Regarding on how to choose solar hybrid controller: Fan power needs consistent with the solar hybrid controller,while the solar panel power within the range of solar hybrid controller.


For example: 
1) Solar panel power in less than 300w, fan power is 300w, You can match 300w solar hybrid controller;
 
2) Solar panels power in less than 300w, fan power is 400w, You can match 400w solar hybrid controller;
 
3) Solar panels power in less than 400w, fan power is 400w, You can match 400w solar hybrid controller.

 

Product Features

 

  • Wind and solar controller is designed for wind, solar power system design ; sets of wind control, solar intelligent controller in one . Equipment can not only efficiently transforming power of wind turbines and solar panels to charge the battery issue , but also provides a powerful control functions.
  • The controller uses PWM stepless unload mode control fans and solar intelligent battery charging . When the solar panels and wind power generators issued exceeds the battery storage capacity, the control system must be excess energy consumed , thus ensuring optimum battery charging characteristics, making full use of power .
  • The controller can not be charged in the conventional low speed , the controller has a boost function ( custom needs ) , better utilizing wind energy .
  • Because the battery can only withstand a certain charge current and float voltage , over-current and over-voltage battery charging will cause serious damage. Real-time detection of the controller through the microcontroller battery charging voltage and charging current and charging current by controlling the blower and photovoltaic battery charge current to limit the charging voltage and charging current , ensure that the battery can be filled with either , and would not be damaged. Thereby ensuring that the battery life.
  • Digital intelligent control , the core device features a powerful single-chip control , making the peripheral circuit structure is simple, and the control method and control strategy flexible and powerful ; power devices are made of high quality imported components , thus ensuring excellent performance and stability control .
  • In addition , the controller has complete protection functions, including : lightning , solar anti-anti- charge, over-voltage over-current automatic brake , reverse battery and open circuit protection.
Product installation and wiring:
 
LCD default interface

Press the button to enter the following screen, the cursor blinking in the first row, this time will Enter Operating Mode and Time Control

 
Set the operating mode , home on behalf of household mode , lamp streetlight representatives mode, each time you press the transformation once, after setting a good job mode , wait a few seconds release the button , the cursor automatically jumps to the second line , second line for the street light mode, you can set the time , every time you press the button , the time plus one hour , if it is please ignore household mode , wait a few seconds after the automatic return to the default interface, set successfully.
Installation and Use : Please Appendix wiring, please note that "+" " - " polarity , battery first pick , followed by wind generator and solar cells, last by the load. LCD display battery voltage and battery charge status.
1. Mate battery positive and negative ( positive fuse located on the left side prohibit a wrong )
LCD screen is connected properly initialized Happy , red led flashes, after completion of the output light ( green led) long bright . Undervoltage , overvoltage long off. Otherwise, check the line.
2. then connect the solar panel as shown ( left positive prohibit a wrong ) Appendix connected correctly, charging the president or flashing lights (red led). Otherwise, check the line. ( Two routes access panels , each rated to withstand normal current value ) .
3. finally connected load ( Appendix bulbs , cathode left ) , properly connected light bulb ( type street lights off during the day long . Undervoltage , overvoltage long off ) . Otherwise, check the line.
 
Note : A, above 1,2,3 points , in the order received ( overvoltage, undervoltage , charging , etc. Please refer to the basic parameters ) .
B, set the controller installed in the ventilation environment.
C, select sufficient capacity cables , to avoid too much wear and tear on the line , causing the controller to misjudgment . ( Do not connect the inverter output of the load directly connected to the battery , it may affect the controller work . )
D, the battery at least once a month to be filled , otherwise the battery will be permanently damaged. Be greater than the charge and discharge , the battery can is filled. When users configure the system , keep in mind this.

Failure analysis
1. Q: The fan speed immediately become very slow after it connect to the controller?
  A: 1.The battery voltage reach to the float voltage
 2. Rated output voltage of the fan is higher than the rated voltage of the battery, because the fan speed is proportional to the output voltage, the fan voltage will be hold by battery voltage and not very high, so the speed will be very slow.
 3. Uninstall tube was burned by a erroneous operation.
2. Q: Why will the controller uninstall when the LCD display smaller current value?
  A: Controller through the detection of battery voltage and charging current two parameters to control unloading, reach float voltage point, regardless of how much charge current, the fan will uninstall.
3. Q: LCD does not display?
  A: 1. The battery connection is bad, check the battery cable.
     2.The battery is damaged, please check and replace the batteries.

Digital display:

 
1. Intelligent design, simple structure, control powerful, stable performance, safe and reliable products.
2. optional large-size LCD display, all parameters visible and intuitive user
3. humane key operating functions, all parameters can be adjusted according to user requirements to facilitate customers to use in various environments
Custom features
4. with a variety of output state setting function, often power / half power / time periods, etc.
5. LCD battery voltage and charging current
6. digital intelligent control.
 
Perfect protection
 
1. Solar reverse charge, at night, such as poor light conditions, the battery voltage may be higher than the terminal voltage of the solar array. The controller with anti-reverse charging way to prevent the battery charging solar cells produce anti.
2. Battery Battery reverse polarity protection, the equivalent of a short circuit occurs, it will have a huge transient currents. The controller in the careless reverse, the circuit will automatically fuse blows, making the entire loop disconnect the battery, so as to effectively protect the battery and the device
3. battery open-circuit protection after long-term use, the battery may be open or poor contact occurs. The controller protects the battery open the device itself is not damaged
4. In the case of overload overload controller will automatically cut off the circuit.
