In this paper, a grid connection of single-phase PV inverter system is presented, which can deal with solar energy and performs power conditioning. To draw maximum power from the solar system we use maximum power point tracking technology for PV arrays. This MPPT technology based on the maximum power point varies with irradiation and temperature linearly. The control of a grid-connected inverter is investigated. There are two key control issues that need to be examined. The first is the control of the AC side of the converter to ensure that sinusoidal output waveforms are produced. And the output from the PV panel is controlled by the boost converter. The second key issue that needs to be examined is the current that is fed from the PV panels to the inverter. The ripple on this current must be minimized as much as possible so that the inverter can be implemented with maximum power point tracking techniques (MPPT) that will enable it to extract the maximum power that is available from the PV panels at any given time.
