Contemplating an inverter on your motorhome or campervan? Undecided what measurement you want or which is greatest? Don’t worry- right here’s all the pieces you must learn about selecting the perfect motorhome inverter for you.

Motorhome inverters- the fundamentals
I’ll be trustworthy, I don’t actually ‘get’ electrics. And I undoubtedly don’t get something which entails enjoying round with motorhome energy methods and batteries which may kill me if (when!) I get it unsuitable.
Nonetheless, ever since our very first motorhome, we’ve agreed an inverter is an important piece of equipment for the best way we use the van, so, when my final one broke (my fault!), I wanted to get a brand new one.
So, the primary query is: why?
Do you want an inverter in your van?
Most individuals who use campsites usually in all probability don’t must hassle about becoming an inverter of their motorhome or camper. In any case, the concept of it’s to vary 12v energy from the leisure battery into 230v energy which can be utilized to energy home equipment like laptops and hairdryers.
So, for those who already primarily use campsites and their energy provide, you’ll be able to already energy/ recharge these gadgets.
Nonetheless, we LOVE motorhome wild tenting/ parkups. We like staying off-grid, or utilizing aires in France, or staying in forestry automotive parks.
None of those have energy out there, so we should be self-sufficient. While the motorhome can survive for a number of days off-grid, gadgets like my laptop computer (which this complete motorhome weblog was constructed on) or our drone, or our Ecoflow energy station, all want topping up to ensure that us to proceed to spend time off-grid.

We additionally tour with motorbikes, and infrequently use the inverter to recharge our helmet intercoms or our heated clothes battery packs.
For that purpose, for us, it’s a van life important and permits us to be far more versatile quite than needing campsites on a regular basis. (See extra motorhoming necessities right here.)
What measurement inverter do you want in a motorhome or campervan?
Ha, isn’t that the necessary query!?!
In contrast to diesel engines, you don’t need to work an inverter exhausting. You really need there to be some wiggle room.
Nice, so simply purchase the largest one the market?
Nope- coz that’s a)- costly and b)- will drain your leisure battery tremendous quick. There must be a bit extra thought into what measurement inverter you must match.
Inverters are usually not 100% environment friendly. In actual fact, for many inverters, you’ll be able to anticipate about 80-85% effectivity. Due to this fact, to know the scale you want, take the biggest equipment you need to energy from the inverter, see what it attracts (enter energy), then be sure to add no less than 20%- that’s the scale inverter you want.
There are two forms of energy you’ll see on an inverter- steady energy output and peak energy output.
Peak energy is short-duration, often on start-up. Steady is… steady. That is the quantity you must take a look at if you’re choosing one to buy.
My first inverter was 300w. As you’ll be able to see within the video, it wasn’t sufficiently big to do what I wanted it to do. The brand new one is 2000w!
That is the one I fitted not too way back:

Motorhome inverters- Pure sine or modified sine?
Okay, for those who perceive electrics look away now, as a result of that is in all probability extra primary then you definately need it to be.
A pure sine wave provides a easy voltage curve, which is what most home equipment are designed to run on. A modified sine wave has ‘steps’ the place the facility will increase or decreases in jumps. These jumps in voltage may cause issues with delicate electrics, like laptops, TVs, espresso makers, energy stations and CPAP machines. It might probably additionally trigger overheating of transformers and chargers.
Nonetheless, they’re usually superb to energy issues like hairdryers, energy drills, battery packs and so on.
As a result of they’re not as refined, modified sine wave inverters are MUCH cheaper to purchase than pure sine.
NOTE: Should you’re shopping for off Amazon or on-line, many abroad locations state their system is pure-sine when it’s not. Do your analysis fastidiously. You may see the one we bought within the Youtube hyperlink above.
Becoming an inverter in a motorhome
Right here’s how we fitted our new inverter in our motorhome. It wasn’t too tough BUT, for those who’re in any manner uncertain, please ask an expert to assist so that you don’t damage your self or harm your methods.
Ideas for becoming a motorhome inverter
Listed here are some suggestions that can assist you:
- Don’t let something contact the battery terminals collectively
- Disconnect the adverse first and connect the adverse final.
- Inverters are essentially the most current-heavy objects you’ll be able to connect to a 12V battery. Use a lot of fuses as security breakers.
- Fashionable battery cables have the continual present ranking marked on them – make sure that your fuse by no means exceeds these ranking.
- Ensure that the wires/ leads are the right gauge. Some inverters are equipped with cheaper leads which aren’t robust sufficient to do the job.
- Some small inverters could be powered from a 12V cigarette socket. DON’T plug thes into the socket within the cab as that’s powered by your car battery and can drain it. Solely use it from sockets within the hab space that are powered out of your leisure battery.
- Keep in mind that simply because it may be powered by a cigarette lighter, doesn’t imply the cigarette lighter in your van is powerful sufficient to energy it; a 120W inverter can draw round 10A, which can doubtless blow a cigarette-lighter fuse at full energy.
- Attempt to place the inverter as near the leisure battery as attainable to maintain the cables quick (max 2m for any inverter over 2000w). This reduces the temperature and voltage drop within the cables.
- If this isn’t attainable, improve the diameter of the cables.
Video of us becoming an inverter in our motorhome
Right here’s a video of us becoming an inverter in our motorhome.
NOTE: I forgot to incorporate the essential clip of us placing a fuse on the constructive. Should you’re unsure how to do that, please ask an expert.

Tips on how to use a motorhome inverter
The simplest manner to make use of a motorhome invertor is to plug your system or equipment straight into the 230v 3-pin plug socket really on the inverter.
Alternatively, you should utilize an extension result in make it simpler to entry, however don’t overload the inverter with an excessive amount of.
It’s actually difficult to get an inverter to run the prevailing 3-pin sockets within the habitation space of your motorhome, so attempt to keep away from pondering of it like that.
We ONLY use our inverter while we’re driving. This permits us to cost gadgets prepared to be used once we cease AND stops us from by accident draining the leisure battery. We additionally by no means use it for longer than an hour and it’s not often operating at something near full energy.
How lengthy will an inverter run off a motorhome battery?
Like all the pieces else, this may depend upon the scale of the inverter, the scale of your motorhome leisure battery/ batteries and the scale of the system(s) you’re powering.
Nonetheless, to provide you an concept, a 2000w inverter (just like the one we put in), operating at FULL POWER (which is unlikely for an extended interval), might flatten a 100A motorhome leisure battery in 36 minutes.
Right here’s the maths:
- 2000w/ 12v= 166.6 amps/ hour
- 100ah battery/ 166.6= 0.6 hours (36 minutes)
BUT- you don’t need to flatten your battery, so in actuality you solely have about 18 minutes of full-power use earlier than you must cease. That is one more reason we solely use the inverter while driving AND solely after we’ve been driving some time, so the battery has had time to get no less than slightly bit recharged.
In the best way WE use the motorhome, an inverter is crucial. But it surely’s not for everybody. Earlier than you lay out on one, be sure to suppose it’s one thing you’ll undoubtedly want.
