PWM Solar Charge Controller 12V/24V 10-40A

Keep your off-grid solar system running efficiently with this PWM Solar Charge Controller, designed to regulate the charge flowing from your solar panels into a 12V or 24V lead-acid battery bank. Available in 10A, 20A, 30A, and 40A current ratings, it automatically detects your battery voltage and applies a multi-stage charging process to prevent overcharging while protecting your battery from deep discharge. This makes it an essential component for home solar setups, cabins, caravans, remote monitoring stations, and DIY renewable energy projects.

Built around an industrial-grade microcontroller, the unit features an LCD display for real-time monitoring of voltage, current, and system status, along with adjustable parameters for float charge, load reconnect, and discharge protection thresholds. Built-in safeguards include short-circuit, open-circuit, reverse-polarity, and overload protection, along with dual MOSFET reverse-current protection to minimize heat buildup and maximize efficiency. Many models also include dual USB outputs, letting you charge phones and other small devices directly from the controller.

Compact and straightforward to wire, this controller suits sealed, gel, and flooded lead-acid batteries. Select the current rating that matches your solar array’s output for a safe, reliable, and long-lasting charging setup. Please verify panel wattage compatibility against your chosen model before installation.
