The world’s most cost-effective small wind
generator. The Whisper H20 is ideal for
charging batteries for cabins, boats, ham radios,
telecommunications, remote monitoring, cathodic
protection, oil platforms and rural electrification.

The sleek aerodynamic blades sweep an area 20
square feet (1.8 sq/m) providing 53 kwh/month in a
12 mph ((5.4 m/s) average wind speed. Our smallest
wind generator makes twice as much electricity as
the competition. Select the Whisper H20 when you

real

need

power.

Compare: twice the area = twice the electricity
