What is MPPT SOLAR CONTROLLER?

MPPT solar controller is designed for solar power system design; Equipment can not only efficiently transfer issued by the solar panels to recharge the battery power, but also provides a powerful control functions.

Features: The controller is characterized by intelligent adjustment of the operating voltage solar panels, solar panel always working at the VA characteristic curve of the maximum power point. More common, solar controller, solar panels for power generation increased utilization of 10-30%!

The controller uses solar panels for intelligent charging of the battery. In the solar panel power than the battery storage capacity, the control system automatically cut off the charge, thus ensuring optimum battery charging features, making full use of electricity.

As the battery can only withstand a certain degree of charge current and float voltage, over current and over-voltage charging the battery will cause serious damage. The controller battery charge grams of real-time detection voltage and charging current, and by controlling the charge current to limit the photovoltaic battery charging voltage and charging current to ensure that both the battery is full, it will not be damaged. To increase of the battery service life.
