For factories, industrial parks and commercial facilities, energy storage requirements often change as production capacity, PV installations and power loads evolve. A system must meet current needs while also allowing for future expansion without adding complexity to safety, operation and maintenance, or service.

Cube 261-Plus is built on a standardized platform. It uses an AC-coupled all-in-one cabinet as the foundation, with DC battery expansion cabinets added as required. Projects can start with a single-cabinet 2-hour system and expand gradually based on the application.

01 | Scale to Match Each Application

The Cube 261-Plus AC-coupled all-in-one cabinet is rated at 125 kW and 261.2 kWh, with a single cabinet providing a 2-hour system. At the initial stage, the system can be configured according to current load profiles and energy requirements. If only a longer storage duration is required, one or more Cube 261DC-Plus battery expansion cabinets, each rated at 261.2 kWh, can be added to form 4-, 6-, or 8-hour systems. If both power and energy capacity need to increase later, additional Cube 261-Plus all-in-one cabinets can be connected in parallel based on changes in production capacity, PV system size. The system supports unlimited parallel expansion. Since all configurations share the same platform, the existing technical architecture can be retained after expansion, while O&M training and spare parts management remain simple.

02 | Multi-Layer Safety from Cell to Cabinet

Cube 261-Plus uses 314Ah lithium iron phosphate cells and an intelligent liquid cooling system that keeps the temperature difference between cells within 3°C, providing a more balanced thermal environment for stable battery operation. The system is equipped with PACK-level and cabinet-level aerosol fire suppression, IP54 protection and C4 corrosion resistance. These safety measures cover the cell, PACK and cabinet levels, providing long-term effective protection across different system configurations.

03 | Remote O&M with Clear System Visibility

Cube 261-Plus supports cloud-based monitoring, remote diagnostics, OTA upgrades and product traceability. O&M teams can monitor system status remotely and use online diagnostics to identify issues, reducing unnecessary on-site troubleshooting. Charging and discharging strategies can also be optimized according to load profiles, time-of-use electricity rates and PV output, helping the system better match actual energy requirements. The product comes with a 5-year warranty and a system design life of 15 years, supporting long-term operation and return on investment.

There is no single configuration that suits every C&I energy storage project. By combining the AC-coupled all-in-one cabinet with DC battery expansion cabinets, Cube 261-Plus provides a clear expansion path from a single-cabinet 2-hour system to configurations of up to 8 hours.
