The Solarmax 50A Solar Charger Controller with Dual USB is a high-capacity, precision-engineered controller designed to meet the energy demands of large off-grid solar systems. Supporting up to 50A of charging current, it’s the perfect choice for powering substantial solar arrays in off-grid homes, cabins, RVs, agricultural setups, and even light commercial applications.

Built with advanced PWM (Pulse Width Modulation) charging technology, the Solarmax 50A controller maximizes solar energy conversion while extending the lifespan of your battery bank. It automatically detects whether your system is 12V or 24V, making installation a breeze and ensuring optimal performance.

A large, intuitive LCD display provides real-time monitoring of essential system metrics, including battery voltage, charging current, load status, and system health—giving you full visibility and control over your solar setup.

The controller features dual 5V USB ports, allowing you to directly charge your smartphones, tablets, and other USB devices, eliminating the need for separate chargers and improving system versatility.

With comprehensive built-in protections—overcharge, over-discharge, overload, short-circuit, and reverse polarity—the Solarmax 50A controller ensures the safety and longevity of your entire solar energy system. Housed in a durable, compact casing, it’s designed to handle tough environments and continuous operation, making it an essential part of any reliable, large-capacity solar system.
