    We have just changed our MH to an Adria Vision i707SG. Very happy with it so far (although that is only on the drive!).

    It has better storage than our last one so we were hoping to get a small tassimo coffee machine (I love my one at home). We would only be using this on EHU.

    It says its output is 1300W. Will we need an inverter? if so, what size and type as I have no clue about these things.

    Thanks in advance

    If you are using hookup, you will have 240v to use the coffee machine, you will only require an inverter if you are not on hook up.

    Thanks. For the odd occasions we are not on hookup I can slum it with the kettle then!

    You don't need an inverter, you are much better of with a petrol genset...

    1300w is a massive load on your battery's (about 100A at 12V) all the time its switched on.
    A 240v telly/fridge takes about 8A.
    Although I do love inverters I would not recommend any appliance with an heating element to be run by an inverter unless you have huge battery's.
    Save it for when you are on EHU

    I did actually say we would only be using it on EHU in my original post!

    The big load is only there when the machine is heating up which is only seconds, 200ah of decent batteries is OK and a bit of solar puts it back.

    And that was the question - I didn't know if I needed an inverter if on EHU or not!

    To be fair I did say I didn't have a clue! @Jonned ticked all the boxes with his response!

    Just in case anybody reading this is confused, an inverter makes 240 volts AC from your 12 volts DC battery, to do this it uses a lot of amps from you battery typically about 20 times the amps that the equipment needs when plugged into 240 volts, so a 1300 watt coffee machine needs about 6 amps so that's about 120 amps from your 12 volt battery, if you have a useable capacity of 100 ah (200 ah of battery bank as you should not go down lower than 50%) then you could not run the coffee machine for an hour, but the important bit is that you would not need to as it takes only seconds to use a Nespresso or Tassimo machine so only a little bit out of you batteries typically 2 minutes would take 6 ah which is nothing.

    Sorry if this is common knowledge to everybody reading this, but just thought it might help somebody.

    Not quite true...

    Battery discharge was discussed on another thread recently, and the discharge rate is significantly higher at higher currents, have a look at the chart I linked to here:-

    www.motorhomefun.co.uk/forum/threads/do-you-know-how-many-amps-you-use-each-day.117630/page-3#post-1590493

    At those sort of loads you would be looking at about fifteen to eighteen minutes to drain healthy and fully charged batteries below fifty percent.

    Agreed that a few seconds is do-able, but, forewarned is forearmed, and Iwhilst do let the mem-sahib use a 1000w hairdrier for short blasts, I wouldn't want anything that runs for more than a minute or two running off my leisure batteries at that draw.

    But the Golden Rule of FUN is to read only one line. You put that vital bit on line 4.

    I can write anything here and it is completely invisible to the myopic FUNsters with the attention span of a tired geriatric goldfish. And take all technical answers with a pinch of salt, there are people on FUN who write 20A when really they should be writing 19.8724A, they just don't care.

    I find this is easily the best way to make good coffee, both at home and in the van. I'm not one for 'frothy' stuff, though. So if you like the ones with a frothy head, you may need a machine.

    We take our Tassimo with us and use it when on EHU, no inverter required. I use a cafetier, with Costa coffee, when not on EHU.
