Everything below comes from what e-STORAGE (Canadian Solar) publishes about the KuBank 3.0 (CSI-KuBank-S-940-2h-UL / S-836-2h-IEC): 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.
