Motorhome Mills- do you even want one?
Okay, let’s begin with the obvious- do you even NEED a generator in your motorhome?
Trustworthy reply?
No, you in all probability don’t. However you may want one…
When would possibly you utilize a generator in your motorhome or campervan?
The purpose of most motorhome mills is as a backup energy unit, so it’s there if you really want it. When you plan to spend most of your motorhome holidays utilizing campsites, you’ll hardly ever have a chance to make use of a generator in any respect.
Even for those who favor to make use of aires or permitted motorhome parkup spots, most of them aren’t locations you possibly can comfortably use a generator.
When you favor off-grid parking/ wild tenting together with your motorhome, it’s additionally probably that you simply received’t use a generator fairly often, particularly when you have one other solution to high up your leisure battery- like a photo voltaic panel.
Heck, within the 3 years I had one, I solely used it a handful of instances, so it actually shouldn’t be high of your important motorhome equipment to purchase record.
BUT… it’s these instances if you REALLY want to spice up your motorhome batteries, particularly for those who keep off-grid rather a lot, if you would possibly profit from having a gen-set on board.
Having mentioned that, it’s NOT one of many essential issues you must go motorhome wild tenting, so don’t suppose you want one so as to have the ability to keep away from campsites- that’s not the case.
Do I exploit a generator in my motorhome?
As I discussed above, I carried a motorhome generator for 3 years. It was cumbersome, it was heavy and I might by no means begin the factor.
And, EVERY SINGLE TIME I used it was so I might cost our laptops.
So, I’ve now traded the generator for a transportable energy financial institution, which fits my wants significantly better. I additionally don’t keep in a single place for a number of days, which is when a generator turns into invaluable.
Right here’s the best way to determine if a generator or a powerbank is greatest for you:

What’s the greatest transportable generator for a motorhome or tenting?
I’m a agency believer in there hardly ever being one ‘greatest’ product for everybody. And it’s the identical for motorhome mills.
Having mentioned that, there are a couple of I like to recommend for varied causes all through this put up. When you’re in a rush, right here’s a round-up:
Professionals and Cons of getting a motorhome generator onboard
After a couple of months with a van, again then, all these years in the past, I realised I favor motorhome wild tenting/ off-grid parking. And I like staying up mountains/ in forests/ in the midst of nowhere. And I like to try this for so long as bodily attainable.
I additionally work as I journey, so I would like methods of recharging our laptops, telephones, iPads (to not point out my beloved journey drone)
I’ve a photo voltaic panel which helps high up the motorhome leisure battery, however there have been a couple of instances the place I’ve wanted a bit of serving to hand. A bit ‘increase’ to assist cost the units which might’t be powered by 12v (like my Macbook Professional earlier than the 12v charger).
Don’t overlook, for those who don’t have mains energy, you received’t be capable of use any 240v/ 230v units (3-pin plug), like a hairdryer, microwave, electrical kettle or charger. With a generator of adequate output, you possibly can.
In order that’s the most important professional of getting a generator in your motorhome- it permits you to get energy for stuff you want if you in any other case can’t. For me, it was invaluable earlier than the ability banks grew to become a factor, like Ecoflow and Jackery.
Cons of a motorhome generator
There are a number of downsides to carrying a generator onboard your motorhome or camper:
- Preliminary price
- House- discovering someplace to retailer it
- Weight- it eats into your motorhome payload
- Having to hold gasoline for it
- Upkeep
- Noise
All of this stuff are large causes to not purchase a generator- and so they’re legitimate causes. I solely acquired one (a few years in the past now) when going motorhoming in Norway and knew I wished to keep away from campsites for so long as attainable.
Nonetheless, for those who’re nonetheless satisfied you need a generator to your motorhome or campervan, right here’s how to decide on the best choice for you.
How to decide on the suitable motorhome generator for you
Let’s be sincere, most of us are conditioned to suppose that larger is healthier (no sniggering within the again row please… ?) Nonetheless, identical to I found there have been some large downsides to a motorhome over 3.5tonnes, I additionally realise that you simply don’t want to purchase the most important transportable generator attainable, even for those who can match it right into a locker and also you magically have the payload to spare.
There are a number of issues to search for:
- Bodily measurement
- Weight (each to raise AND in the direction of your motorhome payload)
- Energy output stage (and frequency) – UK is 230v/ 50hz
- Noise output stage
- Gasoline sort
- Socket sort
- Beginning technique (I HATE pull begins, though that’s what I had- however button begins are a lot simpler!

