This powerful 20A solar charge controller automatically adapts to both 12V and 24V battery systems, providing seamless integration into various setups. Beyond basic functionality, it’s packed with features to give you a truly optimized experience.

• Advanced Charging Technology: Utilizes PWM (Pulse Width Modulation) technology to significantly boost your battery's charge acceptance and prolong its life. This smart feature can even help restore some lost battery capacity, keeping your power reliable.
• Comprehensive Protection: Equipped with a full suite of electronic safeguards, including protection against reverse current at night, over-charging, deep discharge, over-heating, over-load, short circuits, and reverse polarity. Your system and batteries are always secure.
• Versatile Compatibility: Designed for small to medium solar charging systems, handling solar panels up to 320W for 12V batteries and an impressive 640W for 24V batteries. Its wide solar input voltage range, up to 48V, ensures compatibility with many solar modules, even those typically used in on-grid systems.
• Battery Flexibility: Compatible with single gel, sealed, or flooded batteries or battery banks. The controller intelligently detects your system's voltage for hassle-free setup.
• Intuitive LCD Display & Controls: Features a clear LCD display with a multi-level menu, navigated by 4 multifunctional buttons. LED indicators offer quick status checks. A built-in temperature sensor enhances charging accuracy.
• Real-Time Performance Monitoring: Access vital data instantly, including solar panel and battery voltage, current, battery state of charge, and temperature. Stay informed about your system's health at a glance.
• Energy Statistics Counter: Track your solar performance with daily and monthly charge accumulation. This allows you to compare efficiency over different periods and make informed decisions.
• Customizable Load Work Mode: Program your load work mode with a timer for specific needs, such as setting on/off schedules for lighting or other connected devices.
• Personalized Battery Settings: Create a unique "user-defined" battery type, allowing you to set parameters specifically tailored to your battery's requirements for optimal charging and longevity.

For those seeking even deeper insights and control, this model offers cutting-edge communication capabilities:

• Remote Monitoring with MT50: Connect to a remote meter (MT50) with an LCD screen to view system performance details and manually adjust parameters and load settings from a distance.
• Wireless Control via Wi-Fi: Add a Wi-Fi module to create a network, enabling you to monitor and adjust charging parameters and controller settings conveniently through the Solar Station Monitor mobile app (compatible with Android phones and tablets).
• PC Connectivity: Use an RJ45 to USB cable to link the controller directly to your PC or laptop. The Solar Station computer program (compatible with Windows PCs) provides detailed monitoring and adjustment options.

Through any of these communication methods, you gain comprehensive access to various charging parameters like voltage, current (for both solar panel and load), battery state of charge, accumulated charge and discharge energy, minimum/maximum voltage, and more. You can also fine-tune battery type and capacity, set charging voltages for different stages, define stage durations, create user-defined battery profiles, and personalize 'load' settings like timers for specific devices.

To further enhance charging precision, the controller includes terminals for an optional remote temperature sensor. This sensor can be attached directly to your battery, providing highly accurate temperature measurements for truly optimized charging performance.
