Specifications

SCA Solar Charge Controller With USB (10-30A)
Controller is only applicable to the system which is solar energy with 12V/24V

 

General safety and usage advice
1. The battery saves large amount of energy, do not let it in short circuit in any case.We suggest to connecting the battery wire with fuse. (Slow motion type, in accordance with rating of the controller.).
2. Battery can produce combustible gas. Keep it away from the spark, fire or the flame which is without protection. Make the battery storage ventilated.
3. Do not touch or short-circuit the wire or terminal for some wires or terminals can produce the rating voltage which is two times of the battery. Insulation tools should be used when in operation.
4. Make sure to keep the children away from the battery and controller.
5. Please observe the manufacture’s safety advice.

Range of use
Controller is only applicable to the system which is solar energy with 12V/24V rating voltage. Battery is in plumbic acid with liquid openings or be sealed (by VRLA valve) and can also be ferrous phosphoric acid lithium. Note the type before you buy it.

Function  
1. 12V/24V Automatic identification by system
2. LED digital display and one-key operation, easy to use 
3. The improved 3-section computing method can weekly give the battery a Balanced charging. It can stop the battery from being unbalancing and vulcanizing and let the battery been used for more time.  
4. the controller is equipped with the serial PWM charging main circuit with additional 3%~6% efficiency than the non-PWM circuit which can work for more time and increase the using period of the system.   
5. Controller has three load work ways and can be easily used in varies streetlights and monitors.
6. Visualized LED display which can let the users get to know the conditions of solar power and storage battery. 
7. Overcharge, over discharge and overload protection; Electronic short circuit protection; Reverse connect preventing protection. 
8. Lightning prevention
