AC blocks also provide higher availability, which is defined as the percentage of time an energy storage system is online and operating at its designed capacity. If a DC block’s central inverter fails, a larger section of the energy storage system needs to be shut down to replace it.
Innovations in string inverter technology and software controls are giving rise to AC block energy storage systems. While DC blocks will continue to have their place in the energy storage market, AC blocks provide distinct advantages such as granular control, higher availability and shorter project development timelines.
Energy storage systems require the ability to convert electric current because the electric grid operates on Alternating Current (AC), while batteries store energy in Direct Current (DC). There are two primary configurations for integrating energy storage with the grid.
Article 706.2 of the 2017 National Electrical Code (NEC) defines an energy storage system as: “ One or more components assembled together capable of storing energy for use at a future time. ESS (s) can include but is not limited to batteries, capacitors, and kinetic energy devices (e.g., flywheels and compressed air).
With this technology now available, AC and DC block configurations are both competitive options for energy storage sites. Each offer distinct advantages that can be leveraged depending on the requirements and scope of your project.
The ac-dc distinction has major system design implications. In an ac-coupled system, power from the PV modules is converted to ac prior to connecting to the ESS. In other words, the output from the PV modules is fed through an interactive inverter before it reaches the ESS.
