MAX20-EU

20A PWM SOLAR CHARGE CONTROLLER

PWM, 20A/20A, 12V/24V auto,
LCD display, 5V2A USB*2, IP32

  • LCD display design, read operating data and working condition easily.
  • Real-time energy statistics function.
  • 12V/24V automatic recognition
  • AGM,Liquid and GEL battery for selection.
  • External temperature sensor, automatic temperature compensation.
  • Built-in temperature sensor, when the temperature exceeds the set value, the charging current will lower down followed by the decrease of temperature, so as to control the controller’s temperature rise.
  • Four stages charge way: fast, boost, equal, float.
  • Multiple load control modes: Standard, Dusk to Dawn, Timer and User-defined mode.
  • Two USB interfaces.
  • Perfect EMC & thermal design.
