Inquire NowDescription
The 40A 12V/24V USB Output MPPT Solar Charge Controller is a state-of-the-art device designed to maximize the efficiency of solar energy systems. Utilizing advanced MPPT (Maximum Power Point Tracking) technology, it intelligently adjusts the working point of the solar array to ensure the highest possible power output, even under changing external conditions. This feature significantly enhances the efficiency of solar panels, improving their output by 5% to 30% compared to traditional PWM controllers, depending on solar panel attributes and environmental factors.
This controller is equipped to handle both 12V and 24V systems automatically and features a peak conversion efficiency of over 98%, making it an ideal choice for off-grid solar applications. Additionally, the multi-stage charging modes, including MPPT, Absorption, Float, and Equalization, cater to various battery types, ensuring optimal battery health and longevity. With a USB output of 5V at 1A, it also allows for the charging of USB devices, adding versatility to your solar setup.
