a Kiss which is getting a bit long in the tooth. It sill works but the blades are starting to show signs of sun and it's starting to be the last in the anchorage to start to turn when the wind comes up. It's been a good unit and puts out a reasonable amount of power with 18 to 20 knots but we are in Mexico on the pacific side and generally we don't have that much. I'm thinking of replacing it with a unit that puts out less amps at a lower wind speed. Over the course of a day the total amp output would be more then what I'm getting now. If I could get three or 4 amps an hour all day long, that would cover almost all of my requirements. I don't need 20 amps output. I'd be happy with two or three amps.
