In this AC coupling architecture, two inverters work in tandem: a solar inverter converts DC power from PV panels to AC electricity for immediate use, while a bidirectional battery inverter manages the AC-coupled battery by converting excess AC power back to DC for storage, and then. . In this AC coupling architecture, two inverters work in tandem: a solar inverter converts DC power from PV panels to AC electricity for immediate use, while a bidirectional battery inverter manages the AC-coupled battery by converting excess AC power back to DC for storage, and then. . However, the interleaved PWM causes a circulating current between the inverters, which in turn causes additional losses. A model describing the dynamics of the circulating current is presented in this study which shows that the circulating current depends on the common-mode voltage. How does a PV. . An inverter is one of the most important pieces of equipment in a solar energy system. AC coupled solutions include microinverters, string inverters, other battery-based inverters, and possibly even another Sol-Ark nverter.
