Early on the ESS industry had 40-foot containers; later this evolved to ‘cubeʼ products in 10-foot sizes, but the industry has now coalesced around a single size: the 20-foot shipping container

Driven by safety concerns and ease of shipping, each container has gradually added more and more energy. Increasing energy density of the cells, larger format cells, and more efficient design have all contributed to this convergence. While some designs use traditional corrugated shipping containers, others have opted for proprietary enclosures. Nearly all enclosures feature integral liquid cooling, although some offer air-cooling as an alternative. The industry is still divided among products that feature integral PCS units in the enclosure AC Block product) or those that require an external PCS DC Block products). Notable leaders in AC Block are Tesla, Sungrow, and Wartsila.

* DC rated capacity for each project is as reported by manufacturer. Products enclosures are based on 20-foot containers. All products are DC block, with the exception of the PowerTitan 2.0 and Quantum3.
