Solar Charge Controller Back CE Certified


  • Fully automated operation
  • 3 pairs of terminals (input, battery, output)
  • LEDs to indicate charging, output and battery capacity
  • Temperature sensor
  • Replaceable fuse to protect the system from damage
  • Metallic heat sink
  • Mounting holes for ease of installation

Specific Attributes

  • High precision voltage recognition and PWM (Pulse Width Modulated) algorithm to ensure charging is as efficient as possible whilst protecting your battery life
  • Temperature sensor to ensure your battery is charged optimally at all temperatures
  • Protection from over-charging and deep-discharging in order to maintain the longest life for the batteries
  • Cut out to prevent damage if battery or panel are incorrectly connected
  • Protection for the entire system against a short circuit in or other excess current to the output
  • Protection for the entire system against short circuit in the solar panel
  • LED indication of battery capacity including low-charge warning
  • LED indication to show when solar panel is charging the battery
  • Buzzer to warn of incorrect battery connection
