The yachts that have big generators have electric
compressors. Most cruising boats do not have a big enough generator
Our 30 year old generator died recently has just been replaced. We explored the idea of going to electric
compressor. Spent some time learning
about the issues. The big problem with an electric compressor is the startup surge. We talked to a number of installers that said they would NOT be responsible for any of the motor
startup problems. The huge startup power requirement is often more than the generator can provide.
I talked with a few of the compressor vendors for Bauer and was told that they could not be responsible for the startup problem and that the generator installer needs to be responsible. I ended up talking with the expert at Bauer to get some numbers for startup and then confirmed with the Northern Lights
dealer to determine the size of the generator. Just had the new 6k Generator installed. Old 5k generator that lasted 25+ years was starting to fail and needed to be replaced. Dealer price
is 13 k not installed
Have not yet traded in my Gas compressor for electric yet. I plan to buy the electric one.
NOTE - I already had a Bauer Junior gasoline powered and planned to just change the motor
There are a number of compressors that come with some form of "Soft Start" that lets smaller generators run compressors.
I'm still not sure I want to go to electric. The gas one has been easy to maintain. And it is very portable if we want to take it out on another boat
or for diving off the beach
