A custom prefabricated enclosure for a BESS project reaches a buildable quote faster when the RFQ defines equipment data, thermal management, fire interfaces, electrical boundaries and deliverables.
Energy capacity and a 10 ft or 20 ft format are rarely enough to price a BESS enclosure reliably. The same capacity can use different cells, modules, racks, DC voltages, PCS architectures, thermal-control methods and fire strategies, each changing the enclosure and integration scope.
ETENZ turns procurement questions into an engineering input checklist. The earlier the data is complete, the sooner layout, interfaces, responsibilities and deliverables can be frozen—and the closer the quotation is to the final manufacturable scope.
State whether the requirement is enclosure-only, a battery-ready shell, a rack-installed enclosure, a PCS or electrical-interface module, or a factory-integrated unit based on customer-nominated equipment and branding. Each layer needs different inputs, tests, cost elements and lead-time assumptions.
The responsibility matrix should identify who supplies, installs and commissions the batteries, PCS, BMS, EMS, thermal-control and fire equipment. ETENZ can then separate enclosure fabrication, auxiliary-system integration, equipment installation, interface preparation and documentation accurately at quotation stage.
Provide battery chemistry, cell, module and rack models, supplier, quantity and arrangement, mass, DC voltage, capacity, BMS interface, replacement access and permitted environmental conditions. PCS, distribution, control and auxiliary equipment also need dimensions, weight, heat rejection, cable entry and maintenance information.
When equipment data arrives with 2D or 3D layouts, doors, aisles, foundations, cable routes, lifting points and service clearances can enter engineering review early. Certificates and reports should be mapped to the exact equipment and configuration so the evidence schedule stays traceable.
Thermal planning needs battery and PCS heat data, site temperature and humidity, altitude, target internal conditions, ventilation or liquid-cooling/HVAC scope, condensation control and loss-of-power assumptions. Complete inputs allow airflow, equipment positions, piping or duct interfaces and service access to be designed together.
Fire and monitoring inputs should define detection, alarm, releasing, emergency stop, pressure relief, remote signals and project-approval interfaces. ETENZ can then prefabricate openings, mounting provisions, cable routes and controls around the confirmed equipment strategy.
Define PCS, transformer or MV interfaces, auxiliary power, grounding, cable entry, metering, BMS, EMS/SCADA and remote-monitoring boundaries. Early single-line diagrams, equipment lists, terminal schedules, protocols and signal lists make it easier to design power, controls and penetrations correctly the first time.
If batteries travel inside the enclosure, the exact battery model, loading configuration, transport mode and destination determine the UN 38.3 test summary, SDS, state of charge, marking, declarations and forwarder review. Enclosure dimensions, mass, centre of gravity, lifting, packing and arrival inspection also need confirmation.
The handover schedule can include general arrangements, manufacturing drawings, BOMs, inspection and FAT records, packing data, operation and maintenance documents, and equipment certificates. Defining these at RFQ stage keeps price, milestones and final deliverables aligned.
Capacity and container size are only the starting point. A complete package covering delivery layer, equipment, thermal management, safety, electrical interfaces, logistics and documents lets ETENZ review the project faster and propose a clearly scoped BESS enclosure manufacturing and integration route.
The 20 ft 5 MWh Battery Energy Storage Container is ETENZ's containerized BESS for grid & C&I storage projects. Rated at a nominal 5 MWh, it arranges multiple battery-rack rows inside a standard 20 ft ISO container and pre-integrates power distribution, HVAC, fire detection with pipe-network suppression, combustible-gas detection and monitoring as subsystem interfaces. ETENZ manufactures the enclosure and handles subsystem integration; battery modules and the PCS are supplied or pre-reserved per project scope. Delivery ranges from empty enclosure and rack-ready cabin to finished cabin and OEM/ODM private label, suited to storage stations, C&I storage and renewable grid-connection sites.
The 10 ft All-in-One Energy Storage Cabin is ETENZ's compact, containerized BESS enclosure built for commercial and industrial (C&I) energy storage. Inside a standard 10 ft container structure it integrates battery racks, a hybrid inverter and interfaces for power distribution, environmental control, fire protection and monitoring subsystems. ETENZ handles enclosure manufacturing and subsystem integration; the battery and hybrid inverter are supplied by scope or reserved as integrated equipment. Delivery scales from bare enclosure to rack-mounted, finished cabin and OEM/ODM private-label — fitting C&I storage, microgrid and backup-power applications.
