Today this is state of the art that these systems have a power conversion system (PCS) for battery storage integrated. This application note outlines the most relevant power topology considerations for designing power stages commonly used in Solar Inverters and Energy Storage Systems (ESS). Figure 2-1.
In this topology, the integration of inverter and PV module is carried out in a single electrical device. It is a “plug and play” device and does not require expertise for its installation. The mismatch losses of the PV modules are eliminated in this topology . It has a modular design and can be easily expanded.
Islanding is the process in which the PV system continues to supply power to the local load even though the power grid is cutoff . A safety feature is to detect islanding condition and disable PV inverters to get rid of the hazardous conditions. The function of inverter is commonly referred to as the anti-islanding.
In addition to conventional full bridge switches S 6, S 5, S 4, and S 3, bidirectional switches S 1 and S 2 along with the diodes D 1 and D 2 are added. This allows the proper control of current flowing to and from the midpoint of DC bus. With this topology, the minimum size of the inverter for a transformer-less PV system is approximately 1.5 kW.
Another classification of the inverters, as per the existing literature, is made based on the existence or absence of the transformer. In other words, this classification can also have the single or multiple power stages but the main categorization in this case is based on the transformer.
