China mining Wind and solar hybrid controller with good quality
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 hybridcontroller 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.
Performance Features
1. Superior military-grade components to ensure the product stability.
2. Perfect protection function, thus the system has higher reliability.
3. Check and set all operation parameters as requirement from LCD display.
4. Voltage limiting and current-limiting charge mode ensures battery in the best charging status.
5. PWM stepless unload mode, which burn the excess power into dump load, making the battery
charging in best status.
Qualifications
1. Utility model patent of anti-strong-wind, stepless unload wind power controller
2. Utility model patent of wind power boost charge circuit.
3. Utility model patent for integration of rectification and unload in wind power main circuit
board.
4. European CE certification.
5. Software product register certification
Optional Functions
1. Temperature compensation function: the controller can automatically adjust dumpload voltage
according to different external environment temperature, which ensures battery charge efficiently.
2. 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.
3. RS communication function: RS232/RS485/RJ45/GPRS are optional communication ports.
4. Output dry-contact signal function: the controller can output dry-contact signal
(e.g.: start diesel engine, gasoline engine signal).
5. SD card function: with SD card, controller can store system history data when it is
disconnected with PC.
6. Wind speed detection function: the controller can detect real-time wind speed;
the real-time wind speed value will be displayed via monitoring software.
7. 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.
8. 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.
