TL12/2410LI-B step-down constant current solar charge controller

 

The controller is a step-down solar controller integrated with LED drive power supply. The max load is 70W LED lights. The conversion efficiency can be up to 95%. The product adopts fully sealed waterproof design, outputs constant current and has the function of 3 time frames power regulation. It can automatically adjust the load’s power according to the left capacity of battery, which increases the working time of the lights. One of the working modes of the controller is  automatical time controlling at dusk and dawn. Under this working mode, the light is off at midnight, so this mode is suitable for village roads or scenic spots. And under this mode, the controller automatically decides the time of turning on lights and tutning off the lights according to different seasons.

 

 

Features

2)      Apply to LED lights of 3 series (12V) and 6 series (24V), max power 70W;

3)      Automatically adjust the power of load according to the left capacity of battery;

4)      The controller has a function of automatical time controlling at dusk and dawn, according to different seasons;

5)      With the function of 3 time frames power regulation, Users can set the working current of LED lights;

6)      The controller adopts fully sealed waterproof design. The IP grade reaches IP67;

7)      Flexible and adjustable working parameter makes the controller adapt to different solar systems;

8)      This controller can withstand from -35℃ to 60℃ high and low temperature.

 

Scope of power decrease:

12V: If the voltage of battery is less than 12.5V, the controller begins drop power automatically. When the voltage of battery is from 12.5V to 11.8V, the output current of the controller changes linearly from 70%~30% of the setting value. (24V: double the voltage)

 

 

Application Scope:

12V solar LED lighting system with solar panels of max 170WP and 60W LED lights(the circuit of LED lights should be 3 series)
24V solar LED lighting system with solar panels of max 360WP and 70W LED lights(the circuit of LED lights should be 6 series)

TL series are intergrated with LED driver. That means the LED light needn’ t include driver, so the cost of driver is saved. TL series have the function of output current adjustable, and this function realize the load’ s power adjustable. For example, a 30W LED lights can work as follows: The first time period:           300minutes(5hours)            30W The second time period:       300minutes(5hours)            10W The third time period:               180minutes(3hours)            20W If you use ordinary solar controller, the 30W LED lights will work as follows: The first time period:           300minutes(5hours)            30W The second time period:       300minutes(5hours)            30W The third time period:               180minutes(3hours)            30W Thus TL series help save 130Wh.
Suppose the 30W LED lights works 13 hours a day. The sun time per day is 4 days. The rainy days are 7 days. Let’ s compare the configuration bewteen these two solar light system. Solar controller ordinary TL series Comparison Solar panel 285Wp 190Wp 95Wp Battery 3PCs 12V 120Ah 2PCs 12V 120Ah 1PC 12V 120Ah Conclusion: TL series help save solar panel 95Wp, battery 1PC 12V 120Ah. Thus the solar lights using TL will save a lot of money.
