2022 351m question about inverter and fuel tanks for genny

[StupendousMan]

So I purchased new a 2022 351m. We have always had hook ups but we are starting to do some off the grid camping. So a couple of questions. First, the trailer came with solar, generator and inverter factory installed.

I already upgraded my batteries to lithium (2 100amp) and my converter to charge them. For the inverter any one know how I turn it on? There is a switch in the storage pass through for it but when I push the momentary switch it doesn’t do anything. Any clues on how to go about turning it on? And what does it run?

Which tank is used by the generator? Thanks!!

I didn't have solar/inverter on my 351M, but typically, the inverter is wired only to a few outlets. On my new RV, the inverter ONLY feeds the fridge, nothing else gets power when you're off shore power and not running the generator.

The front tank (closer to the front of the RV) was my generator tank, IIRC. You can confirm that by crawling under the RV. On the passenger side, you'll see the fuel lines going up to the genny, just feel around and you should be able to figure out what tank it goes into. I'd bet it's the front, but, that'll tell you for sure.

Thank you!!!! So found out (haven’t opened the fuel fill station since I bought it) it tells me which one. You are correct it is the front!!! Thank you!

Yes, the front tank is for the generator.

I have a 2022 351MS-R which has the Magnum CSW2012 in it. The Magnum website has the operation manual available for free download.

To turn on the inverter, in the passthrough bay, you have to push the button and hold it in for 1 second or a bit longer. The green light should come on. If that doesn't do it, open the generator door. The inverter is mounted over top of the generator. The inverter has an on/off button on it. Hold it in for 1 second. If the inverter starts, you should hear a beep. The little display should alternate between DC input voltage and AC output voltage. The inverter has a GFCI outlet on the front of it. Plug a small light or fan into it. If the light/fan does not turn on the GFCI may be blown, try resetting it.


I hope this helps.

BTW: I use my back tank to fill the generator tank. To turn on the pump, you need to hold the on and off buttons for a few seconds. Then use the on button to start the pump. The person that did the RV runthrough, did not know that, I had to learn it the hard way (RTFM).
