There are two voltage settings in the Whisper controller that regulate the voltage delivered to the batteries The regulation on voltage is the voltage above which 100 of the turbine output is dumped into the resistor to protect the batteries from over voltage The regulation off voltage is that below which none of the power is dumped The primary function of the controller is to convert the 48V 3Phase AC output from the turbine to 48 DC for battery storage The controller is connected to the batteries via a key switch Note there must be an electrical load on the turbines either from the brake or the controller batteries at all times or they could spin excessively fast The 48V DC key switches should be turned off if the turbines are not in use as the controllers can drain the batteries Note the brakes should be on if the controller is switched off 3500 3000 5 2500 8 1500 8 1000 amp 500 0 mph 5 10 15 20 25 30 35 40 45 ms 23 45 68 9 0 11 3 13 5 15 8 18 0 20 3 Instantaneous Wind Speed Figure 12 Whisper 500 Output as function of wind speed Diversion Switch The diversion rocker switch is located on the top of the controller Figure 9 to the left of the green and red LEDs Setting the switch to OFF causes all the power produced by the wind turbine to be diverted the Diversion Load and the wind turbines will slow down The Whisper 500 utilizes an external Diversion Load Note The switch may not stop a rapid
