SR-LG4860 – PWM SOLAR CHARGE CONTROLLER (12/24/36/48V, 60A)

Product Enquiry

FEATURES

  • Common cathode design adopted.
  • LCD screen for displaying system working status and parameters.
  • Adjustable charge and discharge controlling parameter.
  • Boost Charge mode auto shifts on when the battery voltage is lower than boost charge return voltage.
  • Double temperature sensors design, inner sensor for inside temperature detection, and the outer independent sensor for detecting battery temperature which makes the battery temperature compensation more precise.
  • The controller can work out daily battery charging and discharging capacity which makes it more convenient to evaluate controllers and the whole system.
  • It possesses overcurrent protection when charging which can decrease the charging current so as to protect the charge circuit if it exceeds the rated current.
  • It will proceed equalizing charge every 30 days to protect the battery from vulcanizing.
  • Industrial grade chips and precision components adopted which can work under cold, hot and moist conditions.
  • Double MOS in series circuit adopted in charge circuit, PWM charging control to improve charge efficiency.
  • Power-fail protection for saving tech data which makes the system operation more reliable.
  • 3 different load working modes: Pure light control, Lighting + Timing control, load open all time.
