PWM solar charge controller

PWM, 10A/10A, 12V/24V auto,

LED display, infrared, IP67

12 volt solar charge controller


SMR-N5 series PCB are made from encapsulated and durable aluminum alloy material, which lead to its waterproof function (Ip67 protection degree), they can operate normally in various tough conditions.
With remote infrared unit equipped, it can set parameters, read status and view historical data easily.
12V/24V system voltage automatic recognition, 10A, 20A current.
Suitable for Liquid, GEL, or Lithium batteries.
SMR-N5 is a good choice for your solar street light system/home system or other solar monitoring systems in tough environments.

  • 5 stages time can be adjusted
  • Can read parameters and running status
  • Suitable for Liquid, GEL and Lithium battery
  • 12/24V system voltage automatic recognition (Liquid/GEL)
  • Automatic temperature compensation (Liquid/GEL)
  • Four stages charge way: fast, boost, equal, float(Liquid/GEL)
  • When BMS power off because of LVD, it can activate the system automatically(Lithium)
  • Charging target and charging recovery voltage can be set(Lithium)
  • Day/Night threshold can adjust automatically
  • Remote Unit to configure, with LCD display
  • IP67, Strong and durable aluminum case
  • Full automatic electronic protect function
