Bought it used, dealer removed old inverter and left it cables capped. I asked what was wrong and they said the inverter died. I’m afraid of being something else also. So I bought a regony 2000w inverter on sale for 150. I have done one for a company trailer but im not sure how they did things on this one.

How does a transfer works from shore power and the inverter when shore power is connected

There is a plug with a purple and green wire that was connected together. At first I thought I just need to connect the red and black battery cables to the inverter and use a male to male cord and plug from the inverter into the white plug that way it would send power to the outlets in the trailer

But now there is a white wire, is that a neutral?

Tracing the purple cable to the electrical panel its on its on breaker but I can’t find the green

Battery cable will be upgraded to a 2/0awg right now it’s a #2awg

White cable looks like a 8awg

What’s the right way to do this

Thanks

Hello, so I recently got a trailer with electric breakers and a 7pin connector. Now I used to have a 4 pin already installed on the van. So I purchased a 7way adapter which came with I’ll say the most a 12awg wire. I ran the break controller installation at the front of the van and ran 2 8awg wires one for the break and another for 12v. Unfortunately there is not very much room at the front of the Promaster to add a smart battery isolator, so I was thinking of adding one to the back of the van near by the 7pin connector. I wanted to use the isolator to make sure the trailer won’t withdraw power when the van is not running. I have a 280ah livepo4 battery and the trailer have one solar panel that recharges it slowly. I don’t plan to run much from the van but I’m not sure how this works and how much power the trailer will withdraw from the van and if the cables will be enough. I’ll have a 30amp fuse at the 12v line coming from the battery.

Please guide me on what I could be doing wrong
Thank you
