INTRODUCTION:

The wind/solar hybrid controller is control device which can control wind turbine and

solar panel at the same time and transform wind and solar energy into electricity

then store to the battery bank. Wind/solar hybrid controller is the most important part

in off-grid system, whose performance has much effect on life expectancy and operational

stability of the whole system, especially the battery expectancy. Or life span of battery

will be shortened by over-charge or over-discharge.

APPLICATION AREAS:

Stand alone wind/solar hybrid power station.

Stand alone domestic household wind/solar hybrid power system.

Mobile communication base stations, expressway and other non-residential regions.

Coastal islands, remote mountainous, border posts for regions shortage of or without electricity.

Government demonstration projects, landscape lighting project.

PERFORMANCE FEATURES:

Superior military-grade components to ensure the product stability.

Perfect protection function, thus the system has higher reliability.

Check and set all operation parameters as requirement from LCD display.

Voltage limiting and current-limiting charge mode ensures battery in the best charging status.

PWM stepless unload mode, which burn the excess power into dump load, making the battery charging in best status. 

DATASHEET:

QUALIFICATIONS:

Utility model patent of anti-strong-wind, stepless unload wind power controller

Utility model patent of wind power boost charge circuit.

Utility model patent for integration of rectification and unload in wind power main circuit board.

European

CE certification.

Software product register certification

OPTIONAL FUNCTIONS:

Temperature compensation function: the controller can automatically adjust dump-load voltage

according to different external environment temperature, which ensures charge battery efficiently.

Wind turbine low voltage charge function: the controller can charge battery when wind turbine is

in low rotate speed status, which can make full use of low wind power.

RS communication function: RS232/RS485/RJ45/GPRS are optional communication ports.

Output dry-contact signal function: the controller can output dry-contact signal (e.g.: start diesel engine, gasoline engine signal).

SD card function: with SD card, controller can store system history data when it disconnected with PC.

Wind speed detection function: the controller can detect real-time wind speed; the real-time wind speed

value will be displayed via monitoring software.

Wind turbine rotate speed detection function: the controller can detect real-time wind turbine rotate,

the real-time wind turbine rotate speed value will be displayed via monitoring software.

Wind turbine micro-current charge function: when the wind turbine input DC voltage reach to the

pre-set value, the controller will produce small current charge battery.

OPTIONAL ACCESSORIES:

Ethernet communication module

GPRS communication module

SD card storage

RS485-USB converter

RS485-RS232 converter

RS232-USB converter

HELPFUL HINTS:

Customers, who will order the wind/solar hybrid controller, need to provide the following information:

Rated battery bank voltage

Rated solar power

Rated wind turbine output power

Whether the wind turbine is three phase AC output, single phase DC output or single phase AC output.

FAQ

Q1: What is the different between MPPT and PWM controller?

A: The PWM controller is in essence a switch that connects a solar array to a battery.

The result is that the voltage of the array will be pulled down to near that of the battery;

The MPPT controller is more sophisticated (and more expensive): it will adjust its input

voltage to harvest the maximum power from the solar array and then transform this power

to supply the varying voltage requirement, of the battery plus load. 

Q2 : What is the charging stage of your controllers?

 A :  They are 5-stage Charging, which are soft start, bulk charging, absorption charge,

equalization charge & float charge.

Q3: How can we recognize the MPPT and PWM controller?

 PWM

The PWM charge controller is a good low cost solution for small systems only,

when solar cell temperature is moderate to high (between 45°C and 75°C).

MPPT

To fully exploit the potential of the MPPT controller, the array voltage should be substantially

higher than the battery voltage. The MPPT controller is the solution of choice for higher power

systems (because of the lowest overall system cost due to smaller cable cross sectional areas).

The MPPT controller will also harvest substantially more power when the solar cell temperature

is low (below 45°C), or very high (above 75°C), or when irradiance is very low.

Q4: What is your application for the controller?

For the controller, we not only have solar controller, but also offer the wind controller, solar pump controller etc.
