Solar lamp controller is used in solar photovoltaic system. It is called solar charge and discharge controller. It coordinates the work of solar panels, storage batteries and loads. It is a very important component in photovoltaic system.
Automatic Solar Street Light Controller
The maximum conversion efficiency of the Automatic Solar Street Light Controller is 96%. Its fully-sealed waterproof design and wide output voltage are suitable for most LED solar street lights.
What is Solar Lamp Controller
The solar controller is the heart of the solar system. This device decides when to switch on or off the lighting and charging. Smart controllers have built in functionalities to control lighting, dimming and battery charging. The smart controller prevents the solar battery from overcharging and undercharging. By receiving the energy from solar panels it continuously charges the battery during the day. During the night the controller supplies the stored power to run the LED street lights. Smart controllers can support single load or multiple loads.
Benefits of Solar Lamp Controller
Extend battery life
The solar street light controller adopts an intelligent power reduction algorithm based on the remaining battery power to ensure that the battery works in the best condition. This will greatly prolong the lifespan of the battery. At the same time, the controller also has high-precision temperature compensation function.
Voltage raising
The solar street light controller controls the output voltage from the output terminal. Regarding 24V system, if the battery voltage does not reach the 36V, required voltage for normal lighting ON, the controller will raise the output voltage to achieve the lighting requirement. This function must be realized by the solar street light controller.
Ensure constant current output
The LED needs constant current or current limiting by technical means to perform normal work. Usually the LED lights are powered by an external drive power for constant current of the LED.
Time control function
A single night can be split into three-stages. Each section lights for several hours, generally 3 hours + 3 hours + 2 hours configuration, a total of 8 hours. Of course, you can also set it to only light for 6 hours.
Solar lights operate on the principle of converting solar energy into electrical energy, completely separate from the conventional power grid. Therefore, the system components, structure, and control methods of solar lights differ from those of regular lights. To help customers understand how to control solar lights better, let's delve into the details of the solar light controller's structure.
Each type of solar light will have different structures and designs. However, the solar light controller typically includes basic function buttons, such as:
On/Off button: This button functions to turn the device on or off. Users press the On button to start the system and the Off button to deactivate it.
Auto button: In addition to the On/Off button for manual control, solar lights are designed to operate automatically. By pressing the Auto button, the solar light system will automatically turn on at night and turn off during the day to charge the battery.
6h, 8h, 12h buttons: If you see buttons labeled 6h, 8h, or 12h on the solar light controller, these allow you to adjust the lighting duration to suit your needs. The solar light system is designed to illuminate at night and turn off during the day. If you do not want the light to shine all night, you can press one of these buttons to select the desired lighting duration. This can also be understood as the timer function of the solar light.
Brightness adjustment buttons: These buttons enable you to adjust the brightness of the light. You can increase or decrease the light intensity according to your needs. This helps save costs and energy, especially in adverse weather conditions. The brightness adjustment buttons on the solar light controller are typically marked as + and -.
The Role of the Solar Lamp Controller
Control
The primary function of the solar street light controller is control. When the solar panel receives sunlight, it charges the battery. At this time, the controller automatically detects the charging voltage and outputs the appropriate voltage to the solar lamp, causing the solar street light to illuminate.
Voltage Stabilization
When sunlight hits the solar panel, it charges the battery, but the voltage can be very unstable during this process. If the battery is charged directly, it may reduce its lifespan and could even cause damage.
The controller includes a voltage regulation function that limits the input voltage to the battery through constant voltage and current. When the battery is fully charged, the controller can either reduce the charging current or stop charging altogether.
Boosting Effect
The solar street light controller also has a boosting function. When the controller cannot detect the necessary output voltage, it can control the output voltage from the terminals. For example, if the battery voltage is 24V but 36V is required for normal lighting, the controller will boost the voltage to enable the light to function. This function is essential for the solar street light controller to ensure that the LED light operates properly.
The Solar Lamp Controller has two ways to control time
Light Control
Light control is a basic, convenient, and versatile method. This controller does not require manual time adjustment; it automatically senses the intensity of light to turn the lamp on and off.
After installation, there's no need to adjust the on and off times according to the season; the light automatically turns off during the day and on at night. This type of control is widely used in lithium-ion solar street lights.
Some customers may ask if the street light will automatically turn on when it's cloudy. This depends on the extent of cloud cover. Under typical cloudy conditions, it will not light up; it usually only illuminates under extreme conditions. However, in situations that do require lighting, solar street lights have an advantage over commercial LED street lights, as they can still operate in severe weather due to their safe 12V voltage, which minimizes the risk of leakage.
Time Control
Time control is another common method for managing solar street lights. This involves setting a specific time for the lights to turn on or off. While this method is more complicated than light control-requiring adjustments based on the season to ensure timely activation-it allows for more precise operation. More advanced time-controlled controllers now offer remote modification of the timing.
Through these two basic methods, different combinations can be created, such as light-controlled lighting combined with time-controlled lighting. solar street lights primarily utilize light control, so customers do not need to worry about timing, which helps prevent unnecessary electricity waste and keeps overall costs lower.
When we talk about time adjustment, customers generally refer to solar street light controllers or solar intelligent controllers for off-grid solar systems. These provide continuous output for 24 hours without requiring users to adjust the working hours. If there are special requirements, a timer can be installed on the load side to manage switching on and off.
Over-Current and Short-Circuit Protection
The solar controller provides protection against over-current and short circuits.
Over-Voltage Protection
The controller automatically shuts off the output when the voltage is too high, protecting the equipment from damage.
Lightning Protection
In the event of a lightning strike, the varistor can prevent damage and protect the controller.
Battery Reverse Connection Protection
If the battery's positive and negative terminals are reversed, the controller can correct the connection and continue to function.
Battery Open Circuit Protection
If the battery is open-circuited, the solar power controller will limit the voltage at both ends of the load to protect it from damage. If the controller does not receive power during the night or when the solar panel is not charging, there will be no action.
Overcharge Protection
When the charging voltage exceeds the protection voltage, the controller will automatically disconnect the battery from charging. Once the voltage drops to the maintenance level, the battery will enter a float charging state. When the voltage falls below the recovery voltage, the float charging will stop and the system will enter the equalization charging state.
Over-Discharge Protection
When the battery voltage drops below the protection level, the controller will automatically turn off the output to protect the battery. Once the battery is recharged, the power supply will automatically resume.
Self-Checking Function
When the controller is affected by natural factors or improper operation, it can perform self-checks to inform the user whether the controller is functioning normally, thereby reducing unnecessary work hours.
Recovery Interval
To prevent load fluctuations caused by line resistance or battery self-recovery characteristics, the solar controller implements a recovery interval for overcharging or over-discharge protection.
Temperature Compensation
By monitoring the battery temperature, the charge and discharge values are adjusted to keep the battery in an optimal working state.
Light Control
Primarily used in automatic lighting fixtures, the solar controller automatically turns off load output when the environment is bright enough and automatically turns on the load when the surrounding environment dims, achieving automatic control.
