12V/24V 40A MPPT Solar Charge Controller with 485 Communication Output — Max PV Input 50V, Multiple Safety Protections

Advanced MPPT solar charge controller for 12V/24V systems with a 40A charge rating and 485 communication output. Built around an industrial-grade microcontroller, it automatically manages charging tasks and saves user-set parameters even if the battery is fully drained. The unit features an easy-to-read LCD that displays status and system data, and allows mode switching and parameter configuration on the fly. Charging follows a three-stage regulation scheme — lifting charge and floating charge — to deliver fast, intelligent charging and help extend battery life. An adjustable full power-off threshold protects lithium batteries from deep discharge. Comprehensive protections include overcurrent, short circuit, reverse connection and open-circuit safeguards; all fault conditions recover automatically without harming the controller. Housed in a durable, high-strength engineering plastic enclosure that resists impact, ignition, aging and corrosion, it offers long service life and reliable safety for home, commercial and industrial installations.
