Inverter wiring

This is due to how AC power works, too much to explain here but do some youtube searches on AC power and grounds/commons and hot wires. Pretty interesting if you like to learn about this sort of thing.

The only way around this, if using an inverter with transfer switch, is for that inverter to also have a charger and the converter just be unwired. Or to wire the converter before the inverter, meaning creating a Y from the shore plug one end going to the inverter input and the other to a new breaker (totally separate from the power center buss bar) and then wire the converter into this breaker. This separates the two 120v areas.

Ok, now even more confused.....I have talked to some people and was told I could wire my 2000w inverter (no transfer switch) right to the batteries, with a fuse on positive between inverter and batts, then turn off RV converter, then plug my (shore) power cord into the 2000w inverter (with pigtail - 50A to 15/20A) and I'm good to go.

Just to be clear, you cannot go directly into an inverter with shore power (on AC input side) without a built in transfer switch. At least not without causing a fire or frying something bad.

You can take the inverter, and I think this is what you are saying, hook up to batteries (with fuse) and then AC output as a cable/plug that can plug into your shore power on the outside of the trailer. This will work fine, and yes turn off the converter.

This is more complex than what you were mentioning but shows where and how a transfer switch is used. (sometimes this can be built into the inverter to simplify wiring)

This is one of the easiest to understand diagrams I have found.

This is all I am looking to do! 🙂

Yes, very good diagram!

What happens if I take out the positive side of the line from the converter/charger to the battery when I have the shore power plugged into the inverter (wired from the same battery)? So power will still go to the converter/charger, but the positive wire from converter charger to the battery is interrupted.
