This document examines DC-Coupled and AC-Coupled PV and energy storage solutions and provides best practices for their deployment. In a PV system with AC-Coupled storage, the PV array and the battery storage system each have their own inverter, with the two tied together on the AC side.
The term coupling refers to point a point of connection. The majority of PV systems consist of two distinct electrical systems, DC and AC. When these systems employ battery backup function, there are two points of connection that can be made with the output of the solar array.
The DC-coupling solar-plus-storage design means that an energy storage system connects to a solar system via DC side (as shown in Figure 2). In this solution, a pre-assembled e n ergy storage interface of a PV inverter will be necessary. Inverter suppliers represented by Sungrow have launched more product portfolios
