A Cabinet BESS is a battery energy storage system installed inside a compact electrical cabinet. It can integrate battery modules, BMS, PCS, EMS, power distribution, thermal management and fire protection into one coordinated outdoor system.

GeePower standard Cabinet BESS configurations include:

• 20kW / 51.2kWh
• 50kW / 107.4kWh
• 100kW / 215.04kWh

The appropriate model depends on the load profile, required storage duration, grid connection, solar capacity and project operating strategy.

Yes. Multiple cabinets can be configured as a larger distributed energy storage system.

The recommended number of cabinets depends on total power, energy capacity, site layout, cable routing, communications, protection design and the customer’s expansion plan.

Yes. A Cabinet BESS can be configured to store energy from solar PV or the utility grid and discharge it according to the selected operating strategy.

Common modes include solar self-consumption, peak shaving, load shifting, scheduled charging and backup for selected loads. The available modes depend on the PCS, EMS and overall electrical design. 

It can provide backup power when the system is designed with the required switching, PCS capability and critical-load connection.

Backup duration depends on available battery capacity, load demand and the required depth of discharge. These requirements should be confirmed during project design.

Cabinet BESS is often suitable for projects below 300kWh, sites with limited access and customers planning phased expansion.

Containerized BESS is generally more suitable for MWh-scale centralized projects. Projects between 500kWh and 1MWh should be evaluated individually rather than selected by capacity alone.

Yes, subject to the selected PCS, site design and local DNO requirements. For grid-parallel projects in Great Britain, we review the applicable G99 connection route, protection requirements and available technical documentation before confirming the configuration.

G100 requirements can also be considered where export limitation is required. Final connection approval remains specific to the installation and local DNO.

Yes. For grid-parallel projects, the selected PCS and protection design are reviewed against applicable NRS 097-2-1 and Eskom or municipal requirements. Available inverter type-test documentation is confirmed before the final configuration is agreed.

Off-grid, backup and zero-export systems are evaluated separately according to the project location and operating requirements.

Our production lead time is approximately 30 to 40 days after order confirmation. We offer expedited production planning for urgent projects, subject to current capacity.

We will deliver a tailored configuration proposal and formal quotation within 3 business days after we receive your complete project specifications (capacity, voltage, and application scenarios)

We back our systems with solid guarantees. We provide a 5-year warranty for the battery cells (the core component) and a comprehensive 2-year warranty for the entire cabinet system.

We offer remote online guidance for system commissioning and troubleshooting. Furthermore, we can dispatch our senior engineers to your site for on-site technical support and training if your project conditions require it.

We can provide relevant CE, UKCA, UN38.3, MSDS, G99-related compliance documentation. However, not every configuration carries the same set of documents, as requirements may depend on the battery system, PCS and overall system design. Please confirm the required certifications and grid-connection requirements with our team before finalizing the configuration.

Flexible for both trials and bulk orders. We do not enforce a strict MOQ for our Cabinet BESS.

Customization is our strength. Absolutely. We provide comprehensive OEM services and support full project-specific configurations.
