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.
This power stage is unique to the storage ready inverters. The boost converter (interleaved for higher power levels) is the preferred topology for non-isolated configuration, while the phase-shifted full bridge, dual active bridge, LLC and CLLLC are used in isolated configuration.
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 storing it in distributed storage batteries and increasing the efficiency of power conversion stages.
Recent improvements in semiconductor technology is allowing for string inverters with high power density (from 10s of kW to 100s of kW). Solar string inverters are used to convert the DC power output from a string of solar panels to a usable AC power.
As PV solar installations continues to grow rapidly over the last decade, the need for solar inverter with high efficiency, improved power density and higher power handling capabilities continues to scale up.
String inverters are commonly used in residential and commercial installations. They are modular and easy to service, making them a popular alternative to central inverters. Recent improvements in semiconductor technology have allowed for string inverters with high power density, ranging from 10s of kW to 100s of kW.
