MPPT Solar Charge Controller
MPPT solar charge controller is Multi-stage Maximum Power Point Tracking (MPPT) photovoltaic battery charge controller with our own technology. It’s main topology adopts in Buck conversion circuit, and uses MCU to adjust the solar panels working point intelligently in order to make the solar panels output is maximum power.
Product Introduction
The main topology of the MPPT solar charge controller adopts buck conversion circuit, and uses the microcontroller to intelligently adjust the working point of the solar panel, so that the solar panel can output the maximum power. Compared with PWM controller, MPPT can increase the output power of solar panel by 5% - 30%. The proportion of output power increase is affected by solar panel characteristics, humidity, light intensity and other factors. The controller is wall mounted. It also uses wiring terminals to make the wiring area larger and the wiring loss smaller.
Features
The MPPT solar charge controller adopts advanced MPPT tracking, and the efficiency can reach 99%. At the same time, it also uses LCD to display photovoltaic data and graph to simulate the power generation process. It also supports a wide photovoltaic input voltage for easy system configuration. The battery has intelligent management function, which can extend the battery life. It also has an optional RS485 communication port to facilitate user integrated management.
