The medium-sized Whisper 500 can produce enough energy to power an entire home. Formerly the Whisper 175, the Whisper 500 was completely redesigned in 2004 to work in harsh high wind environments.

The Whisper 500 is a two-bladed fiberglass reinforced wind turbine and incorporates the patented side furling design that optimizes output at any wind speed. Assuming a 12 mph (5.4 m/s) wind, a Whisper 500 will produce as much as 500 kWh per month. That is enough energy to power the average home.

How the Whisper 500 works:

• The Whisper provides electricity to batteries in your battery bank.
• The electricity enters the battery bank through the Whisper charge controller. IT then travels through an inverter, which provides electricity to the home.
• Most utility companies will purchase unused electricity from the homeowner to supply back to the public at-large.
