So What Is My Inverter For?

Hi All!

I just upgraded from a travel trailer to a motorhome, and with it I got a new toy! An invertor! But I also have a generator. It seems to me that I would probably only use the invertor when driving the rig? Is that right? If I have shore power, or can run the generator, when else might I use an invertor? I would think you would want to limit it's use if the rig isn't running...

Am I thinking straight on this?

your inverter converts dc power to ac power so you can run the things that only work off of A/C power. My Georgetown has a residential fridge and that is the only thing that is plugged into the inverter. Some folks use them to plug TV's or other small devices that will only run on A/C power. You want to limit the amount of time you are running off coach battery withour plugging in to avoid draining the coach batteries.

does your rig have a residential fridge?

I do not believe you have a invertor in your 2011 378TS model unless a previous owner installed it.
Now if you are talking about the box in your drivers side rear that is a Convertor/ battery charger that charges your coach batteries.
Here is what mine looks like in my 2012 378TS. I do not have a residential 120 volt refrigerator.

Thanks Gohawks and Iggy!

My refer is a dometic (not residential) two door unit. But I think you may be right in that the invertor powering that unit. I will have to see if there is anything else being powered by it.

Iggy, I am the 3rd owner, and one of the previous owners must have installed it. I have this switch that only says "ON", so I am slowly coming to the realization that it is my invertor. I cannot figure out what else it would be.

Apparently there are some who install inverters so that LP/AC reefers can run from battery when on the road in order to conserve propane and due to safety considerations. I recall reading such a thread a while ago. Personally it is a strange idea as the AC features of a LP/AC unit are not that good and running an inverter to power a heating element sounds strange to me...but everyone is entitled to their own opinion.

If setup correctly and it's an inverter, you should find dedicated outlet (s) or a sub panel with the inverter powering it; many good ones cut 120vac through when on Genny or shore power, with a built in transfer switch. tell us more about it... brand ... watt rating... photos are nice. Probably installed to run or charge low watt items so you don't have to run the genny but still need 120vac... like a CPAP.

I am in the process of installing an inverter in our 2015 GT310 DS. We acquired this RV just 6 months or so ago after operating a Safari Trek for ten years. The Trek came with an inverter. We use the inverter for a number of items, the crock pot when driving, PC router while on the road, and yes we dry camp and I do not want to be a noisy neighbor.

I am still investigating what is all on the invertor, so as I get a chance I will update. I did find out last night that my retracting stairs are on it. They don't run unless my invertor is on. Keep the feedback coming!

No way! Your stairs are DC operated. Perhaps your disconnect switch is turned off and you are referring to your "converter" which makes 12 volts from shore power, or you have a combination inverter/converter (Magnum and others)

I think what you are referring to as an inverter on switch is your battery disconnect switch. I believe you have the Lippert steps and the battery disconnect switch must not have the battery disconnected for your steps to retract. The step power switch needs to be on also. Please post a picture of this mystery switch.
