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.
Power Topology Considerations for Solar String Inverters and Energy Storage Systems (Rev. A) As PV solar installations continue to grow rapidly over the last decade, the need for solar inverters with high efficiency, improved power density and higher power handling capabilities continue to increase.
A more detailed block diagram of Solar String inverter is available on TI's String inverter applications page. The MPPT DC/DC power stage performs the function of translating multiples of MPPT voltage of a panel (depending on the number of panels in a string) to a stable voltage level suitable for the inverter or DC/DC stage for battery input.
With the additional possibility of energy storage via batteries, hybrid string inverters provide a good outlet to maximize the power utilization of the string input, and also provide an alternate pathway to supply the grid during night or low irradiation scenarios.
The battery voltage depends upon the system power level. Lower power single phase systems commonly use 48V battery, while higher power three phase systems use 400V battery. Systems with even higher power range of string inverters could use 800V battery for storage. This may vary depending on the application and use case.
In boost mode, since this converter supplies the inverter through the DC-link, the discharge power is limited to 4.6kW, the limitation being the maximum power rating of the inverter stage. Depending on the battery voltage, this value can go up to 30A.

This solution allows sharing the inverters between the PV module and BESS (in this case the inverter shall be able to operate in all the 4 quadrants of P-Q diagram) and all the AC side of the plant will be in sharing. This choice is quite common for residential applications, or in the case of a small plant (kW). In the case of a large-scale plant, the BESS will be distributed …
