MAX2024-U

20A PWM SOLAR CHARGE CONTROLLER

PWM, 20A, 12V/24V auto,
LCD display, Max volt on PV terminal 25V/50V/75V/100V , USB interface:5V/2A(Maximum).
Grounding:Common Positive.

  • 12/24 automatic recognition.
  • Perfect EMC & thermal design.
  • Full automatic electronic protect function.
  • Flexible System battery selection: Liquid, Gel, AGM and Lithium.
  • Equipped with lithium batter y activationfunction.
  • LCD display design, read operating data and working condition easily.
  • Built-in over-temperature protection mechanism; charging and discharging stop when the temperature exceeds the set value.
  • Lead-acid battery charging in four stages: fast charge, boost charge, equalization charge, float charge.
  • PWM charging is programmable to prevent system failure caused by BMS
  • Short-circuit protection is programmable to prevent output shutdown when disconnecting the capacitive or inductive loads.
  • Small size, PiD algorithm adopt to control the voltage output, make the control more stable and accurate.
  • The visual control point voltage and charging voltage can be set.
