Everything below comes from what Envision Energy publishes about the 5.03 MWh Liquid-Cooled DC Container (ENS-LC): the datasheet, the product page and press releases. Where a figure is not published, the field says so — we do not estimate.
Variants
Energy figures are nominal (beginning of life) as published by the manufacturer. One model, several duration options — the same enclosure with different power ratings.
