MPPT controllers, the brains of your solar system

By [email protected] | December 21, 2023

In a solar electricity system, the Maximum Power Point Tracking (MPPT) controller plays a crucial role in regulating the photovoltaic (PV) generation. The primary function of the MPPT is to maximize the power output from the solar panels by continuously adjusting the operating point of the panels to their maximum power point, which can vary based on factors like sunlight intensity and temperature.

In a scenario where there is low consumption, and the battery storage is full, the MPPT controller will adjust the operating point of the solar panels to match the energy demand. If the battery is fully charged and the power consumption is low, the MPPT controller may reduce the solar panel output to prevent overcharging the battery.

Some solar inverters and charge controllers are equipped with advanced features that allow you to configure the system to prioritize different modes of operation, such as maximizing self-consumption, feeding excess energy back to the grid, or storing surplus energy in a battery for later use. This flexibility allows the system to adapt to changing conditions and user preferences.

Keep in mind that specific system behaviour can vary depending on the design and features of the solar power system components. It’s essential to refer to the product manuals and specifications for the particular MPPT controller and inverter you are using to understand how they operate in different conditions and how they can be configured for optimal performance. Our selected brands of inverters have MPPT controllers built into the inverter and you don’t have to make a choice for external MPPTs for these inverters.
