The Rutland 913 commercial generator
My experience with this highly acclaimed commercial wind generator was disappointing.
The company Marlec engineering produce this generator in Northhants, in the UK.
It sells for £399, I managed to get one for £250 second-hand.
The company provides the following data on the Rutland 913.
Generates 90w @ 19 knots, 24w @ 10 knots
Delivers up to 250w
Low wind speed start up of just 5 knots
One way only fit fine profile efficient aerofoil blades
Three phase Rutland "unique" generator design
Automatic thermostat protection in prolonged gales
Because I live inland, in a reasonably built up area, the 913 never reached it's true potential - it would spin freely in a light wind, but only
reach 12 volts at a rapid rpm - when a load (a 20W bulb) was connected the generator would slow and ultimately stop.
Considering the cost new, it didn't impress me. Although in the right location, e.g coastline, I'm sure it would perform well.
The build quality was very good, and worth considering buying if used in the right location.
I sold mine on eBay for what I paid for it. Thankfully.
