Intelligent chip: industrial-grade main control chip, industrial-grade intelligent main control chip, 16-level AD sampling accuracy, real-time accurate display of temperature, charging current and discharge current.Automatic focus tracking charging: high charging efficiency, continuous induction while charging, two-way focus tracking.The MPPT tracking efficiency can reach 99.9%.The charging efficiency is 15%-20% higher than that of the general controller, and the circuit power conversion efficiency reaches 98%.Intelligent large-screen main console: large-screen LCD display, adjustable charging and discharging parameters, adjustable ultra-wide charging, as long as you understand the characteristics of the battery and set the corresponding charging parameters, you can charge the battery arbitrarily, turn offpower output, adjustable, more practical.Current-limited charging mode: When the panel power is too large and the charging current is higher than the rated current, the controller will automatically reduce the charging efficiency and work at the rated charging current.Two-way anti-mosquito tube anti-reverse circuit, high-power charging mode, extremely low heat.A variety of protections: built-in overheating, overcurrent, short circuit, open circuit protection, reverse connection protection, the controller will automatically recover after troubleshooting without damaging the equipment.Three-stage charging management to effectively protect the battery.Contents: 1 solar controller Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
