The Whisper 500 Grid Tie Package is a complete package ready to get you grid-connected and powered up in no time at all.  The Kit includes a Whisper 500 Wind Generator rated at 3000w, with a monthly output of over 500kwh, a Magnatek Inverter, and a Rectifier.

With the Inverter and the Rectifier, the Whisper 500 Grid-Tied Package is ready to output at 240VAC, and sell back any excess energy back to the utility grid through local net metering laws.  This allows the owner to effectively turn their meter backwards.  In fact, it is not uncommon for owners of Wind Generator Kits to have monthly electric bills of under $10.00, or even less.  In the right conditions, and with limited power consumption, you could have electric of $0.00 or less.
