PowerCube™ components
Intelligent grid storage system in a container.
The PowerCube™ 10C250K container contains:
- 30 to 40 battery modules, each containing 16 high capacity LFP cells in series and a module Controller (BMU).
- arranged in two strings in parallel, each with 15 to 20 modules in series and a String Controller (CMU).
- Temperature control system with air cooling or heating for each string.
- 2 customized 400Vac Power Conversion Systems (PCS) to integrate easily in commercial or solar sites.
- Complete firefighting system.
- Auxiliary power system.
- Storage Module Controller (GPC) to control and monitor all modules and strings and monitor safety and store online statistical data.
- Energy Management Controller (EMC) to control inverters, switches, other solar inverters and provide standard interfaces to energy management and trading platforms.
- Backup 4G or satellite connection.

2 Power conversion Units, auxiliary power.
Independent Inverters
Independent PCS for each battery stack allows variable DC voltage profiles to maintain optimum charge and discharge status of each battery stack over time. Can prevent capacity loss caused by cross current and increase lifetime discharge capacity.
Over time, charge and discharge performance of parallel battery stacks will vary due to divergences in the internal resistance of the cells. Tests have shown that:
- the capacity loss increases by up to 2 % per year when eight racks are connected in parallel compared to non-parallel connections.
- when two battery stacks are connected in parallel and the SOC differs by 8%, after a complete charge-discharge cycle, the total discharge capacity of the energy storage system with independent PCS inverters (or floating DC-DC controllers) is increased by up to 7%.
Battery stacks with new and old battery packs can be combined, allowing them to be replaced and extended. Independent stack inverters also add to the ESS reliability and availability as stacks can operate fully independently.
3 level Control Architecture
- Battery pack monitoring unit (BMU) cell balancing and monitoring ensures optimum cycle life and safety for each cell in a module.
- String Controller (CMU) in each battery stack for independent stack monitoring.
- Intelligent Storage System Controller (SMC) for cabinet monitoring and safety with separate Energy Management Controller (EMC) to monitor and control PCS for energy trading or Frequency Reserve applications.

Distributed Energy Resources
for greener and revenue generating micro grids
To accelerate the renewable energy transition, we provide decentralized micro and medium sized battery storage power solutions. This enables faster deployment, lower national infrastructure investments and better resiliency. Industrial, public services or residential facilities can have control of their power supply security and cooperate with the regional or national grid. Small and medium sized businesses can control their energy costs, secure their supply and protect themselves from costly power blackouts, while meeting their carbon footprint reduction goals or requirements.
We can also facilitate the pooling and aggregation of small energy storage blocks to participate in large balancing markets across Northern Europe.
