Features The solar controller adopts LCD display to display all parameters with rich content, intuitively understand system operation. The independent temperature sensing circuit is equipped with high-precision temperature compensation. And the exposed terminal makes wiring more convenient, in addition to the CMF series with a large metal shell. With output switch, intelligent control and easy operation, the system power supply adopts switching power supply, which reduces the static working current. There are DC12V and USB5V output with regulated switching power output, which can be used for DC lighting and mobile phone charging. Built-in energy-saving backlight board can keep better display effect and more energy saving. The use of single-chip control makes the controller intelligent, adaptable and reliable. Meanwhile, the battery controller adopts WPC control based on PWM upgrade, greatly improves system efficiency, and extends battery life.
