Usage Tips:Features: 1.Product Information: The solar controller adopts the upgraded 3 stage PWM charging algorithm to charge the battery periodically or overdischarge equalization, and the working voltage is 12V, 24V, 48V, which effectively prevents the battery from unbalance and sulphation and prolongs the service life of the battery. 2.Function: Adopt temperature compensation, charging parameters can be adjusted automatically. Multiple load working modes, convenient for the product to be applied to different types of loads. The product provides overcharge, over discharge, overload protection and short circuit protection. 3.Advanced Design: Adopting advanced load starting method, large capacity load can also be started smoothly. The product provides dot matrix graphic LCD screen and one button human machine interface. Humanized browser and dynamic interface design ensure convenience and speed. 4.LCD Display: The solar controller is equipped with an LCD display that clearly shows status and data, making it easy for you to switch modes and configure parameters. The large screen with backlight has an LCD display, adjustable charging and discharging parameters, and a power off memory function. 5.Advantages: The operation is intuitive, has industrial grade design, the product can work properly under various harsh conditions, and adopts TVS anti light protection, which can be widely used in solar RV, home system, industrial site monitoring and many other applications.
