1、Good Functions: Built in industrial microchip with good storage function. Large screen LCD display, adjustable charging and discharging parameters. Using advanced digital power technology, the circuit energy conversion efficiency is as high as 98%. 2、High Charging Efficiency: The built in maximum power tracking algorithm can significantly improve the energy utilization efficiency of the photovoltaic system, which is about 15%‑20% higher than the traditional charging efficiency. 3、Multi Peak Tracking Technology: Dual wave or multi peak tracking technology, when the solar panels are shaded or some of the solar panels are damaged, multiple peaks will appear, and the controller can still accurately track the maximum point power. 4、Multiple Protection Functions: Internal overcurrent and short circuit protection, open circuit protection and reverse connection protection are all self recovery, lossless controllers, dual MOS reverse current protection, and low heat generation. 5、Multiple Tracking Algorithms Combined: The combination of various tracking algorithms can accurately track the proper working point within 1 second, and the MPPT tracking efficiency can reach up to 99.9%. 6、Current Limited Charging Mode: When the power of the battery panel is too large and the charging current is greater than the rated current, the controller automatically reduces the charging efficiency to make it work at the rated charging current.
