1. New design of wireless remote-control can modify the controller parameter and read the system message
    according to the handheld device.
2. Digital high precision constant-current control, the maximum efficiency can reach 96%.
3. The working current can be adjusted from 0.15A to 3.3A, the regulating precision is 30mA.
4. High dynamic performances of load insure current output stability even though the battery voltage and load
    sudden change. 
5. 3 section time frame dimming function design, work time can be set range from 0h to 15 hours, power can be
    set range from 0% to 100%.
6. Intelligent power mode, the load power can be adjust automatically according to the battery power, can extend
     the maximum working time of the battery.
7. Record the system status, can record at a max 7days and monitor the whole system.
8. The true constant current but not limited the current, insure the current output stability thus decrease LED light failure,
     increase the LED service life.
9. Metal case, IP68 waterproof degree, can suitable use in all kinds of bad conditions.
10. With modified calculation of charging, the charging efficiency is improved, which lengthen the using time of solar energy. 
11. Overheat preventing function, above a certain temperature will decrease the load or close the load.
12. Varies system protection function. Including the battery reverse connection, LED short circuit, open circuit protection and so on.
