Inverter Problems With My 2014 Sightseer 30A

[Jleer]

So i have an inveter problem.
We are currently on a trip and 3 day stay at a harvest host. No services. Before arriving here we were prepping for this trip and discovered our shore power connection for 110 power source through connectors to 50 amp cable was generating pes3 errors on our ems progressive industries surge ptotector.
I called winnebego support who suggested i might have aburned out 150 fuse for the inverter. How did that that happen? They suggedted checking voltage at fuse and at inverter. Waiting to check when is is little bit more hospitable (currently rain and 40s). Have you experienced this sort of thing? If fuse where to buy it on the road?

We really don't have enough of the details to make a good guess at the moment as there seems to be several questions without answers.
One is that we don't know what RV you have . AGE, Model, Floorplan? They are all different, so we don't have much to go on and no way to look up the info!

Then there is the question of the inverter and the error code you were getting. An inverter uses DC battery power to "make" AC power. So if the cord is plugged into AC power, why is the inverter turned on or involved at all?
Or does your RV have an item called an inverter charger which the name has been dropped to inverter?

I think of the surge protector as acting to monitor the power coming in on the cord.
I'm not seeing the inverter being involved at all?
We normally think of the inverter as helping us get AC when we don't have it plugged in nor running the generator?
More details needed there to help clear some confusion.

Sorry, not able to see the picture well enough to help much!

Jleer-

I agree with Morich: This sounds like a problem with shore power or the EMS. When it's working correctly the EMS will not pass incoming AC power to the next device, which is usually a transfer switch.

What is the model of the Progressive Industries EMS? It should say on the outside of the box.

What is the exact error displayed? Is it PE3?

Does the display show voltage (e.g., 120V or 240V), frequency (e.g., 60H for "60 hertz") and its current state, such as "E0?" The display shows these in rotation, about 3 to 5 seconds for each code.

Is any AC passing through the EMS at all? That means, is there any 120V AC service in the coach at all?

Did this start when you connected to the post at Harvest Host, or also at home? (You state it started at home, just checking, though.)

Wiring diagrams for your coach are available here. A typical AC diagram for the 2014 Sightseer 30A is here (see page 6 of that file, which is sheet 5 of the diagram set).

I knew I was missing something vital when I got to the point where Winnebago suggested a 150 (amp?) fuse to power a 1000 WATT inverter, if we are using the right names and the right RV!

He said "no services" at the HH site. The error code was before leaving home.
If he would share his details we might be able to help. Without brand/model of inverter there is no way to look up the operators manual.
I guess he has already found the answer, since he hasn't responded to your request.

Just an FYI... Winnebago just assembles all these 3rd part parts and isn't the one to ask for help in matters like this. Step one is to look at your inverter and get the name and model info. Then contact the inverter company not Winnebago.

Likewise, as the others have said, we need that same info about who made the inverter and what is it's model info.

Could Winnebago be correct about a 150amp fuse? I suppose they could but if that's the problem go buy lottery tickets before your luck runs out.

Start over. as I've suggested above and go from there.

Best of luck!

Lots of things to question as a 150 amp fuse is going to be pretty big if we are speaking of the 110AC on a 50 amp coach! A 150 amp might be more likely in the 12VDC side??

Is Winnebago talking about a mega fuse for the inverter? Our inverter (Victron Multiplus II) was accidentally installed with a 125 mega fuse on the bus bar and the fuse blew. Replaced it with a 400 and we had power again.
