AI Customer ServiceThe battery voltage depends upon the system power level. Lower power single phase systems commonly use 48-V battery, while higher power three phase systems use 400-V battery. Intermediate battery voltages are used infrequently. Systems with higher power range of string inverters could use 800-V battery for storage.
A lot of research and development is occurring in power conversion associated with solar string inverters. The aim is towards preserving the energy harvested by increasing the efficiency of power conversion stages and by storing the energy in distributed storage batteries.
Systems with higher power range of string inverters could use 800-V battery for storage. The common topologies for the bidirectional DC/DC power stage are the CLLLC converter and the Dual Active Bridge (DAB) in isolated configuration. In non-isolated configurations, the synchronous boost converter can be used as a bidirectional power stage.
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 functions of translating the string voltage to a level suitable for the inverter (typically 400 V for single phase and 800 V for three phase) and Maximum Power Point Tracking (MPPT).
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 Active clamped current-fed bridge converter shown in Figure 4-6 is another bidirectional power conversion topology commonly used in low voltage (48 V and lower) battery storage systems. Some lower power systems use a push-pull power stage on the battery side instead of the full bridge.
