Parallel Yamaha EF2000 or Single EF/EU 3000

I already have a single Yamaha EF2000, but need something with more power. I am looking for something to use as a backup to my Westerbeke 12k genset on my houseboat - mainly to run a fridge, chest freezer, power the inverter and charge the batteries on the houseboat. I know that running the smaller generator to charage the batteries (6 of them) will be much more fuel efficient than running the Westerbeke, which is my main concern.

Looking for opinions on what would be a better option. Getting a parallel kit and a 2nd EF2000 or selling it and buying either a Yamaha EF3000/Honda EU3000.

If I go parallel I will need a 2nd generator, parallel kit, extended run fuel tank (do they offer one for a Yamaha?). I see the advantages of going this route as more power available, easier for me to handle two smaller generators than one bigger one.

Single 3000 advantages would be lower cost (?), only one generator to maintain.

Am I missing anything?

  • I like having two 2000 Honda generators with the parallel kit. It provides flexibility. If we plan to run the A/C I carry both. If no A/C I carry one.

    At home or helping friends with projects I use one or both depending on how much power will be needed.

    The two hondas while powering the A/C and other stuff go through a tank of gas in around 4 hours so I just refill and don't use an extended run tank.
  • Hi,

    I'd go for the Yamaha iSEB 3000. Smaller foot print than two generators and 1/2 the maintenance. 20.5 hours run time at 1/4 load, and 8 hours running "flat out". Factory remote start is available. It will power a 100 amp charger.

    You may wish to consider adding some solar to the "mix".
  • It seem like if a 3K would do the job for you then it would be a lot less hassle than dealing with two gens and the extra cabling.
