Everything below comes from what CATL publishes about the TENER Stack: 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.

Key facts
- 9 MWh in a 20-ft footprint: two half-height units, each under 36 t, stacked on site ('two in one' design)
- CATL claims 45% better volume utilisation and 50% higher projected energy density than conventional 20-ft systems
- Supports centralised and string PCS; overhead thermal management, 65 dB(A) at 1 m
- Two-hour fire resistance (triple-layer insulation), gas sensors with 10-year maintenance-free life
- Adaptable to zero-degradation or high-temperature cell variants; no shipments confirmed on catl.com as of 2026-08
What CATL does not publish for this model
These fields are empty because no public datasheet or release states them. That is information too: ask for these numbers before you shortlist.
