Technical FAQs 4

What is DC-coupled and AC-coupled PV & energy storage?

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.

What is a DC-coupled Solar System?

DC-Coupled system ties the PV array and battery storage system together on the DC-side of the inverter, requiring all assets to be appropriately and similarly sized in order for optimized energy storage and power flow. Mid to large-scale solar is a non-reversible trend in the energy mix of the U.S. and world.

What is a PV system with AC-coupled storage?

In a PV system with AC-Coupled storage, the PV array and the battery storage system each have their own inverter, with the two systems tied together on the AC side. The two systems are thus electrically separated, allowing a customer to size each separately.

What is an energy storage system standard?

This is a system standard, where an energy storage system consists of the energy storage mechanism, power conversion equipment and balance of plant equipment. This standard evaluates the compatibility and safety of these various components integrated into a system.
