Can You Plug An RV Into A Solar Generator/Power Station?

Plug Your RV or Trailer Into A Solar Generator

Would you like to boondock and be able to watch TV and use your toaster or microwave, without having to run a noisy gas generator outside? This is possible because you can plug a solar generator/power station directly into your RV camper.

Run a camper on a solar generator

You can plug a camper into a solar generator, and I know this since I do it myself as I’ll talk more about down below.

Whether it’s possible or not with a specific solar generator depends on how many watts its inverter can handle. If your 12V batteries are not full, as soon as you plug the camper into the solar generator, it’s going to start charging the 12V batteries (amongst other things plugged into your trailer outlets). This can use between 100-500 watts.

Therefore I recommend a solar generator with at least a 500W inverter, although higher is to prefer.

How I use my solar generator with my camper

My wife and I travel fulltime in a travel trailer, and our setup is a Goal Zero Yeti 1000 and 400 watts of solar panels. We boondock 95% of the time, our Yeti and solar panels cover 90% of our energy needs.

The Goal Zero Yeti 1000 is a solar generator, also known as a portable power station, that has a 100Ah lithium battery, a pure sine wave inverter, and a solar charge controller which lets me plug my solar panels directly into it.

The Yeti 1000 has an inverter that changes the 12V DC power into 120V AC power, and it powers several AC outlets on the Yeti, this is where I plug my camper in.

Goal Zero has put a 1500W/3000W surge watts pure sine wave inverter in this unit. Which means that I can use electronics that use up to 1500W. Here are a couple of the things I use in my travel trailer and an estimate of how many watts they use.

We don’t run the water heater or fridge on electric since that would drain the battery quickly, and that’s not worth it.

Since the Yeti has 1045 watt-hours to work with, I could, for example, run my gaming laptop for at least six hours straight (1045/150). Note that an inverter has an efficiency rate of about 90%, so the most realistic calculation to do is 1045*0.9 and then split it with 150W (how much my gaming laptop uses every hour while I am gaming) which equals 6.27 hours.

My solar panels are two portable Renogy 100W suitcases I plug into the Yeti with the help of an adapter. They’re combined with an MC4 Y branch connector.

In addition to my portable solar panels, I also have two Renogy 100W solar panels on top of my camper.

These panels generate about 120 amps combined on a sunny day even during the winter months, which means that my Yeti 1000 can go from empty in the morning to fully charged in the afternoon. I wish I would’ve bought one of the bigger models so I could store more power for cloudy days since I usually bring in more watts than I use on sunny days, resulting in the battery being fully charged even while I am using it, wasting excess power.

Another great feature with the Yeti 1000 is the screen that tells me how many watts I am generating with my solar panels, and how many watts I am using through not only the AC outlets, but the USB ports and 12V cigarette plug found on the unit.

What the Yeti 1000 can run in my travel trailer

The Yeti runs everything in my camper, except for the AC compressor. I haven’t tried because I don’t want to trip the Yeti, but I know that a 13,500 BTU air conditioner requires more power than the Yeti can output.

It also couldn’t run my 900W microwave, but I have since gotten a Comfee 700W microwave that it runs just fine. My 700W microwave requires about 1100 watts to run, so it’s within the limits.

Being able to heat leftovers in the microwave when we’re boondocking without running a gas generator is awesome.

We use our furnace, toaster, egg cooker, George Foreman, watch TV, charge our laptops all day, vacuum, and charge all of our devices without any issues.

Do you leave your power station outside?

You could put your power station outside or in one of the storage compartments and pull the 30A/50A cable to it, but what I have done lets me keep the power station in the trailer, so I can monitor and turn on/off the outlets as I need. This also lets me use the Yeti on rainy days without me having to go outside or worry about it getting wet.

What I did was split into the 30A cable going to the 30A plug where I plug my trailer in when I need to use the gas generator or plug into a camping ground.

The plug is located in the back of my trailer, where I have a bunk bed. So I can access the inside of the plug by lifting up the bottom bunk. This is where I cut the 30A cable in half and put a 30A plug and a 30A receptacle. The 30A plug is on the cable coming from the trailer, and the receptacle is on the wire going to the 30A outlet outside. I basically added a quick disconnect between the electrical control panel in my trailer and the 30A plug.

So what I can then do is use the 15A to 30A, plug the adapter into my trailer, then run a regular AC extension cord from the adapter to my power station and plug it into one of the outlets on the Yeti.

How my cables are set up when I want to plug the trailer into my power station.

Here is how it’s set up under my bunk bed when I have the trailer plugged into the Yeti 1000.

  1. The 30A receptacle, this wire goes to the 30A plug located on the outside of my camper. When I want to plug it into a gas generator or campground, I grab the adapter (3 in the image) and connect 1 and 2 together.
  2. The 30A plug coming from my trailer’s electrical system. 1 and 2 used to be a solid connection, but I cut into it and installed the 30A plug and 30A receptacle.
  3. The 15A to 30A adapter that turns the 30A plug into a regular 15A cable.
  4. My AC extension cord, this cord goes straight to the Yeti 1000 and is plugged into one of the outlets on the power station. Now the Yeti powers my travel trailer.

