Clarification installing inverter and removing converter

[chaostactics]

I'm at the final stages of bringing my victron multiplus online.

Just looking for clarification.

Victron AC out goes to my main distro panel where my shore power in was?

The shore power now goes to the Victron AC in?

The DC out from the Victron originating at the Lynx distributor goes to DC panel where the battery was connected? (The converter will be unhooked from the DC panel).

I would recommend that you install a circuit breaker between the output of the transfer switch and the Invertor. In my case it was a 30 amp breaker.

That location would cover both shore power and generator output.

I got this advice from Lou to be in code.

Between shore power and AC in on the Victron?

Yes but your AC input comes from both the shore power or the generator. So put the circuit breaker after the transfer switch if you have one.

I have no built in gen. If I were to run a portable gen I would connect it to the shore power outlet.
I don't think I have a transfer switch, up until now I've only had one AC source (shore power).


As I understand it the multiplus will handle the switch over between DC and AC on it's own.


*However, people have mentioned having some sort of shunt to bypass the Victron Multiplus in case of it having a fault or needing to be pulled out of circuit to service.

I'm not sure what that device is though...

On some RVs you do not have a transfer switch and the power cord is simply switched to the generator.

What I was referring to was a circuit breaker to be placed between incoming AC from either source and the Invertor.

I'm lost on this though. If there wasn't a circuit breaker there before i.e. between shore power and my main panel (there is a 30A main breaker on the panel) why would I add a breaker now?

All I'm doing is linking shore power to the multiplus instead of linking it directly to my main panel.

Shore power pedestal, house grade outlet, or generator should all have 30A breakers on them.

Even if I added another somewhere in the system, I'm not even sure where I'd mount another breaker in a place that would be accessible.


PS I'm 100% not being argumentative if it comes across that way. I'm genuinely confused/lost.

 

[HueyPilotVN]

When I was feeding my main panel directly from the Invertor, as I have been since, I was advised that to stay code compliant that I should place a circuit breaker between the transfer case output and the input for the Invertor.

Maybe Lou Schneider will post the codes that he referenced and the reason for having the breaker. Possibly it is to protect the Invertor.

I am sure that Lou will advise us.

I am not taking this as argumentitive and I trust that Lou had some reason to tell me to insert the breaker.

If it helps this is what I used to insert in the line from the transfer switch.

I simply found the Romex that went to the main panel under the bed and cut it and inserted the breaker and redirected it to the Invertor.

I mounted the box with the breaker in the short wall at the foot of the bed,

It is an easy install. it is simply inserted between both ends of the hot wire.

I also inserted another circuit breaker just like it in the output from the Invertor to the main panel. The main panel also has a main circuit breaker but I am a kind of belt and suspenders guy.

Is the breaker on the pedestal, house outlet, or generator not a breaker that protects the wires to the victron?

Why did you put a double breaker in-between the shore power and victron. If you're only interrupting the hot wire?

It was cheap and filled the opening in the box cover better than a single one.

I'm still struggling to guess where I could even fit one* and I still don't understand why I'd need one if all sources connected to the shore power inlet already have breakers.

* It's not that expensive considering the absurd amount of money I've already spent on this system but the only place I can think of mounting it is behind the distro panel which is crazy.

The pedestal CB would suffice to protect the Multiplus when on shore power. When on a generator, where is the CB? If you have a generator with a built in CB then yes. As long as the cabling can handle the 50A for the AC input, then you can connect to either 30A or 50A pedestal.

It sounds like your shore power runs all the way from the back of your trailer to the front of your trailer. Is there no place along that distance where you have access to the wires and can mount a simple electrical box that can be recessed in a wall or panel along the route? Mine are recessed in the panel at the foot of the bed.

I am not trying to be rude but given your reluctance to simply add a breaker, I find it interesting that your screen name is Chaos Tactics. This is not Rocket Science.

The only places I have access to wires is directly behind the main panel and inside the front bay. If I put a breaker in the front bay I would have to put another cut/splice in the AC supply line.
