Features With output switch, intelligent control and easy operation, the system power supply uses a switching power supply that reduces the static working current. Adopt LCD to display all parameters, rich in content, solar controller can intuitively understand system operation. Exposed clamp facilitates wiring, additionally CMF series with large metal housing. DC12V and USB5V output with switching power supply regulated output can be used for DC lighting and charging mobile phones. Independent temperature detection circuit with high accuracy temperature compensation. The use of a single-chip controller makes the control intelligent, adaptable and reliable. With the built-in energy-saving backlight board, the controller supports a better display effect and more energy saving. The battery controller adopts WPC control based on a PWM upgrade, greatly improves system efficiency and extends battery life.
