Abstract - Micro-inverter technologies are becoming increasingly popular as a choice of grid connection for small-scale photovoltaic systems. Efficiently harvesting the maximum energy from a photovoltaic system reduces the Levelized cost for solar energy, enhancing its role in combatting climate change.
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.
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).
This means that each panel has its own inverter, allowing individual panels to perform at their best, irrespective of how other panels are performing. Micro inverters offer better solar energy yields in partly shaded environments and provide detailed monitoring for each panel.
Depending upon the solar PV panel arranging, the system can be designed in different four general ways. There are centralized inverters, string inverters, multistring inverters and module based inverter configurations available as demonstrated in Fig. 2 .
As more solar systems are added to the grid, more inverters are being connected to the grid than ever before. Inverter-based generation can produce energy at any frequency and does not have the same inertial properties as steam-based generation, because there is no turbine involved.

Solar inverters use a concept called maximum power point tracking (MPPT) to get the maximum possible power from the PV array. Solar cells have a complex relationship
Types of Inverters There are basically three types of inverters based on the output. They are as follows: 1. Sine wave In this type of inverter,
