This is a practical solar system controller. It has a built-in industrial micro controller chip and fully 3-stage PWM charge management. The build-in short-circuit protections and over-load protections is more safe for using. It can be applied to solar road lamp, solar pest killing lamp, solar plate installation and so on.
Features:
Adopt industrial micro controller chip.
Large LCD screen for display.
Auto memory function.
Fully 3-stage PWM charge management.
Dual USB charge port.
Build-in short-circuit protections, open-circuit protections, reverse protections and over-load protections.
Dual mosfet reverse current protections and low heat productions.
