What is a photovoltaic inverter?
One of the key components of the photovoltaic (PV) system is inverters due to their function as being an operative interface between PV and the utility grid or residential application. In addition, they can be employed as power quality conditioners at the point of common coupling (PCC).
What types of inverters are used in photovoltaic applications?
This article introduces the architecture and types of inverters used in photovoltaic applications. Inverters used in photovoltaic applications are historically divided into two main categories: Standalone inverters are for the applications where the PV plant is not connected to the main energy distribution network.
Do PV modules have inverters?
Therefore, it was considered desirable to design systems that have inverters inside the PV modules. This type of design was initiated in early 90's under the name of OK4 (Oldenkamp and DeJong, 1998) and is also termed as Micro-Inverter (MI), Module Integrated Converters (MIC) or AC module (Dumais, 2010, Kjaer, 2005, Li and Wolfs, 2006).
How to pair a solar inverter with a PV plant?
In order to couple a solar inverter with a PV plant, it’s important to check that a few parameters match among them. Once the photovoltaic string is designed, it’s possible to calculate the maximum open-circuit voltage (Voc,MAX) on the DC side (according to the IEC standard).
How photovoltaic (PV) is used in distributed generation system?
The application of Photovoltaic (PV) in the distributed generation system is acquiring more consideration with the developments in power electronics technology and global environmental concerns. Solar PV is playing a key role in consuming the solar energy for the generation of electric power.
