Keurig on the boat - Coffee anyone!

[Capt’n Ron]

As boaters we learn from the time we purchase the boat to every time we step on the boat.

My coffee story:
When I purchased my 795 I told the sales person at Sundance I wanted to use my Keurig on the boat, so he ordered up an inverter/Charger to be installed. Problem was every time I tried to use the Keurig it shut the inverter down. They did a fair amount of trouble shooting and kept adding house batteries (4 in total), but nothing seem to work. So I dug in and did my research and found I needed a pure sin wave inverter to run appliances like coffee boilers. As it turned out the dealer had installed a modified sin inverter (Xantrex HS 1800) which is not designed to handle loads such as motors and boilers. I had brought that to the attention of the dealer multiple times over the last couple of years, but they did nothing to resolve it. Lately I had been having issues with my battery bank losing charge too quickly so I decided it was time to take things into my own hands and replace the inverter myself with a Xantrex HFS 2055. The job was pretty straight forwarded except I found the dealer never did run a ground to the inverter so I’ve been running for 3 years with a fire hazard.

With the new inverter installed (and grounded!), I can now use my Keurig on the boat to satisfy those early fishing mornings with a fresh cup of brew!

A couple technical notes: When it runs the pre-brew it draws about 1500 watts and the voltage meter drops to about 11.8V and then pops back up to normal voltage when the boiler is done. After three cups I used about 11 amp hours (or 3Ah per cup). So plenty left on my 200 usable Ah on my battery bank. One thing to note, I had to set the battery shutdown threshold on the inverter to 10.5V instead of the middle setting of 11.8, otherwise the inverter would have shut down so be sure to keep an eye on your battery voltage meter.

Happy brewing!

My first coffee on board the previous Jeanneau was similar to your story and it was an expensive brew indeed. I wanted a Nespresso machine. First off, the inverter couldn't handle the load, so I got a bigger inverter. Then the batteries turned out to be too weak so I added to the bank. Then I realized that the cables to/from/inside the battery bank were too small and had to replace them all. But that first cappuccino tasted delicious!

In my case the Nespresso machine never peaks too high on the consumption side, it warms up for a minute or two at about 800W and then make the espresso with 1500W for 20-30 seconds. I dreamed of putting in a combination machine that grinds, tamps, brews and ejects the grounds but that would take up too much valuable counter-space.

This was my solution to making a great coffee onboard. It makes the espresso and froths the milk.

We have some rules about how to operate it, like not leaving it unattended.

That's pretty cool!

I use my Jura Ena Uno
Everyday on the boat with my 3000w(5000 pick) pure sane invertor with remote

The invertor cost is £370 and works luke charm for the coffee machine, fully automated washing machine, aircon and hot water boiler and everything else that I need on 220v - my boat is Sun Liberty 34 /1990 in currently crossing the Corinth Channel
