• Ensure all wire connections are correct.
• Ensure all breakers of the inputs and outputs are in the off position.
Step 2: Provide power from the battery to the inverters, and power both inverters on.
Step 3: After the startup countdown hold the enter button “ ” button for 3 seconds to access the settings
menu.
Step 4: Use the down arrow to go to program setting 28 (AC output mode).
Step 5: Place both inverters into standby mode (fully depress the power button - inverter screen will remain
on).
Step 6: On the host inverter; press the enter button “ ” to access setting 28, program inverter to 3P1,
and press escape button “ ” to save and exit.
Step 7: On slave 1 inverter; press the enter enter button “ ” to access setting 28, program inverter to 3P2
12, and press escape button “ ” to save and exit.
Step 8: On slave 2 inverter; press the enter button “ ” to access setting 28, program inverter to 3P3 12,
and press the escape button “ ” to save and exit.
Note:
Repeat steps 7 and 8 for all slave inverters, setting them according to the phase they are on. Step 7
and 8
must be completed within 25 seconds of the end of step 5. The system will shut down after the
connected inverters are taken out of phase. This is a safety feature that ensures all AC output is correctly
programmed.
If completion in 25 seconds
is not possible and the system shuts down, begin by restarting the
last inverter which was successfully programed and continue until all inverters have been setup correctly.
Step 9: Turn off all battery breakers. (Power down system)
Step 10: Using a multimeter, verify that there is no voltage on the inverter’s battery lugs.
Step 11: Turn on all battery breakers, and power on inverters.
Step 12: Switch on all AC in breakers. If fault 82 occurs, the inverters will automatically restart.
Step 13: Switch on all AC out breakers.
