Abstract :

This paper presents the design and implementation of a microprocessor-based inverter for maximum power point tracker for photovoltaic applications. Photovoltaic module is characterized with unstable output power, which varies with different environmental conditions. . The inverter is controlled by a microprocessor via the MPPT program. The microprocessor-based inverter with maximum power point tracker is made up of a PV module, Analog-to-Digital converter (ADC), microcontroller, frequency divider, buffer inverter, power inverter circuit and power regulator. A fairly constant output voltage (Vo) and current (Io) was realized throughout the daytime as presented in the results.
