The full name of MPPT controller is "Maximum Power Point Tracking" solar controller is a replacement product of previous solar charge and discharge controllers. The MPPT controller detects the generated voltage of the solar panel in real time and tracks the highest voltage and current value (VI), enabling the system to charge the battery with maximum output power. Applied to the solar power generation system, it coordinates the work of solar panels, batteries and loads, and is the brain of the solar power generation system.

mppt for home user
The principle of mppt solar controller is: mppt control is generally accomplished through dc conversion circuit, the photovoltaic cell array is connected to the load through dc circuit, and the maximum power tracking device continuously detects the current and voltage changes of the photovoltaic array, and converts the dc according to its changes. The duty cycle of the pwm drive signal of the device is adjusted.

With the improvement of people's awareness of environmental protection, more and more people begin to use solar energy, which means that mmpt's related products should not only be commercial, but also small household models.
