Battery energy storage systems — BESS
Cabinet and container battery storage for industrial sites, commercial buildings and larger energy installations. Supply combines batteries, power conversion, controls and connection to the local electrical network.
Operating context
The whole application matters.
BESS helps align electricity generation and consumption over time, manage demand peaks and use local solar production. Design starts with the site's operating profile and required function: power, usable energy and operating strategy are defined separately. The range covers compact outdoor cabinets, modular assemblies and container systems with power conversion and controls. Larger installations include interfaces to transformers, switchgear and the connection point. Backup operation is designed around the selected electrical configuration and the needs of critical loads.
Scope of the solution
- Battery modules, cabinets and containers with BMS, power conversion systems and auxiliaries.
- Energy management, local operation, operating records and remote monitoring.
- Switchgear, cabling, metering and interfaces to transformers and the grid connection.
- Integration with solar generation, site loads and EV charging according to agreed priorities.
- Installation coordination, commissioning, diagnostics and maintenance of the supplied assembly.
Engineering priorities
From operating need to design.
01Power, energy and operating purpose
The generation and demand profile determines storage size and the charging strategy. Design considers operating reserve, expected cycling, system auxiliary consumption and future expansion. The aim is to match the assembly to site requirements and available connection capacity.
02Batteries, PCS, BMS and EMS
The power conversion system, PCS, transfers energy between the battery and the AC network. The BMS monitors cell conditions and battery operating limits; the EMS coordinates energy flows using measurements and site priorities. Integration includes status, fault and command exchange with supervisory controls.
03Cooling and protective interfaces
Air or liquid cooling is selected for the system design and environment. Siting considers maintenance access, heat rejection, noise and civil requirements. Detection, protective shutdown and the storage unit's fire protection are coordinated with the arrangements for the whole site.
04Connection and commissioning
The connection point, protection, metering and power limits are reviewed. Commissioning checks communications, operating scenarios and fault responses. Handover includes documentation, user access settings, operator training and a schedule for service inspections.

Before we start
Questions that shape the project.
Can a BESS provide backup power?+
Yes, where the converter, switching equipment and network arrangement support it. Critical circuits, required duration and outage operation are defined in advance.
Can storage be added to existing solar generation?+
Yes, after reviewing electrical connections, metering, communications and available connection capacity. Controls need to coordinate both systems with site demand.