What measurement generator do you want for a motorhome?
There are two forms of measurement to consider- the bodily measurement of the genset, and the quantity of energy it produces.
Bodily measurement
Bodily measurement is pretty obvious- does it match the place you need it to go when it’s being saved? Whether or not you must put it below a seat (as I did), otherwise you’re fortunate sufficient to have a motorhome with a storage or exterior storage locker, you must make sure that it’ll bodily match the place you need.
Don’t overlook to contemplate peak, in addition to width and depth- many potential motorhome mills are too tall to go below a seat, particularly with a cross beam.
I additionally don’t advocate a generator with wheels, because it takes up an excessive amount of room. Nonetheless, when you have a storage, you would possibly favor a kind with wheels so it’s simpler to maneuver, particularly when you have a ramp.
Weight
The opposite factor to consider is the burden. The weight & payload of your motorhome is an apparent consideration, however so if the actual fact that you will want to raise it out and in of your motorhome or camper. If it’s too heavy, you’re both going to injure your self, or by no means ever use it as a result of it’s too heavy to get out- which defeats the purpose of shopping for it.
As a (very) tough information, a 1000w mannequin weighs about 15kg, however a 2000w generator might weigh over 20kg.
Energy Output- how large do you want?
So, how a lot energy do you want in a motorhome generator? What measurement is adequate?
The plain reply is ‘the one which lets you run and use no matter you need to run and use’. When you simply need to high up your leisure battery, or give telephones/ iPads a fast cost, you may get away with as little as a 1kw generator.
If you wish to use something which is over 1000w in energy (take a look at the label on the gadget), then you definitely’ll want a generator able to dealing with that. For instance, many hairdryers are 1800w. To run one, you’d want a generator of at the least 1800w PLUS make sure that so as to add a bit (round 20%) for resistance and different masses. I
f you’re planning to make use of your generator for one thing with shifting elements (like a stress washer), you must add even more- round 50%
NOTE: Many transportable mills have a ‘most’ wattage and a ‘fixed or steady wattage’ worth. This implies it could deal with a better load for a brief time frame (while beginning up an air con unit or van heater for instance), however then it must drop right down to a operating stage. So take a look at the continual or operating wattage as the primary determine for extended use. There’s an amazing put up right here that offers you a information to some widespread energy utilization charges (keep in mind every equipment differs so you’ll want to verify your labels.)
Additionally, don’t overlook the generator wants sufficient energy to run a number of issues directly. It’s extremely unlikely you’ll JUST run a hairdryer. You would possibly use the time it’s on to cost electronics, watch TV, cool the fridge, run the air-con, or use the microwave. Make sure that to account for all this- or keep in mind to show one factor off earlier than utilizing one other.
However, after all, the larger the wattage, the heavier and greater the generator normally is- so it’s all a trade-off. When you want a generator for tenting, you must make sure that the burden isn’t so heavy you possibly can’t raise it.
You additionally must verify the frequency. Most UK mills are 50Hz (UK commonplace). That is essential for utilizing home equipment like motorhome TVs, so you’ll want to verify any gadget you would possibly need to use with the generator, particularly if it’s not a UK equipment with a UK generator.
Pure Sine Wave/ Inverter
When you’re planning to energy one thing which wants a easy energy, get one thing with both pure sine wave or inverter energy. (Nope, I’m not an electrician and I’m not even going to attempt to clarify that. All you must know is that they supply ‘easy’, fixed energy, so delicate units like sport consoles, TVs, laptops and many others don’t break resulting from an influence surge or dip. When you’re an electrician, be happy to depart a remark under explaining that higher! 🙂 )

How noisy are motorhome mills?
Okay, this is without doubt one of the greatest issues to contemplate when selecting the most effective motorhome generator. After all, you’ll primarily be utilizing it in the midst of nowhere, however the quieter it’s, the extra discreet you’ll be.
Don’t consider the ‘silent generator’ hype you hear- ALL mills are engines and make some sort of noise. Loud noise. Ours is pretty quiet (in comparison with others I’ve skilled) and it’s nonetheless fairly loud, particularly if you’re outisde.
In case you are planning to make use of your generator close to different vans, I aways advocate utilizing it throughout daytime AND asking the opposite vans close by first. A bit politeness by no means hurts. Most campsites don’t permit mills to be run throughout evening hours.
I like to recommend placing your generator in a sheltered spot, ideally a bit of means away out of your camper (if attainable) and ideally behind a wall or some rocks- makes it quieter for everybody. Having mentioned that, pay attention to security- mills are enticing to thieves so don’t put it too distant and be alert while utilizing it. Don’t go away it outdoors in a single day.
What’s the quietest transportable generator for tenting?
As you possibly can see under, there are a few mills I like to recommend that are below 60db (which is about as loud as background dialog in a restaurant.)
The quietest I’ve heard good issues about are:
Compatibility
Most UK vans use 230v/ 50hz and require a dwell, impartial and earth. In case your generator just isn’t created for the UK market, it might have totally different ranges, which you then must verify are suitable each with the home equipment AND the ability unit in your motorhome or campervan.
Utilizing a generator not suitable together with your automobile might invalidate the warranty- and may even trigger a hearth within the motorhome.
NOTE: Many transportable mills wouldn’t have a separate earth, which might trigger some programs to state their is a fault. Seek the advice of the handbook or contact the producer if this occurs to you.
Socket Kind
The generator may have a number of sockets. These are prone to embrace both a UK 3-pin plug, or a motorhome energy socket. Some even have 12v sockets for charging units.
IMPORTANT: Generally, these sockets are NOT waterproof, so don’t use or go away your generator within the rain or damp situations.

