The efficiency of a DC-coupled system compared to an AC-coupled system in solar energy setups depends on several factors, but both systems have their own advantages and considerations.
In a DC-coupled system, where solar panels are directly connected to batteries, there may be slightly fewer conversion steps, potentially reducing energy losses. However, this simplicity also means that there might be limitations in terms of system flexibility.
AC-coupled systems use an inverter to convert DC power from solar panels to AC for use in the home or grid. This AC power can then be converted back to DC for charging batteries if an energy storage system is part of the setup. While this introduces more conversion steps, it provides flexibility in choosing different components, especially for retrofitting existing solar installations.
