- - One of the forgotten aspects of wind
generators is the power regulation. With liquid lead acid batteries the is only minor consequences of over-voltages. But with Gel-Cells and especially AGM
technology batteries, overvoltage can cause serious damage and significantly reduce the life of these batteries.
- - With low output wind "turbines" (I differentiate between the two styles - 3 or less blades are wind generators and 6 blades or more are wind turbines) - the outputs are low and can do less harm to the batteries - but they take much longer to charge a battery
bank. With high output wind generators getting into the 20 to 40 amps and 16 to 17 volts (unregulated) you can fry your batteries.
- - So some sort of voltage regulation is necessary. Either by external diversion regulators or internal (inside the wind generator) regulators. All the Air-Marine incarnations have internal regulation. The prices of a good diversion regulator
can be significant and then you have to provide a place for the diverted power to go.
