Features: High current carrying capacity, to 15A of current, for solar energy systems and other applications that require high current. Low pressure drop characteristic, with lower forward pressure drop, can significantly improve energy conversion efficiency, reduce energy loss, and ensures stable systems operations. The antibackflow function effectively prevents the reverse flow of current, protects solar panel and loads from the influence of reverse current, and improves systems safety.Reverse charging protections prevents reverse flow during the charging process, ensuring safety of the battery and power equipment, and extending their service life. Wide input voltages ranges, supporting DC3V to 28V voltages input, for various solar panel and other power sources. Easy to installs, modular facilitates quick installation and connection, allowing users to easily integrate it into existing systems. High temperature resistance, construction, and materials selection can high temperature, ensuring reliability under harsh conditions. The miniaturized volumes enable it to be flexibly deployed with limited space, without taking up too much space. Good heat dissipation performances and optimized heat dissipation help reduce temperature rise and maintain the module operating at high efficiency.
