“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 monitoring and operation for the user.

4) Field adjustable battery voltage set points.

5) Energy saving backlight operation.

6) Controller diverts extra energy to dumpload, when batteries are fully charged.

7) Battery over Voltage Protection. 8) Front panel LCD display, with following features -

i. Displays battery voltage, battery charging current, kW and kWh reading, battery UV and OV status, Instantaneous / monthly / average wind speed in m/s – if anemometer is ordered along with the controller.

ii. Supervisory Password Provision

iii. Auto Manual Selector switch

KEY FEATURES:

• Capacity 1000W 12V / 24V / 48V for Whisper 200. • PWM based state of art architecture providing overcharge protection / load diversion (in Auto mode)

• Status monitoring of battery low & battery high - LCD display on front panel. • Status monitoring Liquid Crystal Display on the front panel, displaying various parameters

• Modular construction for easy installation and dismantling. • Suitable for standalone or multiple parallel module application to suit different power rating.

• Powder coated - corrosion proof sheet steel box. • User select : auto or manual operation • Higher voltage charging option for equalizing charge (in manual mode) • Automatic braking mode at battery overcharge / very high turbine speed. • Suitable for Rack mounting and the Wall mounting. • Lightning surge protective devices. • Operating ambient upto 52°C.

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

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.

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.

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.
