What to do if my Outback Power Systems GFX1312E Battery Charger will not charge?

  William LeeAug 17, 2025
  If your Outback Power Systems Battery Charger will not charge, it could be due to a couple of reasons. First, check if there is AC input. If the AC input is fine, then the charger might be set to OFF. Using the MATE system display, check the Charger Control screen with the AC IN hot key and set it to ON or AUTO. If the charger was intentionally set to off, then no action is required.

Why does my Outback Power Systems Battery Charger click repeatedly?
- R
  Robert MartinezSep 2, 2025
  If your Outback Power Systems Battery Charger clicks repeatedly and the AC output voltage fluctuates, here are potential causes: * The inverter's output might be connected to its input. Disconnect wires from either the inverter's AC input or output terminals, or both. If the problem disappears, it's an external wiring issue. The inverter's AC HOT IN and AC HOT OUT must remain isolated from each other. * Low AC input voltage. Test the AC HOT IN and NEUTRAL IN connections with an AC voltmeter. If the voltage is low or fluctuating, this is an external problem. * The inverter may be set to sell to the utility grid but is connected to a generator. Set the AC transfer control menu to 'gen' using the MATE system display to prevent it from selling.

Why won't some inverters invert in my Outback Power Systems multi-inverter system?
- M
  Michael ByrdSep 5, 2025
  If one or more inverters in your multi-inverter Outback Power Systems Battery Charger system won't invert while others do, it could be because the unit is a slave and is in Power Save mode. Check the Power Save levels in the ADV/FX/STACK menu using the MATE system display and test with loads to see if the inverter comes on at the appropriate levels. If this setting was intentional, then no action is required.

What if generator fails to start when triggered by AUX output of Outback Power Systems GFX1312E Battery Charger?
- B
  Benjamin BradleySep 8, 2025
  If a generator or external fan fails to start when triggered by the AUX output on your Outback Power Systems Battery Charger, it could be because the AUX output is either not connected or is not delivering 12-volt output. First, test the generator or device to confirm it functions. Then, test the AUX+ and AUX– terminals with a DC voltmeter. If voltage is present with the AUX LED on, there is an external connection problem. If voltage is not present with the AUX LED on, the AUX circuit may be damaged.
