The maximum power point tracking (MPPT) optimizer is one of the common optimizers in distributed photovoltaic energy storage systems. The MPPT optimizer monitors the output power of the photovoltaic array in real time and automatically adjusts the load impedance or operating voltage to ensure that the photovoltaic module operates near the maximum power output point, which helps to improve the energy conversion efficiency of the photovoltaic array and make full use of solar energy resources.