If I want to plug my camper in using the 30A outlet outside on the back of my camper, I unplug the 15A to 30A adapter and connect 1 to 2 to make the connection. Then I either plug a 30A cable into the trailer and the campground’s power grid, or I take the adapter outside and plug it into my gas generator.

What About Your Solar Panels?

We have two portable panels and two panels on our roof.

The panels on the roof are wired in parallel so we only have one positive wire and a negative one. These wires are pulled down through the refrigerator vent that’s on the roof. We did it this way because we didn’t want to drill any large holes in the camper roof.

We did have to drill two holes to get the wires to the Yeti. One from the outside and one from the inside. The one outside is behind the fridge and was easy to do after removing the fridge vent cover.

After pulling the wires through, we covered the hole with Great Stuff Gaps & Cracks foam just in case any water would get in behind the fridge.

This lets us pull the wires down underneath the fridge, which is where our furnace sits, and if you’re going to do a similar setup you might have to do it differently depending on the layout of the camper.

The second hole, inside, is just to get the wire from where the furnace is to our Yeti. We drilled a hole in the furnace cover because we didn’t have enough space to do it anywhere else.

The wires for our portable panels come in through one of our storage compartments under our bunk, so we had to drill two more holes to get those wires to the Yeti. We didn’t want to drill a hole on the side of the trailer, so we keep the 30ft MC4 cables in the storage compartment until we get to a campsite, then we pull out the panels and the wires.

We had a couple of smart mice that climbed the MC4 cables and came into the storage compartment, so, the last thing we did was to put steel wool in the holes around the wire, and that has kept the mice away.

So do you have a gas generator?

We do have a gas generator, it’s a small and quiet WEN 56200i generator. If it’s cloudy for a couple of days, we bring it out to recharge our Yeti. The Yeti comes with a 5A wall charger so you can recharge it from a regular outlet.

Goal Zero recently released a much faster 25A wall charger that you could plug into a gas generator and recharge the Yeti 1000 in four hours.

When needed, I can still use my 30A outlet on the back of my trailer.

You can also recharge the Yeti in a car from a 12V cigarette plug.

How long does a solar generator last?

It depends on how big the battery in the solar generator is, and how many watts you’re using. For example, in my Yeti 1000 I have 1045 watt-hours to work with. If I charge my laptop that uses 60W for an hour, I have about 985 watt-hours left to work with (1045-60).

The inverter that changes 12V DC to 120V AC is not 100% efficient, so when you use the AC outlets on a solar generator you should expect about 90% to be energy you can use in the end.

If you want to figure out how much power your RV camper, or electronics use, you can plug it into an outlet through a Kill A Watt which will tell you exactly how many watts the device is drawing.

How do you plug in an RV camper to a regular 15A outlet?

My trailer has a 30A plug, so I use a 15A to 30A cableLeisure Cords also sell a 15A to 50A adapter in case your trailer has a 50A plug.

If you plug your camper into a gas generator, you could put the Kill A Watt mentioned above between the connection to figure out exactly how many watts you’re using as it is, so you know how strong the inverter in a solar generator needs to be to fit your needs.

What is the best solar generator for RVs?

If you’re considering a solar generator for your camper, I recommend one that has at least a 1000W inverter. Then you would be able to run everything in your RV except for the microwave and the air conditioner.

A great one if you’re ok with not using the AC or microwave with a lot of power is the Maxoak Bluetti 2400Wh. 2400Wh is more than twice the battery in my Yeti, and it would run a 50W TV for almost two days straight.

I am extremely happy with my Goal Zero Yeti 1000, and there are even bigger models available like the Yeti 1400 and Yeti 3000. Both of the latter can be controlled and monitored through a phone app if you have a Wifi setup for it to connect to, which is a pretty neat feature.

I have compared the Yeti 1000 and Yeti 1400 in a separate post that you can find here.

There is also the inergy Apex which has a 30A plug. I have written about the Apex in a separate post you can find here. You can buy the Apex in a kit with several solar panels depending on how much you need. Note that the 30A won’t allow you to run an air conditioner, but will probably run your microwave.

Another one is the Renogy Lycan which is similar to the two above in size, from the same company that makes popular solar panels. You can save 10% if you shop from Renogy’s website my link. Disclaimer: I earn a percentage on the sale, but it doesn’t cost extra for you. (*Excludes GEL/AGM batteries and sale items.)

What size solar generator do I need?

The easiest way to answer this question is by writing down each device and how many watts it uses. You can read on the device or its charger how many watts it uses, or use a Kill A Watt that will tell you exactly.

So if your computer uses 60 watts, and you want to use that for 5 hours a day, you’re going to need at least a 300Wh battery (60*5). Do this kind of calculation with all of the devices you intend to use, and you’ll get a better understanding of how many watt-hours you use and what size solar generator you’re going to need.

How many watts each device uses is also relevant because the solar generator has an inverter that has to be able to run that device.
