You might have seen that the Yamaha EF2400iS recently came out on top in the Caravan & Motorhome Magazine’s Mega Portable Generator Comparison of 2014.
Clean power: Thanks to the inverter technology, both generators will safely power sensitive electrical devices, such as laptop computers, without power surges.
Quiet Please: Yamaha Generators are known for their quiet running, which is one of those things that makes the so attractive to the leisure and recreation market.
Fuel Efficiency: When it came to the fuel efficiency test, the Yamaha 2400 watt was the generator in the comparison that lasted the longest under the same load on one tank of fuel. Once you have these numbers for your appliances, you can work out what size generator will work for you. Regarding the comparison of the two generator units, the Yamaha EF2400iS is slightly lighter, quieter and over $1,000 cheaper than the Honda EU30i Handy, but obviously the Yamaha produces slightly less power…so again, it all comes down to the wattage requirements of your particular appliances. Hi Glen, we always advise that you find out what the peak power surge at start-up (in watts) that your particular Caravan Air-Con model will require.
In terms of the Yamaha EF2400iS, from our testing and experience, it will run mostly all Caravan Air-Con models from the major brands on the market, noting that there are a couple of specific Caravan Air-Con models at the larger end that will test it, or even be too much for generators of this size, especially in hotter conditions. In summary, most people requiring a generator to run their Caravan Air-Con will opt for a Yamaha EF2400iS – it is a quiet, reliable and fuel efficient machine that will comfortably run the vast majority of Caravan Air-Con units on the market. 1) They have an especially large Caravan Air-Con unit that needs more power so they need a larger generator (or in some less common cases the opposite is true, whereby they have a smaller Air-Con unit and can get away with a 2000w generator). 2) Many people will just want to run their Caravan Air-Con from the generator and that’s it. Lastly, its worth noting that in hotter environments, any generator’s power capacity will slightly reduce. I believe they are very similar and commonly have the same performance.It will depend on which of the two products is more effective and usable in terms of longer life. As a complete newbie looking to set up a motorhome for protracted off grid existence, I wanted to know whether the 240 volt requirements can be supplemented by the vehicle’s engine power output? Hi Bill – the article is referring to air-conditioners for recreational vehicles that require 240 volt power from either mains power or a generator.

Roof Cargo Basket Im in the market for a roof basket, I have been in contact with Norcal, and im getting info etc from them, just wondering if anyone else knows much about them.
So I may have to mod a basket, or mount it reverse (some have tapered fronts for areodynamics.
Well cab lights reflect off the hood at night so I'd think you might get some from a light bar. That's not a bad idea really, maybe you could attach it to the rack itself somehow and then mount the light. It has become increasingly common to provide heat recovery on ventilation systems in buildings.
The technologies are mature, with a variety of products available including plate heat exchangers, sensible and enthalpy wheels, heat pipes and runaround coils, all intended to pre-condition incoming ventilation air by using the energy in the building exhaust air.
This article surveys the established ventilation heat recovery systems and the less common ground heat exchangers, drain water heat exchangers and equipment heat recovery systems. In the 1980s, Canadian companies pioneered the development of packaged heat recovery ventilation [HRV] systems which became a cornerstone for R2000 and similar energy efficient houses. Innovative manufacturers assembled a neat, ready-to-install package consisting of an efficient plate heat exchanger core, balanced supply and exhaust fans, a defrost system and simple remote controls. The early HRVs used plate heat exchangers, which were very effective in removing excess moisture from houses in winter, even too effective. Heat exchanger cores were also built into wheels that rotated between the exhaust and fresh air stream, using materials that were either permeable to moisture or were coated with a desiccant that successively absorbed then released moisture.
While the small HRVs and ERVs in the 100 – 200 cfm range found a place in the energy efficient houses across Canada and the US, large models with 300 – 500 cfm capacity were soon developed for use in light commercial and small industrial applications that would benefit from continuous ventilation – swimming pools, health clubs, vet clinics, offices, workshops, garages, etc. Now, several manufactures offer packaged HRVs and ERVs in capacities above 1000 cfm designed for larger buildings. The heat recovery technology goes beyond cross-flow plate and rotary wheel heat exchangers, however.
When it is not possible to arrange the main exhaust duct beside the building fresh air duct, glycol runaround coils have often been installed to transfer heat between the two airstreams. One manufacturer offers a reversing flow HRV in which exhaust and supply air are alternately routed through two thermal storage cassettes. Standards writing organizations for the HVAC industry – CSA and ARI – have published standards for the design and performance of HRVs and ERVs and offer a reliable third party basis of evaluating most manufactured products.
Heat can be recovered from the ground to help heat buildings, using either a greater or lesser amount of energy to retrieve it.
Originally pioneered in Europe to reduce the air conditioning energy, ventilation tunnels serve as the main air inlet for the building ventilation system.
The tunnels are made of precast concrete sewer pipe and run 2-3 m below grade from the air inlet structure to the building foundation wall and air intake plenum.


