Solar street light controller is a microprocessor-controlled and displayed through intelligent charge controller, using high-quality, low-loss, long-life components to ensure reliable performance, so that long-term street lighting system can work to reduce the maintenance cost of the system, particularly greatly reduce battery maintenance costs.
JC series solar street light controller can adapt to the harsh working environment that can provide two-way access to the load, by setting the dual time function keys can be freely set the system settings and lighting working hours, automatically turn on or off according to the intensity of light load, can be used for LED, low pressure sodium lamp, metal halide lights, garden lights range of lighting systems.
- Microprocessor control, intelligent control of charging and discharging
- After the memory controller lost power on again, press the mode is automatically de-energized before work
- Light control + time control within one hour to 15 hours can be set to achieve timing fine
- With perfect battery overcharge and over-discharge protection
- With battery open circuit, overvoltage, output short circuit protection
- With solar cell reversal protection, anti-anti-charge function at night
- Undervoltage and overvoltage anti-shock protection, low no-load loss
- Temperature compensation function
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 solar cells, followed by the load. LCD display controller and the battery voltage and battery charge status , two LED charging indicator system , respectively , and discharge instructions.
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.

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
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.
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.
