What does AC-Coupled Battery mean?
An AC-coupled battery connects to the AC side of a solar system and uses its own conversion equipment to charge and discharge.
What should installers verify about AC-Coupled Battery in a solar-plus-storage design?
AC- and DC-coupled architectures describe where solar, storage, and conversion equipment connect electrically. The architecture affects conversion steps, equipment count, service access, backup design, and how excess PV energy can be routed to loads, batteries, or the grid.
Practical design considerations
- Separate energy capacity, power output, backup duration, and load priority; they are related but not interchangeable.
