Re: generator a good idea?

Dave,

Before anyone can give you an intelligent answer, you need to figure out your typical power consumption per day, your house bank battery capacity, and how long you plan to stay at anchor without running the engine to charge.

For example, if you use 100 Amp-Hours per day and only stay at anchor for one day at a time and have a 300AH battery bank, you'll be just fine as it is because you won't drop below 50% state of charge. If you're willing to run the engine an hour or two per day to charge and have a high output alternator, you can go indefinitely at 100 AH consumption per day. If you don't want to run the engine or use more per day or have a smaller battery bank or stay on the hook longer, you'll need some charging source but how big and what type depend on other considerations.

The Honda EU2000 will put out 13 amps for as long as you keep it gassed up but that's a lot of noise for a long time. A few hundred watts of solar can supply a similar amount of current and do it silently but won't help you much if you sail in the winter in the PNW.

etc, etc.
