Inverter - Hardwired

Ok. Got it. That circuit becomes purely Inverter fed. Makes sense. Many thanks all!

I thought you said the separate circuit would be plugged into the inverter.
Keep the inverter on. No need to go back to the circuit breaker.

Or are you feeding the entire RV with the sw2000?

You don't want Maryanne and Tootsie knowing about each other. Get them on the same line talking to each other and your goose is cooked...

Use a DOUBLE POLE DOUBLE THROW 30-amp 120-volt relay center tap to feed the outlet and feed each of the poles with either shore power or inverter, I like he inverter to power the relay magnetic coil.

But as I envision it and tried to describe, it does go back to the breaker. If it didn't, that circuit would be dead when hooked up to shore power?

Thanks for bearing with me...trying to get it right.

WA8...I gotta digest this. I think it was you that helped me with the existing XS400 setup.

There is a separate converter.

The XS400 has a OEM plug and it is plugged into a receptacle that Winnie put there under the sink: this would be 120 IN. As I read you, I do nothing with it...just unplug the XS400 and leave the receptacle there.

120 OUT goes back to the House breaker panel to a breaker that feeds the circuit in question. Currently it is hardwired into the XS40...I think you and SMKETTNER say to just put a plug on it and plug it into the SW2000 and there shouldn't be any excitement if the SW2000 is on or off? And I'll have 120V on that circuit either way?

The manual says the SW2000 is TSW.

Thanks!

On edit: I guess my concern is that if I left the inverter on AND was on shore power, the 2 sources of 120V would make things exciting at the breaker panel?

No, it would not work, if I am reading your post properly.

To use the Pro-watt first you will need a converter, the current pass-through inverter is quite likely your CONVERTER as well.. Now that said, if it was installed "After market" there may already be a converter elsewhere in the RV (Is in mine).

Now, the Existing Xantrex has 120 volt in and out.. Two ways to wire the Prowatt.
1: Disconnect and seal (tape and wire nut tape over the nut) the 120 volt IN wires.. That way you can use them if you ever need 'em, Or (if they are not already done this way) wire 'em to a properly sized outlet (Likely 30 amp) This can be very handy if you have a on-board generator (more on that later).

Then wire the 120 volt OUT to the existing leads (likely just put a plug on the wires and plug into the Pro-watt.. See notes as well.

Option 2.. Wire the output of the Pro-watt and the old 120 volt IN line to the mains and generator in on a small (Same capacity as the breaker feeding the existing inverter/converter) automatic (or manual) transfer switch.. And hook the 120 volt out to the LOAD side of that switch.

NOTE: If the ProWatt is a MSW and your existing is a TSW some things may act weird or otherwise not work properly.. A few items have gotten hot enough to catch fire. (Night lights LED type, believe it or not, and some electric blanket controllers).

I really like TSW inverters.

So if I plug that circuit into the inverter it won't cause a problem if I forgot and left the inverter on and was on shore power?

No heavy load...mainly just TV and laptops.

You could easily feed that single circuit with the SW2000 full time, no transfer switch, plugged in or not.
Extended use of a space heater would be an issue but even a high load item will be fine temporarily.
12v connection needs to be beefed up a bit.
