 Chinese 300W wind turbines (12 and 24 volt) |
|||||||||||||
| EcoInnovation has been testing two of these turbines for the last 3 and a half years on our own site, and has installed over a hundred of our modified version in the field. Our initial impression of the turbine was low, the problems were as follows: · Ripples in blades on one model · Blades were out of balance and the turbine vibrated severely · Sharp burs on components · Wires were likely to chaff on sharp unprotected holes · No slip rings · Very poor electrical components · The tower supplied with the turbine is unsafe and should not be used To rectify these issues EcoInnovation makes a number of changes that included: · Vast improvement in blade retention · Addition of slip rings · 3phase rectification at the turbine and dc down the tower · Balanced blades · Addition of grease nipple in the tail pivot · Addition of good quality voltage regulator and diversion load |
