12V/24V AUTO PWM Solar Collector Controller   Light + time control solar street light controller 1. Control: Micro Controller Unit utilizing dedicated software for precise control. 2. Charging mode: Pulse Width Modulated control, allows for   high efficiency boost, recovery and float charging. Temperature compensation ensures that these parameters are adjusted for maximum battery condition and hence, prolonged battery life. 3. High accuracy discharging control: Over-discharging control voltage modified by the battery discharging rate curve. 4. Circuit protection: protection against overload, short circuit and reverse connection, Built in Transient Voltage Suppression protects against lightning. Reverse current leakage through PV panel is blocked. Batteries are prevented from over-charging or discharging. 5. LED indication on system condition: Indicating  LEDs,  monitor  battery  charging  levels  as  well  as  battery  state.  LED monitoring  of  load conditions such as over load and short circuit as well as load on/off, are also provided. Digital LED display number equal to time setting 6. Design standard:   Operating temperature range from -35 to +50 deg C. 7. No adjustable hardware:  Controller  accuracy,  stability  and  reliability  is  assured  by  the  use  of  flash  memory  for all  control parameters and set-points. 8. Operation: easy to operate, robust in design.   Specification:
