What does AC-Coupled Storage mean?

AC-coupled storage is a battery architecture where the battery connects through AC power and typically uses a battery inverter to charge and discharge.

What are the trade-offs of AC-coupled storage?

AC coupling can be useful for some retrofits because it connects to an existing AC electrical system, but solar energy may need extra DC-to-AC and AC-to-DC conversions before it is stored and used.

How it relates to Tigo

Tigo’s Microinverter Tax content uses AC-coupled storage to explain why conversion losses matter more as battery cycling increases.
