Wide range of applications: suitable for solar power generation systems, smart homes, solar chargers, solar ventilation systems, solar light boxes, solar billboards, solar warning lights, and more. Lightcontrol and timecontrol: this controller supports lightcontrolled discharge and programmable timebased discharge, enabling operation based on sunlight and set timing. Multiple protections with automatic restoration: builtin overcurrent protection, shortcircuit protection, reverseconnection protection, and opencircuit protection; all protections reset automatically without damaging the controller. Efficient intelligent charging and battery life extension: using the controller enables fast, intelligent charging and helps prolong the service life of the battery. Use scenarios: In smart homes and solar lighting setups, the controller manages charging and lighting for solarpowered devices and systems. For outdoor signage and safety, such as solar billboards and solar warning lights, the controller ensures reliable charging and protection. In offgrid or remote locations, it supports solar ventilation systems and solar charging for cabins, gardens, or other solar power generation applications.
