Thank You Alex for asking this question and thank you Jasin for the information. I have a 2021 MHC 372RD with the solar/inverter prep. I did not know how that wire was connected to the outlets. I am planning a system that will include a DC to DC charger so I can power my refrigerator on the road. I am considering putting one A/C on the inverter so I could cool the coach underway, but not when boondocking. I will probably scale that back to just have the inverted outlets powered by a 2K (perhaps 3K) Watt inverter. Easier install and can still add on later if I get more serious

Alex, for a good review on an inexpensive inverter a battery option, look at “All about RVs” on YouTube, he has a review of a 200Ah batteries and inverter.

Just offering another perspective. I'm not the "eBay guy" that did it for $300 but it's not too terribly difficult to wire an inverter before the panel and have everything power up. As others have mentioned, you'll want to ensure that you're not powering your fridge or water heater by accident. I though wanted all my outlets, my microwave, and my TV to be accessible via the inverter so just powering the outlet circuit was kind of pointless for us.

To do it cleanly you will need an auto transfer switch (I went with this one https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 ) and a willingness to do your homework. I suspect that those spending absurd amounts of money are massively upgrading their battery banks. Aside from the transfer switch (and a relay to disable the charge controller circuit) the price of putting one before or after would be the same for me.

Thanks sahively. A question, if I have an inverter with auto switching, does that negate the need for a transfer switch? I am considering connecting one “side” of my 50 amp system through the inverter with all the items I want to run via inverter on that side. In the near term I can live with just the inverted circuits since I will not be long term boondocking yet.

With an inverter that has "pass through" we have NEVER installed a transfer switch, and any unit that I have seen/worked on with an inverter or inveter/converter I have yet to see a transfer switch in that circuit.

Auto Transfer switches are common with an onboard gen.

I'm out of my element with pass through inverters but I believe (someone here can correct me) that they're meant to pass through a single 120v circuit. If that's the case, then it won't work as a transfer case that disconnects everything and allows you to power everything. Instead, it will only disconnect that circuit when it's not being fed 120 and instead convert the 12v to 120v for that one circuit on its own.

Even if the inverter could handle the entire 50amp feed before your panel, you still have to consider how you'll shut don't the charge controller circuit so you're not using the inverter to charge the batteries. I went with a standard sine wave inverter, a transfer switch, and a relay (https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 ) to disconnect the charge controller circuit whenever the inverter is functioning.

Hope I didn't confuse the hell out of this for you further. Cheers.

Just put the converter on the “non inverted” leg, problem solved without having to buy anything.

He was asking about powering every circuit with the inverter though in which case there'd be no leg that's not inverted.

One side is what I read.
