I was just informed by Signature Solar that the RSD relay port 2 cannot produce 12vdc to keep the battery at the starting battery for the generator charged. If you all find out something different, please let me know.

@eg4c Could you please let me know exactly how you have the generator wired to your grid boss? Is it possible to get some pictures? I was told that I still needed the ATS for the generac. Any help would be appreciated.

- Generator wires (thick ones) go into "generator"
- IMPORTANT IF YOU WANT TO FOREGO ATC: Generator must be reconfigured for "2-wire start"
- inside generac panel: "VAC Load Supply" wire connects to one of the electric phases in the panel. two yellow wires no longer used. All wires from "DC Common", "+12V", "TRANSFER" are no longer used.
- connect two wires to your generator "2 wire start" PINs, as described here: https://diysolarforum.com/threads/replacing-generac-ats-with-grid-boss.94155/post-1290777 . These could be different on different models. If generator is reprogrammed for 2-wire start, shorting them should start generator, and un-shorting them should stop it
