Do energy storage systems need to convert electric current?

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.

What are AC block energy storage systems?

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.

What are electricity storage technologies?

Electricity storage technologies are systems designed to capture energy when production is high, store it efficiently, and then release it when needed. Here’s a quick snapshot of the main types:

How do energy storage enclosures integrate with the grid?

There are two primary configurations for integrating energy storage with the grid. The first is the AC block configuration, where string inverters are internalised in each energy storage enclosure. These inverters convert DC power from the batteries to AC, allowing the energy storage enclosure to directly interface with the grid.

Why is electricity storage important?

With increasing power outages, rising energy costs, and a growing push toward renewable energy, storing electricity efficiently helps you maintain control, reduce your environmental footprint, and enjoy reliable power. Here’s a simple infographic summarizing how electricity storage technologies work and their critical role in our energy system:

How do battery energy storage systems work?

Battery energy storage systems use electrochemical processes to store and release energy. These systems are extremely adaptable, ranging from tiny home applications to huge utility-scale installations.
