Features of the Whisper 100 and 200 Wind Turbine

Hardware Description

Both the Whisper 100 and 200 wind turbines are hardwired with the basic configuration of 24 volts. Additionally the buyer can hardwire the turbine with either 12, 36 or 48 Volts on the top of the wind turbine as shown in the following picture.

Both the Whisper 100 and 200 use the same DLCC unit.

The DLCC unit has a manual switch configuration setting for the use of 12, 24, 36 and 48 Volts.

Description of the Technical Problem with the DLCC unit

On the main board there are 4 IRFB4410 rectifiers soldered. The rectifiers can’t handle a low level Voltage input. This means that the “Gate” is not opening and is not charging the batteries on a hybrid system. For only a wind speed of 10 mph (4.4 m/s) and up will the “Gate” open and then charge the batteries.

In idle mode the wind turbine is running at 3.3 mph (1.47 m/s) to 9.9 mph (4.42 m/s). It is delivering power from the turbine but the DLCC unit is not opening the “Gate” and therefore there no charges to the batteries at low wind speed.

Over 9 months we have calculated, tested and measured that the Gate on the South West Wind Power DLCC unit. We conclude that the Gate is only opening at 400 Watts and a wind speed of 10 mph and up. In the moment when the wind speed decreases to 9.99 mph the Gate closes immediately and no power is charged to the battery.
