Hello, I have a 50 amp coach and a multiplus 3000 2-leg 120v. I am wondering if there is a way to have the charger automatically wake up when I plug in the coach, so I don't have to switch it to charge mode. I don't want to leave it on inverter mode because I don't want it to try and run the AC if the power runs out, and I don't have solar to offset the drain on the batteries when not plugged in. Is there a way to do this with the programmable relays?