Alternatively or additionally, the building foundation can be constructed with an inner wall to form a perimeter corridor serving as a fresh air plenum.
The ground can also be used to store solar heat that is abundant in the summer, to be extracted months later when needed for winter space heating. When we take a shower, we send a lot of hot water down the drain that could be used for heating the cold water going to that very same shower water.
Many buildings, particularly in remote sites far from the utility grid, generate their own electricity with on-site generators.
The key to developing a more efficient electrical generation system on a community wide basis is to build electrical generators that are small enough to be able to efficiently distribute and use the heat within a short distance of the generator.
This inverter generator boasts 2000W continuous output and 2400W peak output, which is pretty much all you’ll need for most caravanning tasks, particularly if you intend to run an air-conditioning unit. Unlike the Honda 2000 watt, the Yamaha has a fuel gauge so you can easily check the fuel and see when it’s running low. But it’s important to remember that with the Yamaha, you’re getting more power in the package.
Both the Yamaha EF2400iS and Honda EU20i have a super quiet 54 dBA at seven metres distance. The Yamaha EF2400iS gives you significantly more power but you sacrifice some of the portability that the Honda EU20i offers.
We only camp in non-powered sites so this feedback information back from you is critical and more than likely applicable to others for our same or similar requirements. Our Generator Buyer’s Guide provides a step by step example regarding generator sizing which may also help. Note that some older Air-Con models are not very efficient and can draw quite a bit of power. Again, these types of cases are not as common, but its always best to find the peak power surge draw of your specific Air-Con model.
However, some people will have a number of other Caravan appliances they want to run at the same time as their Air-Con, e.g.
Also, the longer the extension leads, the more the generator’s capacity will slightly reduce too. Ideally you would know the starting and running wattage for your particular air conditioner model to be sure you are choosing the most appropriate sized generator.

It also covers our content moderation policy and what you can expect regarding performance and availability. Big crates, or reels etc can go on deck, but small boxes, etc will end up all over, or in cab etc.
However id prefer not to bolt through the roof (thats just asking for leaks over time etc), also the sled deck is going to have a headache rack, and I do haul stuff that will extend up over the headache rack and be tied down to it. Ill try and get into some decent cell service during the week and call, email seems to be a pain sometimes. The energy recovery in winter and summer is sufficient to temper the air about 5? C on average and up to 10? C on cold days.
In fact, it is difficult to achieve the minimum energy performance requirements for a LEED or other high performance building without it. The recovered heat is used to heat the building ventilation air, water for hydronic heating or water for domestic hot water. Building scientists had shown that houses, and other buildings, needed adequate ventilation for healthy indoor air quality. Builders then only had to connect it to exhaust grilles in washrooms, kitchen and laundry rooms, and supply diffusers in bedrooms and living rooms, and then run two ducts to outside wall hoods. This process recovered more of the energy of the exhaust air and so energy or enthalpy recovery ventilators [ERVs] became available offering total heat recovery efficiency and winter time humidification. When properly designed and installed, the HRVs and ERVs could dramatically improve the problems these buildings had with high humidity, odours, fumes and smoke.
Heat pipe exchangers are built with pipe loops containing refrigerant and extending into the exhaust and fresh air ducts. A dedicated pump and piping system circulate a glycol solution between coils in each of the two main ducts.
For a short interval, a damper routes air one way through the cassette heat exchange media; then the damper repositions and redirects the air through the opposite cassettes. Ground source heat pumps rely on electrically powered refrigeration compressors to pump heat from the relatively low temperature shallow ground.
In the cooling season, ventilation air is pre-cooled a few degrees from outdoor temperature before entering the main air handling units. Air is admitted to the plenum at one end of the foundation and extracted by the air handlers at the other. A gas or diesel engine generator is not very efficient at producing electricity – only about 35% of the fuel usually ends up as electricity.


