Outcomes
What it does for your site
Peak shaving and arbitrage
Charge when power is cheap, discharge at peak times.
Demand control
Cover load peaks above your grid connection without upgrading it.
Solar self-consumption
Store surplus solar and use it after sunset.
Room to grow
Add DC-side cabinets in parallel for longer duration as your needs change.
Scale to 1 MW / 2 MWh
From one cabinet to a 2 MWh system
For larger sites, eight Cubex-261 cabinets combine into a 1 MW / 2 MWh solution. You get the same cabinet, the same service and the same controls, with eight times the capacity.

The system
Built for the outdoors
Liquid thermal management
A 50/50 glycol and water loop keeps every cell in its comfort zone, from −25 to +50 °C.
Layered fire safety
Multi-shot perfluorohexanone suppression, with water and explosion-proof venting as options.
Sealed twice
IP67 packs inside an IP55 cabinet, with C3 to C5-M anti-corrosion protection available for coastal and industrial sites.
Open interfaces
CAN, RS485 and Ethernet connect the cabinet to Cubex EMS or your own controller.
One partner
From sizing to operation, one team
We deliver Cubex-261-DC as a working system, not a box. The same team answers for it from the first sizing to long-term operation.
- 01
Size
An engineer sizes the system to your load profile, grid connection and target markets.
- 02
Build
Battery packs come from our plant in Portugal, engineered for European grid codes.
- 03
Connect
We commission the system with Cubex EMS or your own controller.
- 04
Operate
Remote monitoring, local service and after-sales from one accountable team.
