G125K-LE260 125kW / 261kWh Liquid-Cooled ESS Cabinet

Current source identity: G125K-LE260 exact model; displayed sources conflict on approximate system weight and do not provide a complete released AC-system BOM.

The G125K-LE260 record identifies a 261 kWh LFP cabinet with a 125 kW AC system class, 130.5 kW DC rated-power wording, an 832 V rated battery platform, 728–936 V range, 157 A standard charge/discharge current and liquid cooling. The current sources differ on approximate weight and do not establish usable AC energy, exact PCS/EMS/BMS BOM, auxiliary consumption, system efficiency, fire approval, grid code or warranty. Those items must be configuration- and project-specific.

Current document status

Request the current cabinet datasheet/manual, exact PCS/BMS/EMS and battery BOM, one-line, usable-energy/RTE basis, liquid-loop data, fire detection/suppression design and approvals, grid certificates, transport plan, warranty and FAT/SAT documents.

Current cabinet evidence

Keep battery, AC-system and project-scope values separate

The exact model is known, but the complete delivered system and performance basis are not yet fixed.

Power and energy identity

The record combines 125 kW AC system-class and 130.5 kW DC rated-power wording with 261 kWh nominal energy. Confirm PCS rating and whether every value belongs to the same released configuration.

Battery architecture

LFP 314 Ah, 1P260S, 832 V rated, 728–936 V and 157 A are listed. Pack/rack composition, BMS hierarchy, usable energy and DC protection require the BOM and one-line.

Liquid cooling

A 50% ethylene-glycol aqueous coolant is stated. Loop volume, pump redundancy, leak detection, heat rejection, ambient derating, maintenance and site interface are missing.

Fire and physical record

Aerosol suppression plus temperature/smoke detection and IP54 are listed. Source weights differ around 2.6–3.0 t; final transport weight, lifting points, approval basis and fire interfaces need released documents.

G125K-LE260 project checks

Six workstreams before approving the cabinet configuration

A C&I cabinet quotation must define AC performance, usable energy, safety, site and service scope.

Duty and operating mode

Define peak shaving, solar shifting, backup/microgrid, cycles/day, power profile, required duration, reserve SOC and grid/export constraints.

Exact BOM

Request PCS, battery packs/racks, BMS, EMS/controller, HVAC/liquid loop, fire system, switchgear, meter, auxiliary supply and communication item numbers.

Performance basis

Confirm gross/usable DC and AC energy, continuous/peak kW, auxiliary load, RTE, efficiency curve, availability, degradation and ambient/altitude derating.

AC and grid interface

Provide voltage/frequency, fault level, earthing, point of connection, transformer if needed, protection study, grid code, meter/CT and export-control requirements.

Site and safety

Confirm foundation/floor load, access, clearances, drainage, coolant containment, noise, ventilation, fire separation, detection/suppression interface and emergency response.

Delivery and acceptance

Request transport/lifting data, FAT/SAT, commissioning, performance tests, training, spares, remote access, warranty, service SLA and handover documents.

Cabinet performance boundaries

261 kWh nominal and 125 kW class do not prove delivered AC service

Performance and safety claims must state the selected BOM, test conditions and responsibility boundary.

Nominal energy is not usable AC energy

Apply SOC window, DoD, cell/BMS limits, auxiliary cooling/fire loads, conversion losses, temperature and degradation.

Cycle count is condition-specific

The displayed 8,000 cycles to 70% EOL at 90% DoD needs test standard, C-rate, temperature, rest periods and a clear relationship to system warranty.

Fire-system labels are not site approval

Aerosol, smoke and temperature labels do not define detection zones, agent quantity, ventilation shutdown, code compliance, AHJ approval or emergency plan.

Liquid cooling is not a performance guarantee

Temperature uniformity, auxiliary consumption, leak control, ambient capacity, redundancy and maintenance determine actual results.

G125K-LE260 FAQ

Questions to close before commercial release

The exact cabinet model still needs a released BOM and project performance basis.

Is 261 kWh the usable AC energy?

No. It is nominal energy. Confirm the warranted usable DC/AC energy after SOC reserve, DoD, losses, auxiliary loads, temperature, power level and degradation.

Why are both 125 kW and 130.5 kW shown?

The record uses 125 kW AC system-class and 130.5 kW DC rated-power wording. Require a released datasheet/BOM that maps both to the same configuration before quoting performance.

Does aerosol fire protection establish site compliance?

No. Confirm the detailed detection/suppression design, standards/tests, ventilation and shutdown logic, alarms, emergency interface and local authority approval.

Which acceptance tests are needed?

Define document review, FAT, delivery inspection, installation checks, SAT, controls/protection tests, usable-energy/RTE or capacity tests, training and final handover.

Prepare a G125K-LE260 project RFQ

Send the duty profile, required usable energy and kW, AC/grid interface, site climate/layout, fire requirements, logistics and performance-acceptance criteria.
