Product Overview
Description
Product Description
This kind of wind and solar hybrid streetlight controller is special design for small off-grid wind solar hybrid generation system. Appearance is elegant, operations are easy. It also makes the course of which wind generator and solar panels charge to batteries safely and efficiently.
Function and Features
> Protect wind generator from over-current
Once the wind current is over the setting max current, PWM intelligent dumping will start automatically. That protect wind generator.
> Intelligent limiting of batteries max current
According to the actual of the system, you could set batteries capacity on controller. The controller will calculate the maximum charging current (It’s 0.3 times of the battery’s capacity) . Then batteries will be protected.
> Function of manual brake
> Wind charging manual switch
On the controller you can manually set whether using wind charge to battery.
> Solar charging manual switch
On the controller you can manually set whether using solar charge to battery.
> DC output manual switch
Users could manually set whether use DC output.
> DC output has 4 working modes
> Boost function or buck function for constant current load is optional
> RS232 or RS485 interface
By RS232 or RS485 serial interface communication, you could monitor the whole system, storage and analyze data.
Program could be upgraded by serial interface.
Connect PC and controller by serial interface. You could set the parameters on PC and controller simultaneously.
Software is free, easy to operate and no need to be installed.

FAQ
Q: what is the boost function?
A: it is desinged for low voltage output wind generator, which can automatically work after setting the boost starting voltage, such as if your wind turbine rated voltage is 24V, while boost start voltage setted 20V, the controller will start to charge the battery while it detected the wind output voltage meets 20V. It will take full use of the wind power.
Q: what is the buck function?
A: it is desinged for high output voltage eind generator.
The controller will start buck function automatically once the real -time rectified DC Current is higher than rectified DC Current at Rated Power (.Cause the wind turbine will be burnt once the real-time rectified DC Current is too high, )
The buck function will convert the high voltage (U1) and low current (I1) from generator (DC, after rectifying) in the low voltage (U2) and high current (I2) to battery .
Q: how do I know which function is necessary for my system?
A: normally we need know the basic information of the wind turbine, rated output voltage and maximum output voltage. If you don't know exactly, just ask your turbine supplier; or kinldy provide us the power curve and voltage curve of wind turbine for checking by ourselves.
Q: What is the RS232 communication function?
A: it is for setting and checking the parameters of wind turbine, battery, controller from computer. Software free.
Q: What is the USB data logging function?
A: It is designed for collecting parameters of wind turbine, battery, charge controller from controller into USB flash disk. You can check it on any others computer.
Q: can I by 1 pc sample? what is the price?
A: of course, you can buy 1 pc, we always welcome clients to buy 1 pc as sample to make the test firstly. Then they will make sure this is good choice or not for their system.
