Battery Energy Storage System Prefabrication Solution
A structurally engineered enclosure that keeps battery systems protected
ETENZ prefabricates battery-storage enclosures and integrates power, thermal, fire, security and monitoring interfaces, so units ship factory-tested and assemble on site as modules.

Integrated Power and Cooling
Distribution and thermal control are sized to the storage load to keep the cabin environment stable.
Multi-Level Fire and Security Interfaces
Pack-, cluster- and cabin-level fire, access and video interfaces are provisioned per project.
BMS/EMS Monitoring Interfaces
Battery and energy-management monitoring interfaces route straight to the customer's main system.
OEM/ODM Delivery Tiers
Choose a tier from bare enclosure to fully badged cabin based on the scope of partnership.
Corrosion- and Weather-Resistant Enclosure
A galvanized steel and rockwool enclosure is built by ETENZ for harsh outdoor duty.
Application Scenarios
New grid-side / C&I storage
For new-build storage serving grid-side peak shaving and frequency regulation or commercial and industrial peak shifting, prefabricated enclosures form storage units quickly.

Benefits
Renewable-paired storage (solar / wind)
Storage paired with solar and wind sites, laid out in coordination with step-up and grid-connection equipment to support renewable integration.
Benefits
Brownfield expansion and retrofit
When adding capacity or retrofitting an existing site, standard storage enclosures extend capacity quickly and reduce on-site construction.
Benefits
Overseas and remote deployment
For storage deployments overseas and in remote areas, complete enclosures ship to site ready to install and stand up to demanding operating environments.
Benefits
Detailed Solution
Enclosure and zoning: containerized or skid-mounted steel enclosures, zoned into battery area, distribution area and maintenance aisle; galvanized roof panels and corrugated wall panels with rock-wool insulation, C3–C5 corrosion protection, and IP54–55 ingress protection (up to IP65), built for long-term outdoor operation.
Power distribution and tie-in: low-voltage distribution and cable routing inside the enclosure, with interfaces provisioned for PCS, step-up and grid-connection equipment; the specific distribution capacity and electrical parameters are determined by the battery and PCS configuration (project-confirmed).
Thermal management: ventilation, HVAC or liquid-assist cooling is configured to the enclosure's heat load to hold the battery operating-temperature range; the cooling method and redundancy are confirmed to the project environment.
Fire and security: Pack-, cluster- and enclosure-level fire detection and release interfaces and pressure-relief design are provisioned, with access control and video security integrated; the suppression medium and interlock strategy are configured to the project's safety requirements and local codes.
Monitoring interfaces: monitoring and alarm interfaces for BMS battery management and EMS energy management are pre-provisioned for connection to the customer's master control and upper-level systems (interfaces are ready; operation and dispatch remain with the customer or system party).
Delivery and interface boundary: ETENZ delivers the prefabricated enclosure with the above subsystems integrated, and offers tiered delivery from bare enclosure to OEM/ODM white-label; the battery, PCS and EMS are supplied by the equipment party or integrated within the confirmed scope.
