Inverter Install - Solitude 3540GK

**dagerlach** · 08-07-2022, 05:15 PM

Purchased at 3540GK, pulled the Norcold out and put in a Samsung residential fridge. I'd like to install an inverter to run the fridge while driving.

Question:

1. Is the RV wired for the factory inverter?

2. Can I just purchase the inverter that would have come with the residential model and install it?

I plan to put in a Victron system, but am wondering if I can do a quick mod before diving into a big project this fall.

Thoughts?

Thanks,

David

David,
#1 : I cant speak for your how your trailer is configured.
#2 : I doubt it will be that simple. Much goes in to planning an inverter system, just for starters:
- AC power requirements
- DC power requirements
- number of batteries
- hours needed while running the inverter
- Battery Ah
- Inverter size
- cabling

Throwing some batteries together with an inverter may run your refrigerator for a short time. It also may burn down your trailer. Best to plan it out and insure it will meet your needs and be a safe system.

It's pretty simple to put in a 1000 watt inverter just for the fridge.

Assuming you already have a 120v circuit for the residential refrigerator you installed just plug the inverter into that, connect the inverter to your battery(s) and run and output 120v circuit from the inverter to plug your refrigerator into.

When you get around to the whole Victron system, etc. you can figure out sizing, sub panels, solar, whatever for your ultimate set up.

I also sent you a PM.

oh - btw..... Welcome to the forum. You'll get lots of good info and advice here from folks who have lived through what you are starting to do.

If you're talking about a complete solar and battery system using Victron and/or other components, then any "quick mod" will likely end up being money wasted. As Ken said, there are a number of factors to consider. IMO you would be better off waiting until you're ready to do the full project. There are several threads on this forum that cover how people have installed systems like the one you're contemplating.

BTW, although you've been around the forum for a while, it looks like this is your first post. Welcome aboard. Keep us informed (pictures are good) about where you ended up going.

I usually go overkill. I would rather get a larger inverter than I need. Nothing wrong with buying something twice as large as you need. I would rather see a product running at half load than something running full load all day long.

Inverters usually need a fair size 12v cable for it to run. I cannot see a Manufacturer adding that kind of cable. It's expensive.

The downside is that larger inverters waste more 12V when in standby.
My 2000 watt seems to draw about 5 Amps in standby, so it can add up.
I did install a second switch inside so I can turn it off without going outside, when it is not needed. But in real use, it is usually on.

Isn't that what the inverter off switch is for? I grew up in a household that you did not leave the lights on if you were not in the room. Simple to turn off the inverter when not in use. I guess the biggest issue is the microwave clock.

That is the great thing about opinions. You weigh the pros and cons and then find out what is best for you.

Yes that is why I brought up the switch relocation... I just thought that some may not know that the larger the inverter, the more inefficient it is.

All,

Completed the project about a month ago and took the RV on a 3 week trip to Bar Harbor/Acadia. I’m happy to say everything worked perfectly. Now, on to creating a larger system w/ solar. Fun project and the wife is happy with a fridge that actually works.
