ISO 9001 Certified 10A /20A /30A for you to choose Electronic for protection Fully automatic operation PWM charge mode(SOC) Micro-controller digital accuracy Suitable for all 12/24VDC lamps Big terminals,big distance between terminals Double digital LED display, numbers equal to timer setting Temperature compensation(with external temperature sensor)
Manual  
1. SAFETY 
Full consideration to the safety of persons and property has been given when designing the products.
However the incorrect connection may cause the system breakdown or even safety accident. For your 
safety and benefits, the following rules must be comped during the operation.
. Installation of this product shall be tinder the guidance of the professionals in this field. 
. Prevent this controller from water, humidity and insects, to avoid short-circuit. 
. Keep children and incapable persons away from the controller
. Keep the controller away from electrical heater, heating machine and other high temperature electrical 
appances; avoid the controller suffering from insulation directly. 
. Please check the rated voltage of solar panel, battery, and loads before connection. 12V rated voltage
 is 12V, 24V rated voltage is 24V, 48V rated voltage is 48V. 
. Make sure connections between positive and negative poles of Solar panels, Battery and Loads are correct. 
. The diameter of connecting cable must be matched with the requirements of the current. Do not use thinner
diameter cable, the thinner diameter. The larger resistance, this will cause higher temperature and output power
decreasing. 
. The total rated current of solar panel and loads must be smaller than the rated current of the controller. 
. Components of system must be correctly and firmly connected. Prevent the terminals from oxidation and moldy,
 to avoid connection trouble. 
 
Function:
. keep the battery on fill voltage condition. 
. Prevent the battery from over-charging. 
. Prevent the battery from over-discharging. 
. Prevent the battery from reverse charging to solar panels during nights. 
. Reverse Polarity for Protection for Battery
. Reverse Polarity for Protection for Solar Panels
. When the battery voltage is low, the controller will automatically cut off the load from the system. If the voltage of 
battery is back to normal and the load will restart working. 
. Thunder for protection
. According to the battery voltage grade, the controller can automatically set charge-off voltage, the load-off voltage, 
the load- restore voltage. (The parameter is default under 25 Celsius condition, locked by the CPU procedure, cannot adjust.) 
. The controller will automatically compensate the temperature of the charging voltage according to the changes of 
ambient temperature.
   
 
Warning:
Before connecting to the solar panel, please connect the controller to the battery; do not use solar panel supply power 
to the loads directly. 
Notes:
Do not use lampght to charge the solar panel (lampght is too weak to charge) 
for DC power source to replace the solar panel will cause troubles to controller.
Choose the suitable wire which diameter should not be too small, please refer to the parameter.
 
4. INDICATE LIGHT AND BUTTON. 
When Red LED (CHARGE) is on, battery is charged up strongly; When Red LED is fckering, battery is 
charged up in constant voltage; when Red LED is oft charge off
. When Green LED (LOAD) is on, loads are working; when Green LED (LOAD) is off, loads stop working. 
.Three Colorchanging LED (BATTERY), When ght is red, it indicates low voltage, green indicate battery full charged, 
orange indicate normal status. 
Color-changing LED working voltage indicates area: 
Color-changing LED 12V 24V Red LED 10.5V-11V 21V-22V Orange LED 10.5~11V-13.7V 21~22V-27.4V Green LED ≥13.7V ≥ 27.4V

6. TROUBLE SOLUTION 
Phenomenon:Green LED off, battery indicator LED is red. 
Reason: Low voltage of battery 
Solution: 
A:Cut off the power, disconnect the load; reconnect the load after the charge become normal. 
B:Battery charge problem: Increase the solar panel power or change the battery. 
Phenomenon:Battery indicator LED is orange and Load indicator LED is green, the loads cannot work. 
Reason:Over load or short-circuit causes the controller inner fuse cut off 
Solution: 10-20 minutes after eminated the malfunction, the fuse will automatically back to working.
