Schneider Conext 6848 with AGS to Generac 0064622

I am trying to figure out how to connect the AGS to the Generac. 

Any help would be appreciated, or sources?

Off grid 48v system, 2 sets 15x255 watt panels, 2xFlexmax80 Charge Controllers, 2 sets Trojan 6v x 8 batteries, 16KW Generac with transfer switch (Grid long gone).

    I'm pretty sure the reason no one has answered this is because you didnt list the type of inverter  that goes with the automatic generator starter or the model of the generac

    before anyone can answer, you will need to provide those things

    He's running a Conext 6848.

    I don't use auto start but looking at the 6848 manual you need Conext part # 865-1060-01 (page 1-9) which is their generator auto start box $200 ( ) and a breaker in the PDP to run the power through

    You may be able to directly trigger the generator through the AUX connections (Page 3-5 through 3- 7) by programming it to provide a few watts at 12v  when low battery voltage is detected.

    Also needs a device (combox or SCP) to program the settings for the AGS I think .

    I am using a Xantrex AGS and a relay.  I provide power 120v from the inverter to the Generac N1-N2 leads, through the relay.  When AGS desides to run the generator (like low battery or whatever), it opens the relay so Generac thinks the power is out.  BUT, it seems like as soon as the grid goes down, the generator starts, ignoring the inverter power on N1-N2.  I am not sure why this doesn't work, but it might be in the programming of the Generac.  Any thoughts?

    I used this and the gen works fine

    Which wires did you use from the Xantrex AGS and what generator type did you set in the AGS?
