    Smile Best generator for a mobile coffee trailer? What are you using and is it any good?

    Hey!

    I'm shopping around for a generator for my coffee trailer. I'm learning as I go when it comes to Watts and amps etc. Got another thread here that quickly taught me to rely on my electrician for that kind of thing!

    But I am really interested to know what kinds of generators other mobile coffee trailer owners are using. I've been recommended to buy a Honda EU70is. It is massive, very heavy, the quietest generator on the market, and quite expensive at around $6,000.

    Is that what other people are using? If not, what alternatives can you suggest?

    I will be powering up a 2 group (compact commercial) La Pavoni coffee machine, a La Pavoni Commercial grinder, a display fridge, a surplus fridge, lights and radio. If everything got switched on at once, it would power up to just over 5000 watts.

    Those recommended generators (your other thread) "Electricians have been telling me I need to get either a Honda7000 or Yamaha6300 generator (Honda weighs 118kg and Yamaha weighs 91kg). Both appear to cost about $6K (which is okay if they are good and reasonably quiet). The weight of the generators means I will need to get a new A-frame because my imported tow bar is unlikely to pass vehicle inspection (storing generators on A-frame)." sound about right. I have an old (1990ish) Honda 6.9Kw one which would be fine in terms of grunt - however it is a seriously noisy S.O.B.... I strongly suggest you do some noise tests personally.

    Also, FWIW, I reckon your max draw is possibly / probably way off, as most fridges usually require a lot more power on start up. Once the whole lot is going, continuing operation should be fine. I also have a two group "full size commercial" 1980's two group La Pavoni (P/TRE model). It is supposed to pull 3600 watts on start up - it is actually closer to 4,500 on my (calibrated) multimeter. I then crosschecked it by blowing a 16 amp then an 18 amp circuit breaker repeatedly, nope - it wants a full 20 amps. That machine takes around 40 minutes to reach stable temp. After that, it runs on very little (the rotary pump is 450 watt if memory serves correctly) until the elements fire up again. That machine has pulled over 100 shots per hour without breathing heavily, so I expect your predicted workload would be easily accommodated.

    Rather than getting a compact model which has smaller boilers, I would suggest you get the full size one as the larger boilers would work in your favour "on the road". Then I would see if your can arrange to have a switch to turn one of the elements on an and off. That would bring your "boiler power load" down to the 2000 watt mark. That combined with firing the whole thing up at your home on a 20amp circuit for an hour "before take off" would make the power feeding issue a lot more manageable. Oh, and please get the shortest "real 20 amp" extension cord you can to prevent house fires - my dad was a safety engineer and I have seen some shockers (pun not intended but hey, it also works).

    Solar panels: to do them properly you would have to add a serious chunk of battery storage and a large inverter. Even using Lithium Ion batteries that may be prohibitive due to weight and cost. Of course, on the plus side, you could run the grinder and the fridges on the solar and split the loading that way.

    Good luck with your endeavours - at least you are doing your research before you commit to the wrong gear.

    A few months ago there were workmen outside my shop cleaning the pavement using Honda EU65is generators, they are the predecessor to the EU70is I believe. They were extremely quiet but quite large as you would expect.

    From a noise perspective, it would certainly be ok in a public space. Consider placing the generator behind the van in a partial enclosure (ensuring airflow in and out) and you shouldn't have a problem.

    They are still for sale new as far as I can see from a few suppliers and are a little cheaper than the EU70is. The 6500W max power output may be too little, I would advise getting an accurate figure for your max power consumption first.

    Hey mate just curious as to what you went with, is it petrol or diesel? Mounted at front of trailer is it quiet enough? Any fumes?
