500 Watt Grid Tie Inverter Wind Turbine Kit

We have perfectly matched our Missouri Wind Turbine to the 500 Watt grid tie inverter for next to a plug-and-play system. Raptor blades self regulate their speed in high winds.

Our 500 Watt grid tie inverter and Missouri Rebel 7 Blade Wind Turbine along with our diversion dump load makes for the perfect grid tie kit for medium wind zones (zones 2 and higher).

Simply mount the wind turbine on a 1 1/2″ pipe and wire it to the inverter. Then just plug the grid tie inverter into any GFI outlet and start feeding FREE electricity throughout your house.

The kit comes with:
– 7 blade Rebel Wind Turbine
– 500 Watt grid tie inverter (comes with a 30 day warranty)
– Diversion dump load resistors.

You can upgrade the system by simply adding more inverters if you want to add more wind or solar. The inverter will accept solar input as well. The dump load acts as a slow break in high wind conditions and keeps the system continuously operating. See our solar grid tie kits to add solar power to your system.

Five Years After Chernobyl: 1986-1991: A Review

Normal Accidents analyzes the social side of technological risk. Charles Perrow argues that the conventional engineering approach to ensuring safety–building in more warnings and safeguards–fails because systems complexity makes failures inevitable. He asserts that typical precautions, by adding to complexity, may help create new categories of accidents. (At Chernobyl, tests of a new safety system helped produce the meltdown and subsequent fire.) By recognizing two dimensions of risk–complex versus linear interactions, and tight versus loose coupling–this book provides a powerful framework for analyzing risks and the organizations that insist we run them.

The first edition fulfilled one reviewer’s prediction that it “may mark the beginning of accident research.” In the new afterword to this edition Perrow reviews the extensive work on the major accidents of the last fifteen years, including Bhopal, Chernobyl, and the Challenger disaster. The new postscript probes what the author considers to be the “quintessential ‘Normal Accident'” of our time: the Y2K computer problem.
