“WHISPER 200 - WIND CHARGE CONTROLLER”
WHISPER 200 WIND CHARGE CONTROLLER
The Whisper 200 charge controller is an intelligent Wind Charge Controller to provide the
safest, secure and productive wind generator operation. The Controller mechanism includes
the monitoring of various parameters like battery voltage, battery charging, load diversion,
auto manual setting, cumulative kWh, etc. The controller is PWM (Pulse Width Modulation)
type charge control logic.
The Controller contains 3 phase full wave rectification for battery charging and PWM type load
diversities system. The system continuously monitors certain vital parameters i.e. voltage
current power etc.
SPECIFICATION :
1) The Wind Charge Controller – Whisper 200 - is well-suited for 12V / 24V / 48V.
2) Clear alpha-numeric digital LCD screen with user selectable display options.
3) Equipped with advanced microcontroller based technology to provide easy access for

The Whisper controller is equipped with latest PWM (Pulse width modulation) technology to
slowly lower the charging energy applied to the batteries as the batteries get closer to fully
charged. This topology allows the batteries to be more uniformly charged with less stress on
the battery, extending battery life. It also keeps the batteries in a fully charged state by
adjusting pulse width (called float mode).
WHISPER CONTROLLER – MOUNTING
PRELIMANARY MOUNTING INSTRUCTIONS FOR WHISPER CONTROLLER
Please note that for preliminary turbine to controller tests; it may be convenient to temporarily
mount the Whisper Controller close to the wind turbine. This will allow the user easy access to the
controls and displays while testing the turbine and controller functionality. Please observe the
following recommendations for mounting the controller. The tests to be performed prior to mounting
the blades.
MOUNTING :
The Whisper 200 controller can be mounted vertically on the wall or horizontally on the Rack
or Table. Keep adequate rear space for cooling the power devices used in the Whisper
controller.
The diversion load is mounted inside the charge controller, itself.
WHISPER CONTROLLER – WIRING
1. First check the battery voltage and
polarity, then connect the battery
connections B + and B –
terminals.
(CAUTION:
It
is
strongly recommends connecting
the controller to the batteries
BEFORE making wind turbine
connections.
2. First check whether the wind
turbine is freely rotating or not. If
it is rotating smoothly, then brake
it by an external brake switch.
Now, connect the three wires from
Wind turbine at W1, W2, W3
terminals.
3. Connect Anemometer connection
at the three pin connector as
shown in the figure.
Refer to the wire selection table to select correct wire size to battery and wind turbine with the
controller.
The size of the wire required to connect the Whisper 200 controller to the wind turbine is
determined by the maximum power produced by the wind generator, system voltage and the
distance between the wind generator and Whisper 200 controller and also include the height
of the tower. Consider Whisper 200 wind generator is 1000 W having the maximum efficiency
of around 95 % in an area with a 12 mph average wind speed.
To use the charts, measure distance from Whisper 200 charge controller to wind generator,
find the closed distance listed in the column for your system voltage and read the wire size to
the left of the distance.
Note: If your measured distance is nearly midway between the two distances on the
chart, it is always better to select the larger size wire. This is particularly true in order with
higher wind speeds. Distances are listed in both feet and meters.
CHARGE CONTROLLER OPERATION
The AC power generated by the wind turbine is harnessed by using suitable size copper
conductors and carried out to the wind controller. The wind controller initially converts 3
phase AC input in DC using bridge rectifier. The bridge rectifier then supplies the DC power
through the suitable protecting devices like over current protecting device, etc. The controller
monitors the battery bank voltage contiounlsly and the dump load. The dump load is
gradually connected to the wind power so that it does not load wind turbine in one shot and
then current to the dump load increases as voltage builds up on the battery. PWM technology
is utilized to control the power to the dump load.
