Feature:1. Built‑in industrial microchip, with good storage function, large‑screen LCD display, can clearly indicate the status and data, adjustable charge and discharge parameters.2. The internal over‑current/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.3. 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 PWM charging efficiency.4. It has a current‑limiting 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 and makes it work at the rated charging current.5. Double-peak or multi-peak tracking technology, when the battery panel is shaded or part of the battery panel is damaged, multiple peaks will appear, and the controller can still accurately track the maximum power.Specification:Condition: 100% Brand NewItem Type: Solar Charge ControllerMaterial: ABS+ROHSColor: As shown in the pictureSize: Approx. 13.4x6.8x3.4cm / 5.3x2.7x1.3in Weight: Approx.160g~165g/5.6oz~5.8ozPackage List:1 x Solar Charge Controller1 x Instruction ManualNotice:1.
