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.
By using a reliable method, a cost-effective system has to be developed to integrate PV systems with the present power grid . Using next-generation semiconductor devices made of silicon carbide (SiC), efficiencies for PV inverters of over 99% are reported .
To handle high/medium voltage and/or power solar PV system MLIs would be the best choice. Two-stage inverters or single-stage inverters with medium power handling capability are best suited for string configuration. The multi-string concept seems to be more apparent if several strings are to be connected to the grid.
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).
Configuration of PV Inverters ]. Among them, the most commonly used configurations are the series or parallel and series connections. If the PV panels are attached in series with each other it is called a string, and if these are then connected parallel it forms an array. Basically, the PV modules are arranged in four ].
