Main features:
1.A new voltage-boosting, constant current LED Driver inside it and its efficiency is up to 91%-98%.
2.The output current is adjustable (dimming value of 10%-90%) on the machine and there are four  times to control light working, full power timer, second timer, third timer and four timer before sunrise.
3.Utilize SOC to exactly calculate the state of battery charging and discharging that can efficiently  extend the battery life.
4.It is with over-charge, over discharge, electronic short circuit and overload protection and LED open  circuit and short-circuit protection that will not damage any other parts.
5.It adopts PWM charging mode that 3%-6% higher than without PWM charging to extend working  time. Also it has temperature compensation function.
6.Visual LED display indicates the current, working time and power to make users understood the light  working condition.
7.All controllers are used industrial chips (only with I industrial-grade controller), can be regularly  working in cold, hot, humid environment. At the same time, are used the crystal oscillator to precisely  timing control.
8.Use of Flash memory to record controlling point to improve its accuracy and reliability;
9.Use the double-digit LED display and settings, one button to complete setting lighting control option,  which is extremely easy and intuitive to use.
10.Using high heat conducting silicon, with protection of IP66

Adjustable Lighting Control Options
20a manual pwm solar charge controllerRepresentatives of the two-digital control functions:
Such as: Lamp is 80W, with lamp of 10series and 8 parallels. Working hours are: 3 hours of full power, 3  hours of 60% power, 4 hours of 40% power, and 1 hour of turning on light before sunrise.
LED digital  display shows: 
12v solar charge controller
1.Set the first timer value to "03", means the first timer works 3hours (at100%power).
2.Set the second timer value to "23", means the second timer works 3hours.
3.Set the third timer value to "34", means the third timer works 4hours, then turn off the LED lights.
4.Set the lamp‘s parallels, and set value to "48" standing for 8 parallels and the output current is 2.4A.
5.Set the ratio of the second timer to "56" standing for 60% power
6.Set the ratio of the third timer to "64" standing for 40% power  
7."71" is the default value,special for factory test.
8. Set the fourth timer to ‘82", means that the light will turn on for 1 hour again before sunrise.
Instructions for use:
This section provides a brief overview of how to get started using the controller. However, please review the entire manual to ensure best performance and years of trouble-free service.
1. Mount the controller to a vertical surface. Allow space above and below the controller for air flow.
2. Make sure the PV and load currents will not exceed the ratings of the controller being installed.
3. Firmly fixed to the controller, mounting holes as shown:
Dimensions: 152X 82X46(mm)
Installation size:141 X 58Xφ4(mm)
N.W.: 0.80kg, G.W.: 0.85kg
4. Connecting Order: Load wires→ Battery wires→ set lighting control options→ panel wires
4.1 Connected Load wires, pls note that + and - poles, in case to break out LED lights
4.2 Connect the Battery terminals to the controller, pls note the + and - poles, do not reverse. If properly connected, the indicator (2) should be bright. Otherwise, need to check if it is connected.
4.3 Connect solar panel wires, pay attention to + and - poles, do not reverse, if there is sunshine, solar indicator light should be on.
5. How to testing: Press the BUTTON to set 71 to 70, then LED light will turns on for 5 seconds. If LED light is on for more than 20 second, there is the problem to charge return load.
6. Note: After connecting all wires, users had better to fix the controller and KEEP it ERECT.Power-saving Mode: When controller is into normally working and without manual operating for 30 seconds, it is will in power-saving mode that all LED indicator lights are off. If users would like to check it, they need to press the button again.
Connecting Instruction:
12v solar controller
Note: please select right series and parallels of LED lights according to the above, or LED lights or controller may be broken down.
