
Grid Standard Setting Path:
Advanced Settings -> Password:0010 -> Select Standard.
Mode 1: NULL (Applicable for all ISO-NE, UL1741SA standard and Rule21 standard)
Description: Inverter is not under any working mode.
Mode 2: Volt-var (Applicable for both UL1741SA standard and Rule21 standard)
Description: Inverter will change the reactive power based on voltage change.
Mode 4: VgWatt-UL (Applicable for UL1741SA standard)
Description: Inverter will change the active power based on voltage change
Mode 5: Volt-Watt (Applicable for Rule21 standard)
Description: Inverter will change the active power based on voltage change
Rule 21 standards require both Volt-var and Volt-watt modes are enabled
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" whichindicates (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" whichindicates (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.
