400W Step-Up MPPT Real-Time Tracking Function LED Display Solar Supply Battery Recharging Controller 24-85V

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.
