Abstract

Although the photovoltaic (PV) system plays an important role to meet our needs of an electrical energy, it represents a direct current (DC) source. So, it is not suitable for alternating current (AC) residential loads. This paper proposes a design and practical implementation for a smart single phase low cost inverter, which could be an effective solution to reduce the overall cost of the PV system and supply AC loads. The low cost inverter is achieved by designing low cost control and power circuits. In the power circuit, PV modules operate near the maximum power point (MPP) and supply AC load requirements through the inverter switches. The control circuit uses a microcontroller which provides a smart system for interaction with the user and remote control and monitoring, in addition to use a digital control to maintain the AC output voltage at the required value.
