Solar Charge Controller 180V Input LCD Display MPPT Intelligent Solar Regulator 12V 24V 36V 48V Auto 50A Item Type: Solar Charge Controller No Load Loss: ≤0.4W Rated Load Current: 20A Conversion Efficiency: ≤98% MPPT Tracking Efficiency: >99% Temperature Compensation Coefficient: -2mv/℃/2V (default value) Working Temperature: -10℃-65℃ Protection Grade: IP21 Altitude: ≤3000 Meter / 9842.5ft Features: 1. Using advanced dual peak or multi peak tracking technology, when the panels are shaded or some of the panels are damaged, the IV curve will appear multiple peaks, and the controller can still accurately track the maximum power point. 2. The built in maximum power tracking algorithm can significantly improve the energy utilization efficiency of the photovoltaic system, which is about 25% higher than the traditional PWM charging efficiency. 3. The combination of various tracking algorithms can accurately track the best working point of the IV curve in a very short time. 4. MPPT tracking efficiency up to 99.9%. 5. Using advanced digital power technology, the circuit energy conversion efficiency is as high as 98%. 6. Support colloidal battery, sealed battery, open battery, lithium battery and other different types of battery charging procedures. 7. With current limiting charging mode, when the power of the panel is too large and the charging current is greater than the rated current, the controller automatically reduces the charging power to make it work at the rated charging current. · Can support capacitive load instant high current start. 9. With fault LCD display, convenient for users to determine the system fault. 10. Built in overtemperature protection mechanism. When the temperature exceeds the set value of the device, the charging current decreases linearly with the temperature, thereby reducing the temperature rise of the controller and avoiding high temperature damage of the controller. 11. With temperature compensation function, automatic adjustment of charge and discharge parameters, improve battery life. 12. Perfect electronic protection function. 13. Metal shell, better heat dissipation performance. 14. Lithium battery 0V charging function.
