 Whisper 500 48v (unit only)
Manufacturer: SOUTHWEST WINDPOWER
Item ID: 4924
Price: $6,341.25
Serious power from a medium size small wind turbine. The Whisper 500 can produce enough energy to power an entire home. Formerly the Whisper 175, the Whisper 500 was completely redesigned to work in harsh high wind environments. The Whisper 500 is a two bladed fiberglass reinforced blade 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.
