Harold,
i would call Xantrex and just tell them you need the XWS configuration tool, tell them you are trying to use a 2 wire generator and need option 13 on the auto-start controller in order for it to work.

the wires are N1 and N2 off of the generator.
yellow and blue, it needs 240VAC.
breaking the 240VAC (only one leg) that will close the start relay on the generator.

Hello Owen, or Harold if you got it working.

I have the same 8Kw generac and although my AGS appears to already have mode 13 I would like to get some clarification on the wiring of the AGS to the generator. In the wiring junction box I see 3 conductor wires for the power, and two plugs. One with three wires and one with two wires. What wires from the AGS need to be connected to these and to which ones ?? Thank you very much.
Chris

Chris,
Although I am not completely done yet I do know that the connector with the 2 yellow wires are N1 and N2 that monitor 220 (N1 on one 110v and N2 on the other 110v line).

I believe that Option 13 is already available on mine also even though I spent the $40 to rent one from Xantrex. Turns out it is only for Windows and I have a Mac.

At this point I plan to not use the relay control box that came with the generator package. I may opt to add a simple relay to by-pass the switch when the generator gets the control to start/stop. There has not been enough technical info on anyone who actually has the generator up and running.

Hi Harold,

Lack of technical info is what I am finding as well. I contacted Generac repeatedly but all they care about is telling me how using it off-grid nullifies their warranty, can't get a pin out diagram or anything from them. Xantrex provided just enough info to know it is possible but not enough to make the connection. Seems to be just that bit of 'here is exactly how I did it' info that we are missing.

It appears that I need to use the AGS to trigger a relay that interupts a 220V signal that I need to feed to N1 and N2 via a transformer of some description. But that doesn't give me enough into to figure out which one of the other 3 pins in the 2nd plug might be a bat+ run signal or what any of them are. Looks like with the info I have I could get it to start and stop but have zero feedback to the AGS?

Thanks
Chris

Thanks
Chris

I have the xantrex inverters and went with kohler generator because they are warranted for off-grid and I found out early Generac was not. Seems like the connection to the inverters is the part no-one explaines or understands. I opted out for the generator control box and let the inverter turn the generator on and off when needed or for the monthly run of 15 minutes. Working for a year now great. My electrition called xantrex to hook up to the diodes inside. I could take a pic if you wanted, I"ll be there next weekend.I am also in the boonies with no phone out there or electric. Good luck, Jim A.
