    Hi All,

    I have a family that has a Wally Tender X model.

    They are BIG coffee lovers and want a Nespresso Inissia to be installed in the boat which will be able to give at least 6 cups of coffee per hour and when they go out, they spend at least 5 hours out which means I need to be able to get the machine to be able to function in order to produce this amount.

    The machine is 220V, 50/60Hz, 1260 W in their specs.

    Can anyone please advice me on what type of battery, specs, inverters if needed, cables for the power to flow through, etc. What do I need to get this machine to work for those hours. I can recharge the batteries when we get back into port.

    You ll need a 2000w pure sine inverter. I mnnot familiar with the Inissia but I have Virtuolines on both my personal boat and the boat I run and they don’t use much power since they don’t run for long.

    If the house bank is big enough it should be able to handle it especially if some of the time is spent underway.

    For a 2000W inverter 2/0 size battery cables should be fine for short distance. In any case it will be listed in the installation manual

    Hi Pascal! Thanks for the notes. The current batteries can't take it. It gives 5 cups and is out flat.

    So we were thinking of doing a separate system just for the coffee machine. It would be lithium battery + Inverter + cables (strong enough to carry the power). What I can't figure out is the power requirement for each item, how much power I need in the battery, inverter and the cables.

    If you know anyone which can give me the correct breakdown it would be appreciated.

    search the net for "12v coffee machine nespresso compatible".
    you'll find few machines for yue need.

    Thanks Menkes! We tried several portable espresso makers. However, due to the amount the family needed per day, after a week of heavy use most of the time they become unstable (on/off). We saw a boat in Sardinia, which was a coffee and ice-cream selling boat (they would move around key areas in Sardinia selling coffee and ice cream. It had a proper big coffee machine so I know the set up can be done, but I just don't know how it was accomplished.

    Once you are used to Nespresso you can’t go back to stovetop... plus I doubt his boat has propane stove.

    1260W is about 6amps at 220v. Even if it runs a quarter of the time it would be about 2 amp hours or roughly 20AH at 12v.

    5 hours on the hook will require around 100AH. You ll need at least a 200AH battery bank avoid discharging below 50%. A single 8D should do or two 6v gold cart batteries

    Again as I said before a 2000W inverter should work and 2/0 to 4/0 battery cables depending on how close the inverter will be to the battery bank. Ideally no more than 6 to 8’. You need a short distance between battery and inverter, although distance between inverter and loads on the AC side doesn’t matter

    Someone check my math as I am not properly cafeinated yet :)

    We have an Inisia at home, it s a small one should be easy to set up

    Btw and please don’t be offended but considering how basic your question is I would strongly suggest you get this done by a marine electrician

    No worries, I definitely intend to. But as they seem to find this request odd, they may need a little guideline. Im having it done in Europe as the boat is there but it seems either the guys aren't very helpful or they haven't done something like this before.

    thanks a lot for the help Pascal! if anything else crosses your mind please do let me know.!

    You didn't say how long you want the battery to recharge in, but I would recommend a 20 amp battery charger. Another route you could take is a 24v inverter system using 2-group 31 batteries, then your cable sizes are smaller, the system is more efficient, and the batteries are easier to find a location for. How far is it from the batteries to the inverter location?

    Actually most marine inverters double up as charger and a 2000w inverter should charge at about 40 or 50amp rate. Must faster than most stand alone chargers. From what I recall the 4000W Magnum inverter i used charged at about 100amp rate.

    A lot of the smaller ones don't charge the batteries.

    Also, I've come across a lot of larger inverters that if battery voltage gets to 21 volts on a 24 volt system. Or 10 volts on a 12 volt system, they won't even power on in order to charge the batteries. But on a small boat like that, you could always put a portable charger on the boat, to trick the inverter/charger into powering on.

    Plus 1 on the 2kW pure sine wave inverter. The OP has not told us how long the appliance runs to brew a coffee - this is important to the solution, and I don't know the answer. 1260 watts is 105 amps at 12 VDC, if you figure 95% efficiency in the inverter, 110 amps, realistically. If you figure 5 minutes per brew, 6 brews per hour for 5 hours (at least) that's 30 minutes x 5 hours or 2.5 hours at 110 amps or 275 amp hours at 12 VDC. That would require a 550 AH bank to stay above 50% discharge. Resistance heat appliances are a bear to run on batteries, aren't they.

    Don't forget that because this is during the day one has to assume a certain amount of time the mains are running so the alternator will pick up the slack.
