28BH Inverter Install

[ncitro]

acoleman43 I understand what you're suggesting but I'd be surprised if that's what the factory had in mind. For one thing if wired that way (back feeding the panel) then you'd need to lock out the main when using the inverter in case you were plugged in to prevent back feeding the pedestal and campground wiring (in case of a power outage for instance).

TucsonJim Any thoughts on the intended wiring here?

Here is my AC panel from my 2022 28BH.

Can you take a pic of the entire circuit breaker panel and all the breakers? The small pic has me confused.

Even better, a map (as I've encouraged everyone to do many, many times) of the breakers-to-outlets and/or appliances would make it so much easier to understand what's happening. The labels may be a red herring.

Thanks AC, would love to have the Multiplus, but way out of my price range. Have to hit the Loto first. Will continue to mull this one over and revert with more questions as i am sure that i will have them. After getting a new RV in October and spending 5 months tearing it apart and replacing/adding stuff, I am looking forward to actually getting it on the road this weekend and actually going for our first night out. Will continue the project in another week.

Al,

Is the inverter prep wire on the side that the battery disconnect switch is on , opposite side of the battery in the front storage? I think that is where it is supposed to come into the front compartment, should be an orange wire loop.

Brian it looks like his inverter prep wires are on the 115v side, given the breakers he has in his panel. That's what I find so confusing. I would agree the inverter prep wires I'd be thinking of would come from the batteries and be there to feed the input of an inverter.

My meaning is the inverter prep wires are located by the battery disconnect switch in the front storage, not on the battery side of the front storage. I believe from the documents that I have just been readign the GD has placed the wires on that side and not the battery side.

I would also like a full pic of the breaker box, from my readings they are putting a different breaker box in that does not require a sub panel but I have not seen one to know how they are wired. We will be back at the factory next week and will get some answers on what's and how's.

Note the top left side of the picture the breaker marker is 50. It looks like he has a panel similar to mine. It's an A-B-A-B-A-B... setup. That's why the 2 AC breakers are next to each other.

Joseph,

Does your unit have the inverter prep?

At some period in 2021 they started the inverter prep with a special breaker panel, curious what yours looks like.

Brian, no i do not have inverter prep that I am aware of. I recognize the layout of the brakes to be similar vs some of the other 50A panels with the main in the center and all of the breakers to each side of that to be of the same polarity,

Hi All,

i wanted to get back to this really good discussion. Upon consideration I am wondering why I even need to leverage the inverter prep wiring (assuming that I could even figure out what the intent of it was)? So if I did the following would I not negate the need:

Shore power TO
Watchdog EMS TO
ATS TO
AC Main 50 AMP breakers

Then add the inverter to the ATS on the other leg IN.

Other than adding the appropriate fuzes/breakers, what did I miss? The current Inverter prep remains as installed, as a couple of breakers on wires looped in the chassis...

That's correct. I'm planning out an install of Multiplus type 2 with a buddy and we're eliminating the inverter prep since he wants to have all his circuits on the inverter. We'll pull out the factory 10/3 NM and I'll just run a short 10 AWG (maybe 8 because I'm cautious) from the out breaker to the in.

That's essentially what I'm doing. I have an onboard generator as well...so...


Shore power to a main breaker and generator to a main breaker.

Main breakers of shore power and generator to ATS.

ATS to the inverter

Inverter to the main AC panel.

??? I don't get the first sentence Shore power to a main breaker and generator to a main breaker. (Long day--I may be missing something.)

Isn't it...

Shore Power and Generator > ATS > Inverter > Main Panel

In that configuration if both shore power and the generator are not going through the Inverter (bypass mode) the inverter kicks in.

The breakers for shore power and generator are completely separate from the main panel. I wanted to have a breaker between shore power and main panel and generator and main panel for OCD reasons.

[allenrude]

Good clarity and discussion. I thought that i was on the right track and rather than spending any more time trying to de-construct how GD intended their inverter prep to be used (would help if they gave us a hunt), i will just ignore and end up with a couple of spare breakers in the 120V box if i ever want to use them for something else. All I have to do now is to justify starting another project as I have spent many more days working on the RV than actually camping in it. Truth is, I enjoy the projects...???
