Product overview
MPPT series controller is our company independent research and development solar charge controller with the function of MPPT Controller is adopt buck transform circuit and using MCU working intelligent adjustment for solar battery pack to make the solar cell pack output maximum power in the current environment. When environmental conditions change, solar cell pack deviate the maximum power point
MCU of controller based on MPPT algorithm adjust the working point of solar cell pack and make solar cell pack return to maximum power point.
Main features
+ Intelligent maximum power point tracking technology;
+ Built-in high-performance DSP controller;
+ Automatic battery voltage detection, and battery performance optimization through three-stage charge;
+ Display of detailed information by a multi-functional LCD;
+ Reversed polarity protection for the solar panel and the batteries;
+ Overcharge protection and overload protection.
