Commissioning - Battery Based
Note: Systems must be commissioned while connected to battery banks. PV or AC input only based
commissioning is not recommended or supported.
120V Single Phase
Step 1: Check the following requirements before commissioning:

• 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 bank to the inverters, and power all inverters on.
Step 3: After the startup countdown, old the enter “ ” 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 all inverters into standby mode (fully depress the power button - inverter screen will remain
on).
Step 6: On your host inverter, program setting 28 to "PAL", and press “ ” to save and exit. Repeat the
process to set each slave inverter to "PAL".
Step 7: Turn off all battery breakers. (Power down system)
Step 8: Using a multimeter, verify that there is no voltage on the inverter’s battery lugs.
Step 9: Turn on all battery breakers, and power on inverters.
Step 10: Switch on all AC in breakers. If fault 82 occurs, the inverters will automatically restart.
Step 11: Switch on all AC out breakers.
Note: Step 6 must be completed within 25 seconds of the end of setting the host inverter. 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.