Listed below are another good options:
Does Gasoline sort matter for tenting mills?
Not likely. No matter gasoline it makes use of will likely be one thing you’ll want to hold a small can of (in an permitted container!) Keep in mind, you possibly can usually retailer propane for an indefinite time, whereas diesel has a shelf lifetime of between 6 and 12 months and unleaded solely about 6 months in an unsealed container.
Does it have to evolve to EU5 or EU6 requirements?
This is a superb query: for those who’re shopping for a brand new motorhome generator, does it want to evolve to EU5 or EU6 requirements? There are transportable mills available on the market which proudly state their conformance, however they at present price WAY greater than others on the market- is it value the additional cash and do you NEED to purchase one?
Clearly, in an excellent world, we’d all purchase engines which assist cut back emissions and conform to the brand new requirements. However, identical to it’s nonetheless authorized to purchase a automotive which doesn’t conform, it’s nonetheless authorized to purchase an occasional-use generator which doesn’t verify.
Personally, I don’t consider it’s value spending all that more money on one thing you’re in all probability solely going to make use of for a couple of hours a 12 months. There aren’t emissions checks or upkeep checks like there are on different forms of engines or extra everlasting mills, so (for now) I consider you’re completely okay getting whichever generator works greatest.
How one can join your motorhome generator
This bit is fairly simple. The toughest bit is ensuring you could have purchased the proper adapter to hyperlink from the generator to your motorhome. The gen-set might use a motorhome energy lead (by which case, you possibly can normally use the identical one you do for mains energy), or it’s a 3-pin plug (so you must purchase a lead like this).
How one can use a motorhome generator (step-by-step)
- Take the generator outdoors
- Do any upkeep which wants doing (together with including gasoline if obligatory)
- Begin the generator
- Let it heat up for a couple of minutes with out load (ie- with out it being plugged in)
- Plug in ( plug into the motorhome first, then into the generator)
- Activate home equipment separately, so it’s a gradual build-up as an alternative of a pointy shock
- Monitor for some time to verify all the things is okay, then use
- Take away energy lead BEFORE you flip off
- Flip off (you are able to do this shortly)
- Depart to chill down
- Drain if required
- Retailer away
How lengthy can a motorhome generator run?
Okay, don’t get confused between the large RV mills (which can be utilized whereas the RV is operating and even being pushed in some circumstances), and a UK/ European motorhome/ campervan transportable generator. Our model is supposed for use as an occasional use backup, not run for 8-14 hours continuous!
After all, each generator is totally different, and lots of may be run for as a lot as 6 hours, however I’ve by no means ran the generator longer than a few hours. I by no means wanted to; as soon as all the things was totally charged and I’ve used what I’ve wanted to, I turned it off.
Hold a log of the hours run
I extremely advocate retaining a operating tally of the variety of hours you utilize the generator for. You would put a little bit of paper inside your motorhome guide, and even higher make a remark of it in your motorhome logbook.

Motorhome Generator upkeep
It is very important preserve your generator, in order that it’s obtainable so that you can use if you want it.
Make sure to give it a visible inspection each time you get it out and pay attention for any adjustments in velocity or noise- that might detect a difficulty which wants fixing. You’ll hear a distinction within the engine noise as you turn home equipment on and off (because the load calls for change) but additionally pay attention for something outdoors this.
Different yearly/ common upkeep checks would possibly embrace:
- Gasoline filters- change each 2 years or 400-500 hours (verify producers handbook)
- Engine oil, filters, air cleaner (if used)
- Oil ranges
- Valves, slip rings and brushes
- Exhaust system
- Drain water from gasoline system (diesel generator)
- Examine gasoline provide strains and different rubber hoses
Like most engines, mills usually are not nice in the event that they’re not used typically. Make sure to preserve, clear and run them repeatedly, even for those who don’t want them proper then.
