Motorhome inverters- the fundamentals
I’ll be trustworthy, I don’t actually ‘get’ electrics. And I undoubtedly don’t get something which entails taking part in round with motorhome energy methods and batteries which might kill me if (when!) I get it incorrect.
Nonetheless, ever since our very first motorhome, we’ve agreed an inverter is a vital piece of package for the way in which 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 repeatedly most likely don’t must hassle about becoming an inverter of their motorhome or camper. In spite of everything, the thought of it’s to alter 12v energy from the leisure battery into 230v energy which can be utilized to energy home equipment like laptops and hairdryers.
So, in case you already primarily use campsites and their energy provide, you’ll be able to already energy/ recharge these units.
Nevertheless, we LOVE motorhome wild tenting/ parkups. We like staying off-grid, or utilizing aires in France, or staying in forestry automobile parks.
None of those have energy out there, so we have to be self-sufficient. While the motorhome can survive for a number of days off-grid, units like my laptop computer (which this whole 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 cause, for us, it’s a van life important and permits us to be rather more versatile reasonably 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 essential query!?!
Not like diesel engines, you don’t wish to work an inverter laborious. You truly 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 want to match.
Inverters usually are not 100% environment friendly. In truth, for many inverters, you’ll be able to anticipate about 80-85% effectivity. Subsequently, to know the scale you want, take the most important equipment you wish to energy from the inverter, see what it attracts (enter energy), then be sure to add at the least 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, normally on start-up. Steady is… steady. That is the quantity you want to have a look at if you’re selecting one to buy.
My first inverter was 300w. As you’ll be able to see within the video, it wasn’t large enough 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, in case you perceive electrics look away now, as a result of that is most likely extra fundamental you then need it to be.
A pure sine wave provides a clean 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 could 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.
Nevertheless, they’re typically tremendous 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: For those who’re shopping for off Amazon or on-line, many abroad locations state their gadget is pure-sine when it’s not. Do your analysis rigorously. You may see the one we acquired 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 troublesome BUT, in case you’re in any manner not sure, please ask an expert to assist so that you don’t damage your self or injury your methods.
Ideas for becoming a motorhome inverter
Listed below are some ideas that can assist you:
- Don’t let something contact the battery terminals collectively
- Disconnect the adverse first and connect the adverse final.
- Inverters are probably the most current-heavy gadgets 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 score marked on them – be certain your fuse by no means exceeds these score.
- Be sure that the wires/ leads are the proper gauge. Some inverters are provided with cheaper leads which aren’t robust sufficient to do the job.
- Some small inverters will 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 robust sufficient to energy it; a 120W inverter can draw round 10A, which is able to seemingly blow a cigarette-lighter fuse at full energy.
- Attempt to place the inverter as near the leisure battery as potential to maintain the cables brief (max 2m for any inverter over 2000w). This reduces the temperature and voltage drop within the cables.
- If this isn’t potential, enhance 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 crucial clip of us placing a fuse on the constructive. For those who’re undecided how to do that, please ask an expert.
We hope you discovered the video helpful. For those who did, we’d adore it if you adopted us on Youtube. New movies with ideas for motorhoming and campervanning within the UK and Europe are launched weekly.
Learn how to use a motorhome inverter
The simplest manner to make use of a motorhome invertor is to plug your gadget or equipment straight into the 230v 3-pin plug socket truly on the inverter.
Alternatively, you need to use 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 present 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 enables us to cost units prepared to be used once we cease AND stops us from unintentionally draining the leisure battery. We additionally by no means use it for longer than an hour and it’s not often working at something near full energy.
How lengthy will an inverter run off a motorhome battery?
Like every thing else, this may rely upon the scale of the inverter, the scale of your motorhome leisure battery/ batteries and the scale of the gadget(s) you’re powering.
Nevertheless, to provide you an concept, a 2000w inverter (just like the one we put in), working at FULL POWER (which is unlikely for a protracted 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 wish to flatten your battery, so in actuality you solely have about 18 minutes of full-power use earlier than you want to 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 at the least a bit of bit recharged.
In the way in which 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 assume it’s one thing you’ll undoubtedly want.
