  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.

Why does my Outback Power Systems Battery Charger read AC input when no source is present?

  michelle52Sep 12, 2025
  If your Outback Power Systems Battery Charger reads AC input even when no source is present, the internal transfer relay may be damaged. Disconnect the AC input wires and turn the inverter on. Test the AC HOT IN and NEUTRAL IN connections with an AC voltmeter. If voltage appears there, the transfer relay may be jammed.

How to troubleshoot no LEDs on Outback Power Systems Battery Charger?
- M
  mitchellsherrySep 14, 2025
  If there are no LEDs lit on your Outback Power Systems Battery Charger, it indicates there is no DC voltage. Use a DC voltmeter to check the voltage directly on the DC terminals. If there is no voltage, the problem is external.

Why does my Outback Power Systems Battery Charger have no AC output?
- J
  Jamie KingNov 19, 2025
  If your Outback Power Systems Battery Charger has no AC output and will not invert, here are a few potential causes: * The jumper JP1 might be missing. Check the Installation Manual for its location and confirm it is present. If it's missing, replace it, or follow the manual's instructions to install an external switch. * The unit may have defaulted off, especially during initial install without a MATE present. If JP1 is confirmed present, remove it with narrow pliers and then reinstall it. * The inverter may be set to OFF. If you have a MATE system display, set it to ON using the INV hot key. * The inverter might be set to SRCH (Search mode). If constant power is needed, use the MATE system display to set it to ON with the INV hot key. If Search mode was intentional, no action is...

What to do if my Outback Power Systems GFX1312E Battery Charger will not connect to AC source?
- M
  Michael CruzNov 22, 2025
  If your Outback Power Systems Battery Charger will not connect to the AC source, there could be several reasons: * There might be no AC input. Check the AC voltage on the inverter’s input terminals. If there's no voltage, the problem is external. If voltage is present, the inverter might be damaged. * The inverter could be set to disconnect from AC. Using the MATE system display, change the AC Input Control setting from DROP to USE with the AC IN hot key. If this setting was intentional, no action is required. * HBX mode might have disconnected from AC. Check the AC IN hot key screen on the MATE system display to see if HBX mode is in use. If activated prematurely, check the HBX settings. If this was intentional, no action is needed. * The grid use function may have disconnected f...

Why is the charge rate low on my Outback Power Systems GFX1312E Battery Charger?
- T
  Thomas CookNov 24, 2025
  If your Outback Power Systems Battery Charger has a low charge rate, consider the following possibilities: 1. The charge might be complete or nearly complete. Check the DC voltage and charging stage using the system display or a DC voltmeter. 2. The system display's DC meter might read significantly higher than the actual battery voltage. Check the DC voltage on the inverter's DC terminals. If different from the system display, the inverter could be damaged. Also, check the DC voltage on the batteries with a voltmeter; a difference from the inverter reading could indicate a DC connection problem. 3. The generator type may not work well with the Grid/Generator Support feature. Turn off the ac2/gen support feature in the ADV/FX/GEN menu using the MATE system display. Note that the AC tra...

Why do loads drop out during transfer on my Outback Power Systems GFX1312E?
- U
  uwilsonNov 27, 2025
  If loads drop out or crash during transfer with your Outback Power Systems Battery Charger, it could be due to several reasons: * Erratic AC source voltage. Check the AC voltage on the inverter's input terminals. If it's inconsistent, the problem is external. The AC source voltage may have dipped or hovered too low to crash a sensitive load before the inverter took over. Raise the lower limit setting if the ac1/grid or ac2/gen lower limit was turned down to accommodate a problematic AC source. If this setting was intentional, no action is required. * The inverter was set to SRCH (Search mode). The unit will take a moment to come out of Search mode after transferring. If constant power is required, set to ON with the INV hot key using the MATE system display. If this setting was intent...
