Product Detail
48V-50A PWM Solar charge controller Applying with various types of batteries Multiple protect functions

No .1  General  Description 

The solar charge controller is the intelligent power with integration of controlling . It can store electrical power generated by the solar panels into the storage battery.

The controller not only has perfect appearance, LCD display and convenient operation, but also has over-charge protection, over-voltage  protection, over-hot protection, under-voltage protection, pole-confusion protection for storage battery and automatic dump-load function. The controller is adopted the constant voltage charging mode-PWM, and it has high reliable and safe operation, high efficiency, long service life functions. What’s more, it adopts the American origin Micro-controller as a control core component with reliable. And the power parts of an apparatus adopt the import component, too.
