Really? In a steady 20 knots, my Air Breeze will produce about 175 watts. Since I only have a 420 AH house bank, it's rare for the wind generator to run long in that sort of wind before shutting itself down.

Maybe check and see what your wind turbine produces (in watts) when the battery is below 12 volts with no load on the battery (so you know it is truly almost completely depleted) and the wind is blowing pretty good. That should be a situation where it is producing a maximum charge. If it does not produce a full charge then you know with certainty that there is a problem.

Re: How Much Real Energy Does Your Wind Turbine Put Out?

We have an Air X 403 connected to our house batteries (HOUSE, not boat) which consists of 1320 aH of golf cart batteries.
I routinely see 400 watts output in 30 knot winds when the grid goes down.
We run the whole house off this system.
It consists of an 1800 watt sine wave inverter (regretfully a Xantrex I repaired before I knew better) minus 220 volt loads.

As far as the boat?
Strictly solar with LiFePo4 batteries, LED lighting and Aerogel insulation in the fridge and hot water tank.
See the thread on "LiFePo4 batteries for house bank", and various Aerogel for refrigeration threads.

I learned a lot.
Now with 320 watts of solar, we have ONLY ONE 200 aH battery bank and never need to run the engine for power !!!
Thanks CF !
