Efficient power generation for the dark days of winter

Published / by bde / Leave a Comment

Most everyone living offgrid relies on some sort of generator as a mission critical power generating device. I’ve purchased 2 generators and am using neither of them.

The 5500 watt Generac is a propane powered unit with several glaring design flaws. It’s damn near impossible to start in cold or warm weather and sucks down propane. It has less than 60 hours on it. I’ll sell it for half what I paid or best offer at this point.

The Honda EU2000 gas powered generator worked fine all summer but then stopped putting out AC power. I’ve done a fair amount of troubleshooting and think it’s the inverter board. I’m certain excessive moondust is to blame.

So here I am getting by perfectly with the custom 6.5 hp/212cc motor/alternator setup. Still blows me away every time I fire it up.

This is all I need to charge my batteries and power everything needed in the cabin. 3/4 gallon gas lasts 10-11 hours and will leave batteries fully topped off even during times of heavy use. That’s pretty damn impressive.

This includes my well pump and all 110v AC and DC appliances. Oh also — It only cost about $300 for all the parts. Compared to $800 for the General and $800 for the Honda.

Have a a smaller 3hp engine on order that a buddy is gonna setup. See if we can fine tune and run even more efficiently.
