Wind-Solar Hybrid Controller with LCD Display for Street Light (QW-500JN)
This controller uses PWM step less unloading way to control wind turbine and solar batteries intelligent charging of battery. When the energy generated by the solar panels and wind generators exceeds the battery storage capacity, the control system must be consumed the excess energy to ensuring optimal battery charging characteristics, so that the energy can be fully use.
The controller use a single-chip real-time detection of battery charging voltage and charging current limit and control the the fan charging current and photovoltaic charging current to the battery charging voltage and charging current to ensure that both the battery is full but not be damaged. To increase service life of the battery.
Digital and intelligent control, the core of the device using a powerful micro controller control, to make the periphery of the circuit structure simple and the control methods&strategies is flexible and powerful; The power devices of the controller using quality imported components to ensure excellent controller performance and stability.
In addition, the controller has perfect protection functions, including: Lightning, solar anti-anti-charge, over-voltage over-current automatic braking, the battery reverse and open circuit protection.
This inverter is good quality and beautiful design.
1. Control mode of Wind Turbine Open Circuit & Dump-loading; Over Rotate Speed limiting, Over Voltage & Over Current limiting.
2. Battery Maximum Charging Current Smart Limiting.
3. Wind/Solar Charge to Battery Independently; Complement Intelligently.
4. Every Controller Has Two DC Outputs, Each Output Has 9 Output Modes.
5. High effiency(94%), High power factor.
6. Intelligent PWM dimming(0-100%)
7. Good compatability, fit any LED street lights from any manufacturers.
8. Easy and convenient for installation and debugging.
9. PWM CV charging protects the storage batteries from being over charged and energy can be fully utilized
10. Microcomputer chip ensures accurate control
11. Perfect protections: Over charge protection, over discharge protection, reverse connection protection, PV cell panel reverse connection protection
12. Automatic brake and manual brake ensures that the wind turbine and the PV & wind hybrid charging controller operate safely and reliably
13. Voltage for automatic brake (rectified voltage of solar panel) and the recovery time after automatic brake can be adjusted in accordance with customers demands
14. High efficiency, soft braking, independent input circuits for wind turbine and the PV. As a result, if there is something wrong with one circuit, the other circuit can operate smoothly to provide stable power supply for load.
15. Controller for solar and wind turbine
Our wind&solar hybrid street light controller is a collection of solar energy, wind energy and output dimming control. It can control solar cells and wind generator at the same time to intelligent charging for the accumulator. It is equipped with two ways output with the function of two lamp control( moto lane and sidewalk) and PWM dimming. It is not only provide the necessary lighting especially the bad weather(cloudy and no wind), but ALS can save electric energy.
In addition, it has the function of light control and time control. Light control: When night approach it can automatica1ly open street lamp output and light the lamp. When morning comes, it can automatically shut off output and realize effective energy saving. Time control: We use the four dial code switch and freely set the discharge time of four power section(the whole power, two-thirds power, half power, one-thirds power), to reasonable distribute limited battery capacity, to greatly increase the span life of battery and single use time(a discharge cycle).
