Motorhome inverters- the fundamentals
I’ll be sincere, I don’t actually ‘get’ electrics. And I positively don’t get something which includes taking part in round with motorhome energy methods and batteries which may kill me if (when!) I get it incorrect.
Nonetheless, ever since my very first motorhome, I’ve mentioned an inverter is an important piece of equipment for the way in which I exploit 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 most likely don’t have to hassle about becoming an inverter of their motorhome or camper. In any case, the thought 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, when you already primarily use campsites and their energy provide, you’ll be able to already energy/ recharge these units.
Nonetheless, I LOVE motorhome wild tenting/ parkups. I like staying off-grid, or utilizing aires in France, or staying in forestry automobile parks.
None of those have energy obtainable, so I must be self-sufficient. While the motorhome can survive for a number of days off-grid, units like my laptop computer (which this complete motorhome weblog was constructed on) or drone, or the Ecoflow energy station, all want topping up to ensure that me to proceed to spend time off-grid.

For that purpose, for me, it’s a van life important and permits me to be rather more versatile reasonably than needing campsites on a regular basis. (See extra motorhoming necessities right here.)
What dimension inverter do you want in a motorhome or campervan?
Ha, isn’t that the necessary query!?!
Not like diesel engines, you don’t wish to work an inverter onerous. You truly need there to be some wiggle room.
Nice, so simply purchase the most important 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 dimension inverter it’s worthwhile to match.
Inverters are usually not 100% environment friendly. The truth is, for many inverters, you’ll be able to count on about 80-85% effectivity. Subsequently, to know the dimensions you want, take the biggest equipment you wish to energy from the inverter, see what it attracts (enter energy), then be sure you add at the very least 20%- that’s the dimensions inverter you want.
There are two sorts 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 it’s worthwhile to take a look at while 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, when you perceive electrics look away now, as a result of that is most likely extra primary then you definately need it to be.
A pure sine wave offers a easy voltage curve, which is what most home equipment are designed to run on. A modified sine wave has ‘steps’ the place the ability 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 will probably additionally trigger overheating of transformers and chargers.
Nonetheless, they’re usually high-quality 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: When you’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’ll be able to see the one I received within the Youtube hyperlink above.
Becoming an inverter in a motorhome
Right here’s how I fitted the inverter in my motorhome. It wasn’t too troublesome BUT, when you’re in any method uncertain, please ask an expert to assist so that you don’t harm your self or harm your methods.
Suggestions for becoming a motorhome inverter
Listed below are some suggestions that can assist you:
- Don’t let something contact the battery terminals collectively
- Disconnect the damaging first and fasten the damaging 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.
- Trendy battery cables have the continual present ranking marked on them – be sure that your fuse by no means exceeds these ranking.
- Be certain that the wires/ leads are the right gauge. Some inverters are equipped with cheaper leads which aren’t sturdy 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 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 brief (max 2m for any inverter over 2000w). This reduces the temperature and voltage drop within the cables.
- If this isn’t attainable, enhance the diameter of the cables.
Video of us becoming an inverter in our motorhome
Right here’s a video of becoming an inverter in my motorhome.

The way to use a motorhome inverter
The simplest method 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 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 sophisticated 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.
I ONLY use the inverter while I’m driving. This enables me to cost units prepared to be used once I cease AND stops us from by chance draining the leisure battery. I 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 things else, this can rely on the dimensions of the inverter, the dimensions of your motorhome leisure battery/ batteries and the dimensions of the gadget(s) you might be powering.
Nonetheless, to present you an thought, a 2000w inverter (just like the one I put in), operating 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 it’s worthwhile to cease. That is another excuse I solely use the inverter while driving AND solely after I’ve been driving some time, so the battery has had time to get at the very least slightly bit recharged.
In the way in which I exploit the motorhome, an inverter is crucial. But it surely’s not for everybody. Earlier than you lay out on one, be sure you assume it’s one thing you’ll positively want.
