OK, some confusion on inverter/shore power wiring

[thefakehutch]

So I have a Victron Inverter (just an invertor, not multi). How do I wire this in reference to shore power? Do I need an ATS? I am getting the remote to turn it off remotely.

What model number? If it doesn't have an internal transfer switch, you should get an ATS.

Victron Energy Inverter, Phoenix 12V 1200VA 120V

I don't think it does.

That inverter series doesn't come with a built in transfer switch.

So you need to wire it to your 12v battery’s. As close as possible with a good size wire.
