Auxiliary Output (Charge Controller)
This menu controls the output and functionality of the Auxiliary (AUX) output. The charge controller’s
AUX terminals provide a 12 Vdc output that can deliver up to 0.2 Adc to control external loads. Typical
loads include signaling a generator to start, sending a fault alarm signal, or running a fan to cool the
inverter. See page 11 for an image of the AUX terminals. See page 27 for a description of AUX modes.

Aux Modes for the Charge Controller
Aux Modes include nine options with automatic criteria. The options appear in the following order
when the wheel is drawn clockwise. The
Vent Fan option appears first if the charge controller is set at
factory default values; otherwise, it will tend to display the last option selected. (The options are
described in greater detail beginning on page 29.)
NOTE: The
Remote option allows the MATE3 to use the AUX output for AGS (see page 41). AGS is
intended for systems with a HUB, inverter, and FLEXmax. If the MATE3 connects only to a FLEXmax,
AGS will only work with DC genset programming. The other AGS functions will not work properly.
