Key facts
- Shown at EES Europe / Intersolar Europe 2026 as a 20ft modular liquid-cooled system with 'optimized energy density and minimized CAPEX'
- Cell type not stated; likely built on the 588 Ah or 661 Ah ZHIJIU cells shown at the same event (not confirmed by CALB)
- No specifications beyond nominal energy published
What CALB 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.
