LONGi — from commercial storage to utility-scale containers

In the Speichercampus portfolio, LONGi covers the broadest range: the OmniCube cabinet systems for commerce and industry, PotisMobile for mobile deployments, the PotisCabinet as a control and coupling unit, and the PotisBank series for projects in the megawatt-hour range.

The product lines

  • OmniCube A215 — the featured product: 215 kWh, 105 kW, STS, MPPT, EMS and Modbus in one system
  • OmniCube L233 — the liquid-cooled alternative in the cabinet class
  • PotisMobile L652 — mobile power supply in a 10 ft container
  • PotisCabinet D9 — AC control cabinet for hybrid and island systems
  • PotisBank L3.7 / L5.0 / L6.25 — utility-scale containers for grid-scale projects

The Speichercampus perspective

The LONGi systems are not run as a catalogue but classified by application: from a single commercial project with the A215 to a storage park built on PotisBank. The project review decides which line carries at the site.
