You will have to have two assistants: one to turn the relay on when loads are below 500w as AC2 Out is always off by default and one to turn the relay off at loads OVER 500w:

You can set the time offset to whatever you works. You should have something built it so it's not fluctuating on and off rapidly based on your loads.

Also a third may be needed if you plan to use shore power as well to force the AC2 Out relay when shore is available. I've never tested this though as I rarely am on shore power:

You can try this order:

He might know more than me on this one.

Negative. I typically never stay places with shore power so this is unknow territory for me. I can get my multiplus unpacked and run some tests this weekend.

I could have set it to 2500w but instead I set it to turn the ACOut 2 OFF when the overload pre-alarm LED comes on and that seems to work well. Adding the AC1 trigger to turn it ON when we were plugged in was the ticket.

that’s a much better idea for how you intend to use it! And the AC1 for anyone reading this in the future is AC1 INPUT (the assistant screen doesn’t show that in the summary screenshots).

Glad you got it working!