Currently, electrical generators operated by the electrical utilities are too big – they generate too much heat to be used economically within the neighbourhood. In fact, we know that many people compare the Yamaha EF2400iS against the Honda EU20i when they’re weighing up portable inverter generators for their caravan. However, this might not be clear when you look at the specifications because the Honda EU20i actually has a 10-hour run time.
We say; if you are looking at running your caravan air conditioning unit and associated appliances, the Yamaha is your best bet. I would strongly suggest you give your Air-Con manufacturer a call and ask them for the starting wattage of your particular unit – we find the technical support staff for most Caravan Air-Con brands to be very helpful. Often the best way to do this is to contact the Air-Con manufacturer, speak to their technical department and ask what size generator they advise will run your model of Air-Con.
Just be weary of these additional influences on the power performance of a generator – so if you are going to be in particularly hot environments (above 30 degrees Celsius), or run long extension leads (longer than 4 metres) then factor in some additional power contingency when doing your generator sizing calculations. We find the best way to get this wattage information is to contact the manufacturer (in your case; Air Command).
Could having the vehicle running when powering on the aircon (or other high draw component) cover any lack of power from a generator? In terms of your vehicle, it would depend on your particular battery system set up – it might pay to speak to a RV air-conditioner installer.

Recovering heat from building exhaust air to pre-warm the fresh incoming air significantly reduced the energy cost of this ventilation. The result was a simple system that controlled humidity, odours and other indoor air contaminants, and which did not de-pressurize the building or cost much to run.
The idea of delivering continuous exhaust and an equal amount of conditioned makeup air was not new; what was new was the ability to do this with off-the-shelf equipment in one package. Large capacity units can also be supplied as add-on upgrades to other roof-top equipment, although there can be complications when trying to interface and optimize the equipment from two different manufacturers. The heat in the exhaust air is transferred to the fresh air by the action of the refrigerant evaporating and condensing at each end of the pipes.
Heat recovery efficiency is less than other technologies and is generally limited by thermodynamics and coil capacity to about 45%. They can recover about two to four units of energy from the ground with about one unit of electricity. The un insulated outer wall serves as a heat transfer surface between the ground and the incoming ventilation air. Manufacturers estimate that the heat exchanger can reduce water heating energy by 25 to 80%. Here, it’s important to remember that the runtimes on the table are looking at how long the generator will last on a quarter load. Lastly, it also pays to be weary of unintentionally drawing power to charge your battery system at the same time as running your caravan air-con for example – sometimes trying to draw power for both sources at the same time will be too much for some generator models. Similarly, you will need to find the starting wattage of your microwave – again, its that starting wattage which is the most important number. We often get calls from customers saying that their 2000w generator won’t run their Air-Con when it’s hot or when an extra extension lead is attached.
I want one but the $700+ quote he gave me was just too much for me since I won't use it like you or others would.
That was over 25 years ago – the rest is a history of continuous innovation in products and application. Heat pipes offer the benefit of a more compact installation for large airflow systems and simple defrost control.
However, with much less energy input, ventilation tunnels and double foundation walls can also recover usable heat to precondition ventilation air.
The Earth Rangers Centre [earthrangers.ca] near Toronto uses tunnels [earth tubes] and a double foundation wall. The heat exchanger is a central section of copper drain pipe, surrounded by a spiral of copper water pipe.
So if your building is in a cold climate, like Canada, most of the annual energy requirement is for heating, and much of that heat can be captured from the engine coolant and from the engine exhaust using special heat exchangers designed for cogeneration [equals combined heat and power].
The Yamaha EF2400iS might be ok to run your Air-Con plus some other appliances at the same time, or it might not – it obviously depends on how much power the sum of all your particular pieces of equipment will draw.
When both electricity and heat are utilized, the overall efficiency of the system can reach 75%. Also keep in mind that if you want to run other appliances at the same time (or simultaneously charge your battery system) then this extra power needs to be taken into consideration when sizing your generator also.
