This 50A MPPT solar charge controller offers high efficiency with advanced MPPT technology, achieving up to 99% tracking accuracy for optimal energy conversion. Designed for 12-Volt and 24-Volt systems, it automatically adapts once the battery is connected, ensuring seamless operation. The LCD display provides real-time monitoring of charging current, discharge current, and power generation for precise energy management. Dual USB ports allow convenient device charging, while an industrial-grade master chip ensures 16AD sampling accuracy for reliable performance. Built-in protections include overvoltage, short circuit, overload, overcharge, and over-discharge safeguards, enhancing system durability. Automatic MPPT tracking and bidirectional focusing improve charging efficiency with continuous detection during operation. For proper installation, the battery must be connected before the solar panel to ensure correct functionality. Ideal for off-grid applications, RVs, boats, and solar power systems, this controller maximizes energy use while ensuring long-term reliability for solar charging needs.
