Solar Charge Controller for managing battery charging to help extend battery life by preventing overcharging. Designed for use with 12V or 24V battery systems. The controller automatically detects system voltage (12V/24V). Built-in industrial microcontroller. Features state of charge (SOC) indication to display battery condition. Utilizes Pulse Width Modulation (PWM) charging technology with four-stage charging process. Includes protection against short circuit, reverse current, reverse polarity, and overcharge. Well-constructed with reliable performance. User-friendly design. Durable for long service life.
