rises to a certain value. (This does not guarantee good battery charging. Also, the AGS has to take it on faith that the
generator has even started.)
You do not have to select one function over another — the AGS can start the generator for any reason. If you don’t know
why the generator started, a MATE menu can tell you.
Starting Functions: Battery SOC
The OutBackFlexNet DC sendsbattery state-of-charge (“SOC”) informationto the MATE’s
AGSmenus.IftheFlexNetDCispresent,AGScanalsobeprogrammedtostartandstopthe
generator based on specified levels of charge. SOC is the most accurate AGS function if you are
concerned about battery care.
Without the MATE
The AGS functions, including SOC, are based in the MATE itself and are programmed in the MATE’s own menu area. If the
MATE cannot be installed or must be removed for some reason, AGS cannot be used.
The OutBack FX inverter has a function of its own called GenAlert. GenAlert will energize the
AUX output upon reaching low battery voltage for a certain amount of time, and will turn off
the output after reaching a high voltage for a certain time (all settable). This can allow the
inverter to automatically start the generator, even if there is no MATE. (However, this may not
allow the full charge cycle.) The MATE must still be used for the initial setup, in the FX section
of the menus.
TheOutBackFlexNetDChasanAUXswitchofitsown.Thisisasetofdrycontacts,insteadofa12-voltoutput.The
FlexNet’s AUX switch can perform automatic start if the 2-wire controls are connected directly to it, and it can do so based
on SOC, from the FlexNet’s own readings. (With no MATE, the other AGS functions are still unavailable. Unlike the MATE,
the FlexNet’s SOC feature cannot be used on the FX Aux output.) The MATE must still be used for the initial setup, in the
DCsectionofthemenus.
AGS and AUX Selection
AGS can only send commands to one AUX at a time. You can connect the 2-wire control to one FX inverter in a multi-unit
system, and then direct the AGS commands there. All the above functions will be active on that unit, although not on any
of the other FX inverters. (This will cancel GenAlert or other AUX function programmed into that inverter.) Similarly, AGS
can be directed to the FlexNet’s AUX switch instead, with all AGS functions being active there (although the FlexNet’s own
function is not cancelled). You cannot send AGS commands to the AUX of any OutBack charge controller.
Stopping
TheAUXremovesitsoutputtostopthegenerator,whetheroperatingbyAGS,GenAlert,FlexNetDC.Atwo-wire-start
generator will stop as soon as the wires are disconnected. Along with automatic shutoff, the generator can also be
stopped manually, if the FX fails to see the proper input, or if another error occurs.
AGS can perform generator cooldown. It will disengage the inverter from the generator for a selectable time before
sending the stop command, to keep the generator from stopping while under load. Similarly, AGS can also perform
generator warmup, while starting. These functions are only present for AGS.
