Current document status
Request exact model/suffix, electrical and thermal table, cell/BMS/PCS/EMS schedule, enclosure/safety architecture, wiring/one-line, transport/certificates, warranty and full BOM before order release.
Current configuration evidence
Keep battery, rack, cabinet and project scopes distinct
A battery component, cabinet and container system have different electrical, safety and delivery boundaries.
Exact delivered layer
The current route is cabinet-level C&I configuration. Confirm whether cells, modules, rack, BMS, PCS, EMS, HVAC, fire system, transformer, switchgear and auxiliaries are included.
Energy and power
Confirm nominal and usable energy, continuous/peak DC and AC power, current, voltage window, C-rate, derating, auxiliary consumption and test basis.
Controls and safety
Confirm BMS/PCS/EMS/PPC interfaces, protocol/firmware, sensing, contactors, cooling, fire detection/suppression, alarms and fail-safe behavior.
Project and documents
Confirm enclosure/IP, foundations/civil, transport, installation, grid/utility studies, commissioning, FAT/SAT, warranty and responsibility matrix.
Storage RFQ checks
Six checks before finalizing storage scope
The final offer must define the exact equipment layer, operating duty and project interfaces.
Exact code and BOM
Request full model/revision, manufacturer, cell/module/rack or system BOM and supplied option schedule.
Energy and duty
State usable-energy target, power, duration, cycles, DoD, ambient, reserve, degradation and acceptance test conditions.
Electrical interfaces
Confirm battery voltage/current, PCS/AC voltage, protection, earthing, cable/terminal, transformer/MV where applicable and one-line.
Controls
Confirm BMS/PCS/EMS/PPC protocols, firmware, meters/CTs, remote access, cybersecurity, control permissions and commissioning.
Safety and site
Confirm thermal design, fire architecture, ventilation, enclosure, spacing, transport, civil works, emergency response and local approvals.
Evidence and commercial scope
Request test/certificate scope, manuals, warranty, spares, packing, lead time, FAT/SAT and substitution controls.
Storage boundaries
A kWh or MWh headline is not a complete storage-system guarantee
Usable energy, performance, safety and compliance depend on exact equipment, test conditions and project integration.
Nominal is not usable energy
Usable energy varies with DoD, power, temperature, ageing, reserve, BMS limits and auxiliary consumption.
Battery is not a complete ESS
A cell/module/rack route does not include PCS, EMS, HVAC, fire, AC/MV, enclosure, installation or commissioning unless explicitly listed.
Cabinet/container is not turnkey by default
Confirm every BOM layer, site/civil scope, grid interface, transformer/switchgear, transport, installation and acceptance responsibility.
Safety and approvals are site-specific
Do not infer destination fire, transport, grid or building approval from generic labels; verify exact model and project evidence.

Storage RFQ FAQ
Questions to close before selecting a storage product
Exact model documents and project integration determine the final answer.
Is GCB-E257 125 kW / 257 kWh energy storage cabinet a complete delivered system?
Not from the current sourcing record alone. Confirm the full BOM and whether battery, PCS, EMS, HVAC, fire, AC/MV, installation and commissioning are included.
Can the nominal energy be used as usable project energy?
No. Confirm DoD, power, temperature, BMS limits, ageing, reserve, auxiliaries and the test basis.
Will it pair with any inverter or PCS?
No. Confirm voltage/current, BMS protocol, firmware, contactor/protection, approved compatibility and warranty for the exact pair.
What should the RFQ request?
Request exact model/BOM, electrical and thermal tables, controls, safety architecture, one-line, test/certificates, warranty, packing, FAT/SAT and project scope.
