Wind Turbine Controllers
Wind Generator Hybrid Controllers.
The wind/solar hybrid street light controller is an intelligent apparatus which is specially designed for high-end small-scale wind/solar hybrid systems, and especially suitable for wind/solar hybrid street light system, and wind/solar hybrid monitoring system. It can simultaneously control a wind turbine and solar panels to charge a battery safely and efficiently. With neat appearance, easy operation, visual LCD display and many protection functions, the apparatus has high charge efficiency, and low no-load loss. The system operation will be safe, stable and reliable. With high value performance and a long life-span, it has already been widely accepted. The wind/solar hybrid street light controller is the most critical part in off-grid street lighting systems, and it’s performance affects the longevity and stability of the whole system, especially the life of the battery.
Reliability: Intelligent, modular design, simple mechanism, powerful functions. With industrial range superior components and strict production technology, the controller can be used in relatively bad working environment and has reliable performance and long life-span.
PWM Stepless Dumpload Mode: When the power generated by wind turbine and solar panel exceed battery capacity, the controller will release residual power. Common control mode is to dumpload all the power. However, the battery is not full actually. That all the power was consumed via resistors makes resource tremendously wasteful. Even with staging dumpload, it can be just divided into five to six stages, the effect is still unsatisfied. Our company adopts PWM (Pulse Width Modulation) stepless dumpload mode. In another word, the controller can dump residual power with division into thousands of stages. It can dump residual power while charging battery banks, which is benefit to effectively extend battery longevity.
Voltage Limiting and Current Limiting Charge Mode: When battery voltage exceeds the pre-set dumpload voltage point, the controller will adopt PWM voltage limiting charge mode. It dumps the excess energy in order to extend the battery longevity. When wind turbine charging current exceeds pre-set brake current point, the controller will automatically start brake to protect battery. (e.g.: WWS06-48-N: If battery voltage exceeds charge shutoff voltage or wind turbine current exceeds wind turbine brake current, the controller will automatically start brake.)
Two DC Outputs Mode: Each DC output has various control modes for choice, including: Constant on; Constant off; Constant half-power; light-control on, light-control off; light-control on, time-control off; light-control on, time-control half-power, light-control off; light-control on, time-control half -power, time-control off. Users can set three output control modes by LCD buttons: constant on; light-control on, light-control off; light-control on, time-control off.
LCD Display Function: The LCD screen displays system status and parameters via both digital and graphic forms. Displayed are: battery voltage, wind turbine voltage, PV voltage, wind turbine current, PV current, wind turbine power, PV power, load current, output control.

Wind Generator Controllers for over 2 kw:
This advanced wind/solar hybrid controller is specially designed for high-end small-scale wind/solar hybrid systems, and is especially suitable for wind/solar hybrid power generation system systems, and as a wind/solar hybrid monitoring system. It can simultaneously control a wind turbine and solar panels on the same battery, offering safe and efficient charging.
The controller adopts PWM to control both wind turbine and solar panel charging of the battery, with both voltage limiting and current limiting; namely, the controller will charge the battery with current limiting when the battery power is low, and charge the battery with voltage limiting when the battery power is high.
- When the total charge current of the wind turbine and solar panels is lower than the current limiting point, the controller will charge the battery with the whole of the power generated by the wind turbine and solar panels. However, when the total charge current of the wind turbine and solar panels is more than current limiting point, the controller will charge the battery only up to the current limiting point, the excess energy being unloaded by PWM.
- When the battery voltage is lower than the voltage limiting point, the controller will charge the battery with the whole of the power generated by the wind turbine and solar panels. As the battery voltage climbs up to the voltage limiting point, the controller will only charge battery up to the voltage limiting point, and the excess power will be unloaded by PWM.
For specific wind turbines, the controller can achieve accurate speed control, namely, you can set the stop rotation speed. When the wind turbine exceeds this speed, the controller will stop the wind turbine working, and the controller will not run the wind turbine for 10 minutes.
The controller has an LCD module especially designed for wind/solar hybrid system display. The LCD can display battery voltage, wind turbine voltage, PV voltage, wind power, PV power, wind turbine current, PV current and battery power status. Users can browse the parameters through the four keys of LCD.
The controller is equipped with dedicated remote monitoring software. The software can monitor system status in real-time, such as battery voltage, wind turbine voltage, solar battery voltage, battery charging current, wind turbine charging current, solar charging current, battery charging power, solar charging power, wind turbine charging power, fan speed and so on. The software can configure and modify the system parameters, and the software can control the operation of the wind turbine and the load.
In addition, the controller has built-in protection functions, including: solar panel reverse charging, solar cells anti-reverse, battery over charge, battery anti-reverse, lightning protecting, wind turbine current limiting, wind turbine automatic brake and manual brake.
A low-voltage charging module is optional. This module enables the wind turbine to charge the battery at low wind speeds. Because the wind turbine has low energy at low speed, the charging current will be small when the fan speed is slow. The low-voltage charging module enables the wind turbine to charge the battery with constant input impedance under low-voltage charging status, namely, the charging current is proportional to charging voltage. Depending on the different characteristics of wind turbines, the input impedance can be modified through serial communication. In addition, users can set wind turbine start charge voltage point through serial communication. Only when the wind turbine voltage is greater than the wind turbine start charging voltage, the wind turbine will charge the battery. The wind turbine start charging voltage can be modified through the serial communication. The controller has intelligent and modular design, simple menu, and powerful operation. The controller uses all high quality industrial components and controlled production activity, which makes the controller suitable for relatively harsh working environments, giving reliable performance and a long service life.
