The Felicity 100A MPPT Solar Charge Controller is a high-efficiency device designed for 12V, 24V, or 48V off-grid solar systems, featuring intelligent Maximum Power Point Tracking (MPPT) technology that boosts charging efficiency by up to 30% compared to traditional PWM controllers. With a maximum charging current of 100A and support for up to 5500W of solar input at 48V, it employs three-stage charging to optimize battery performance and longevity, including automatic voltage detection and a lithium battery wake-up function. Its comprehensive LCD display provides real-time monitoring and fault codes, while built-in protections against overcharge, over-temperature, and reverse polarity ensure reliable operation in demanding environments.
