1、High Efficiency: The maximum power tracking algorithm is adopted to significantly improve the energy efficiency of the system, and the charging efficiency is 15%‑20% higher than traditional PWM. 2、Accurate: Double or multiple peak tracking technology, when the panel is shaded or part of the panel is damaged, there will be multiple peaks, charge controller can still accurately track the maximum point power. 3、Multiple Protection: Internal overcurrent, short circuit, open circuit, backconnection protection are self recovery, lossless controller, double MOS reverse current protection, low heat generation. 4、Current Limiting Charging: With current limiting charging mode, when the power is too large and charging current is greater than rated current, solar controller automatically reduces the charging efficiency. 5、Easy Operation: Easy to operate, LCD display can clearly indicate the status and charge and discharge parameters are adjustable, without power storage function.
