The MPPT controller detects the solar panel's generated voltage in real time and tracks the highest voltage and current value (VI), allowing the system to charge the battery with maximum power output. It is the brain of photovoltaic system used in solar photovoltaic systems to coordinate the work of solar panels, batteries and loads.
Overview of MPPT
The Maximum Power Point Tracking (MPPT) system is an electrical system that enables the photovoltaic panel to output more power by adjusting the working state of the electrical module. The DC power generated by the solar panel can be effectively stored in the battery. It can effectively solve the living and industrial electricity consumption in remote areas and tourist areas that cannot be covered by conventional power grids, and does not cause environmental pollution.
The output power of a photovoltaic cell is related to the operating voltage of the MPPT controller. Only when operating at the most suitable voltage will its output power have a unique maximum.
The sunshine intensity is 1000W/m2, U=24V, I=1A; U=30V, I=0.9A; U=36V, I=0.7A; the output power is maximum under the voltage of 30.
