Power inverter installation

I would look at a 600w inverter if max load is 500w. No sense installing big fat wire, fuse etc required by a 2000w.

Transfer switch has two inputs, one output. Inverter to one input, utility power to the other input. Output goes to the trailer etc. It will come with instructions.

You will need a 30a rated switch if the cord has a 30a RV connector.

Why would he want to transfer every load? As in the 30 amp cord.
You just need to transfer the circuit or circuits you want the inverter to run.
You sure don't want to power your converter/charger from the inverter.
I run the freig and tv circuits. That way I don't have to run freig on propane when traveling.

JD - Don't know how much you are planing to load down the 2000W INVERTER but if you look at the specs on your two planned deep cycle batteries you may find they will only produce enough power to run your 2000WATT Inverter for just a few minutes if loaded down for the total 2000WATTS.

A standard 105AH deep cycle battery will only produce 12VDC@75AMPS for only 15 minutes or so before it gets down to its 50% charge state when you need to re-charge before doing damage to the battery.. Might get 30 minutes using two in parallel..

Large INVERTERS are very 12VDC power Hungry. You probably will have a 200AMP or more fuse between your battery system and the 2000WATT Inverter. That is alot of DC current... It may also require a heavy duty truck alternator setup to re-charge them like you indicated you wanted to do. A standard truck alternator may go up in blue smoke...

Just more things to think about...

Yea I am aware of all that, when the inverter is running off DC power it will be running a max of 500w, and anything after that will be plug into shore power. So my question is if I buy an inverter with an automatic transfer switch how do I wire the input and output of the 120v side

That inverter does not have a build in transfer switch. I had that same unit in my previous 5er. Worked well until it craped out. It's not a sine wave but a modified sine wave if that matters to you.
There are less expensive full sine wave units on the market.
You can either use a transfer switch as simple as a double pole double through switch or just a simple plug set up as mentioned before.
Leviton Double Pole Double Throw switch aka DPDT

This is what I'm currently using in the MH. Quite and works well.

This is the power inverter I am going to install. If I read it right it looks like it has a built in automatic transfer switch.

So your shore power is wired directly into the inverter then to your breaker box

Hi,

You can do a manual system with plugs (I do) or use a transfer switch.

I simply have a 30 amp outlet on my inverter--and I plug in the OEM shore power cord to it. It requires the converter to be turned off when using the inverter.
