How to fix no AC output on Outback Battery Charger?
- RRenee OrrAug 11, 2025
If your Outback Battery Charger shows no AC output, start by using a DC voltmeter to check the voltage directly on the DC terminals. If there's no voltage, the problem is external to the unit. If voltage is present, the inverter itself might be damaged, and you should contact OutBack Technical Support. Also, ensure the Inverter ON/OFF jumper is correctly installed as described in the Installation Manual; replace it if it's missing, or install an external switch following the manual's instructions. For initial installations without a MATE3, remove the jumper briefly and reinstall it to reset the unit. If using a MATE3 display, make sure the inverter is set to 'On' and not in 'Search' mode, ensuring the ON/OFF jumper is installed.
