400W MPPT Solar Controller with LED Display and Real-Time Tracking Function

This battery recharging controller can be used with solar panels( the solar panel is NOT included) to recharge most kinds of common batteries such as le-ad acid batteries, lithium batteries, lithium iron batteries. The output voltage can be adjusted between 24~85V, with multiple protections functions, and try it, it will not let you down. Features: With the LED display to see the input and output voltage and current, you can check it . The output voltage can be adjusted between 24~85V. Overheating protections function: When the internal temperature of the MPPT controller exceeds 100C, the MPPT controller will reduce the output power. If the internal temperature continues to rise to 110C, the MPPT controller will automatically turn off the output. When the internal temperature of the MPPT controller is lower than 85C, the MPPT controller will automatically resume work. Short circuit protections function: When an accidental short circuit occurs in the output of the MPPT controller, the MPPT controller automatically turns off the output, and automatically returns to normal after the short circuit is eliminated. Input undervoltage protections function: When the input direct current voltage of the MPPT controller is lower than 15V, the MPPT will shut down protectively and automatically resume work after the input voltage is normal. It has a high efficiency MPPT real-time tracking function and a high-efficiency synchronous rectification solution. It also has the IP66 waterproof and dustproof grade.
