Re: [Electric Boats] Re: Inverter Duty versus Standard Duty Generators

 

Hey Eric,

Your post is either uninformed or sided.  There are inverter generators sold by other manufacturers than Honda.  All Inverter generators I know of work on the same principal. All are quiet when compared to standard gensets.  Kipor,Champion, Honeywell, and other china produced products are on the market that are inverter units and quiet.  Fact that many of the parts for Honda are sourced from China opens question to quality.  The Champion unit sold by Sam's club has a better price.  The Honeywell unit supported by Honeywell and is sold by Costco.  Both units are sold at a considerable savings to the Honda unit of same size, and all of these are inverter quiet generators.

I will gladly say that I prefer keeping my money in the US, but hey Honda is not US produced. Most parts these days are made in China so where do I turn.

On another note. How do we justify running a 120vac generator in our boats when we have not considered installing our conversions not to the above 50vdc standards set by industry organizations. I have done it but really, are we trying to install our upgrades to standards or not?

I've know a couple RV people that have owned some of the cheaper 2kW generators. Some have not been particularly reliable and all have been noisier than the Honda or Yamaha i-series. Everyone of the RV owners that I know have replaced their "off-brand" generators with one of the i-series for either noise or reliability.

The cool thing that the inverter generators do is adjust the throttle of the engine to match the load. Most non-inverter generators run at one setting, wide open, regardless of how much electricity is being used. This makes a big difference when you're running lights or other random loads for backyard or on-shore parties.

For my boat, I want to get as much power as possible into my batteries to minimize the time on the generator. So if your charger input is sized to the continuous generator output, the inverter feature will not have much effect, the generator will be running flat out just to cover the load. If your charger is less than capacity for the generator (like a 15A 48V charger, about 1000W input) then the inverter generator will be noticably quieter because it will throttle down to match the load. Even more so for a 10A 48V charger.

So it all depends on your specific set-up. But for me, the reliability of the product makes the brand name inverter generator a best buy.

Fair winds,
