For three and one phase grid connected PV systems various inverter topologies are used such as central, string, multi-string inverter, and micro-inverter base on their arrangement or construction of PV modules interface with grid and inverter as shown in fig 2. 3.1. Grid Connected Centralized Inverter
Inverter is essential component in grid connected PV systems. This review focus on the standards of inverter for grid connected PV system, several inverter topologies for connecting PV panels to the three phase or single phase grid with their advantages and limitations.
There are three main inverter topologies according to their architecture are central inverter, string/multi-string inverter and module integrated microinverter. Central inverter topologies is mostly preferred for large scale generation and it has centralized inverter and common MPPT for PV array (series-parallel connection of PV modules).
This paper discusses the inverter standards of PV systems that must be fulfill by the inverter used in grid connected PV systems focusing on THD (<5%), DC current injection, Anti- islanding detection standards. It also discusses the various inverter topologies used in grid connected PV system and their converter topologies.
