The Shangqiu solar street light controller 
 The the Shangqiu Institute of optoelectronic devices, "clean" brand of the PWM-15A type with clear instructions, with a reset function, when the battery voltage is below 10.8V, the controller automatically turn off the load, over-discharge recovery voltage: 11.8V. When the battery voltage is above 14.5V, the controller automatically turn off the charging power supply in order to achieve the purpose of protecting the battery. 

 "Clean" brand PWM-15A series waterproof solar street lamp controller 
 For one, the controller operating current: 5A/10A/15A. 
 Second, the controller has 12V/24V automatic recognition (in the case of supply 12V/24V solar light compatible). 
 Third, the controller has a waterproof, moisture-proof characteristics. 
 4, the controller can be set to control state of pure light. 
 5, the controller can be set to light control + time control status. 
 6, the controller can be set for three hours to control the output state. 
 An evening lit light source (solar light) turns off the light (solar light), late at night, dawn lit the light (solar light). 
 Control 2. Evening full power of the light source, the middle of the night to control the light source half-power, control dawn light full-power operation. 
 7, the controller has a dual-output function, supporting the use of more convenient. 
 8, the controller with wind and solar, more complete. 
 9, the controller has a floating charge, over discharge the automatic recovery, temperature compensation, the PWM pulse width modulation charge. 
 10, the controller has over-voltage shutdown, low voltage shutdown, over-discharge shutdown, load and battery reverse short circuit of solar modules, load short circuit, overtemperature Overvoltage night backflow and other functions.
