Why all-in-one
Fewer parts. Fewer days on site.
It arrives finished
The container is pre-integrated and pre-commissioned. It is delivered ready, so deployment on site is faster.
One cabling job less
Integrated DC wiring connects battery and PCS inside the container, so there is no separate DC link to build between them on site.
Set up in five steps from your phone
One-touch boot and stop, OTA remote upgrades and a mini-app for commissioning.
Same capacity, less land
A 21 % smaller land footprint for the same capacity keeps civil works and O&M simpler.
Use cases
Where a container pays off.
Peak shaving
Cut demand peaks and the grid fees tied to them.
PV self-consumption
Shift solar output into the evening hours.
Time shifting
Charge when power is cheap, use it when itβs expensive.
Flexibility and grid services
Respond to grid signals and earn from your flexibility.
EV charging support
Charge vehicles without upgrading your grid connection.

Product vs. solution
A container is a product. A working system is a project.
The unit arrives ready. Your site doesnβt. Everything around the container is what we do.
Load and market analysis, so you build the capacity your project needs.
Integration with transformers, switchgear, metering and protection.
Application and coordination with your grid operator.
Permits and fire safety documentation, prepared for you.
Battery, grid-forming PCS, liquid cooling and DC wiring in one 20-foot unit. Factory-integrated and pre-commissioned.
Control strategy based on how your project actually earns or saves money.
Layout, foundations, installation and commissioning on your site.
Service and warranty handling in the EU.
One responsible partner for the whole system.
Choosing the right size
From a cabinet to a container.
The same all-in-one idea, in two scales. Cabinets suit smaller commercial sites, the container is built for megawatt projects.
