Output interfaces include PD, QC, FCP, PE, SFCP and other protocol outputs, with MPPT power point tracking and multiple protection circuits for efficient, stable and safe operation. Suitable for solar power generation, lowpower Internet of Things, and other green projects. Supports multiple charging methods such as solar panels and TypeC power adapter. Power management module suitable for 6V to 24V solar panels; supports charging of 3.7V rechargeable and dischargeable batteries through solar panels or TypeC interface; provides a 5V/3A regulated output. MPPT power point tracking function to greatly improve solar energy conversion efficiency. Use case 1: Remote IoT or environmental monitoring devices powered by solar energy in offgrid locations, where reliable charging and protection are essential. Use case 2: Portable solar charging solutions for small devices or as part of a compact solar generator; TypeC and 5V/3A outputs enable charging of and power delivery to mobile devices and microcontrollers. Use case 3: Green projects such as solarpowered monitoring stations or offgrid systems requiring compatibility with 6V–24V panels and Li 3.7V batteries, delivering efficient energy management and safe operation.
