In the solar photovoltaic power generation system, the most humble is the solar controller. However, solar controller is the brain of a photovoltaic system, it also coordinate with solar panels, battery and load at the same time.
And now in the civilian market generic solar controller has two types, PWM and the MPPT! MPPT controller
means Maximum Power Point Tracking controller, is an upgraded version of PWM controller
.The output power of solar panels is associated with the working voltage of the MPPT controller, only work in the most appropriate voltages, its output will have a maximum value of only.
As important as computer CPU, choosing MPPT solar controller can improve the efficiency 30% at least of the whole system. View more
