| High Light | 125kW LiFePO4 energy storage cabinet ，261kWh liquid cooling BESS ，commercial industrial battery storage system | ||
Model EC-LC261 | Industrial & Commercial Grade BESS
Engineered for continuous industrial duty, the EC-LC261 integrates a 416-series LiFePO4 string, a 125kW bi-directional PCS and a closed-loop liquid cooling circuit inside a single IP54 enclosure. It is designed around one principle: keep every cell within a 3 deg C window for the entire service life, so that capacity retention stays above 80% after 8000 cycles.
The cabinet arrives fully pre-commissioned. On site you connect AC cables, enable the EMS profile and the unit begins its first charge cycle. No separate battery room, no cooling piping installation, no complex integration work.
| Item | Value |
|---|---|
| Rated Power / Energy | 125kW / 261kWh |
| Cell String | 1P416S, LiFePO4 prismatic |
| Voltage Window | 1164.8 - 1497.6 V |
| Coolant Loop | Water-glycol, factory sealed |
| Cycle Life | 8000 @ 80% DOD (15+ yrs) |
| Enclosure | IP54, 1600x1100x2300 mm, ~2800 kg |
Air cooling reaches its physical limit when cell currents rise: the cells nearest the fan run cooler while the core runs hot, and the spread widens with every charge cycle. The EC-LC261 replaces air with a chilled water-glycol plate loop. Each module sits on a cold plate, and the chiller modulates flow by cell temperature rather than cabinet temperature.
Field data from our 2024-2025 commercial installations shows a steady-state cell delta of 1.8-2.6 deg C at full 200A current, versus 6-9 deg C for forced-air cabinets of the same class. Lower delta directly translates to less capacity fade: after 3000 cycles the liquid-cooled string retains 92% capacity in our accelerated aging tests.
Safety is layered at three independent levels. At cell level, the BMS balances and monitors every cell through dedicated NTC sensing. At module level, current interruption devices isolate any faulty module within one millisecond. At system level, aerosol generators flood the cabinet on smoke detection while the EMS executes a controlled discharge sequence. The insulation monitor checks ground resistance continuously and trips the PCS on any anomaly.
| Metric | Result |
|---|---|
| Round-trip efficiency | ≥ 95% (AC side, 25 deg C) |
| Full-power response | < 100 ms |
| Standby loss | < 0.5% of rated energy per day |
| Audible noise | ≤ 65 dB(A) at 1 m |
Manufacturing plants running two-shift operations, cold-chain warehouses with night chillers, EV charging hubs with unpredictable demand spikes, and commercial buildings on time-of-use tariffs. The EMS accepts a tariff table of up to eight periods and a load forecast, then dispatches the cabinet automatically. In outage-prone regions the same unit doubles as site backup.
Five-year parts-and-labor warranty, extendable to ten. Remote firmware upgrades over the cloud portal, annual preventive maintenance visits, and a 24-hour response commitment for critical faults. Factory test reports, CE / TUV / UN38.3 / IEC 62619 certificates and a complete drawing package ship with every unit.
| Stage | Work Content |
|---|---|
| Site preparation | Level concrete pad, cable routes, clearance of 800 mm front and 500 mm rear |
| Positioning | Crane or forklift placement onto pad, four-point leveling |
| Electrical connection | AC output cable, protective earth, optional CT and meter wiring |
| Commissioning | Remote or on-site start-up, insulation test, first charge cycle, EMS profile upload |
| Acceptance | Performance verification against datasheet, handover documents |
The standard package covers five years against defects in materials and workmanship, with capacity guarantee of no less than 80% at the end of the term. The optional extended plan adds five more years plus two preventive maintenance visits per year. Warranty claims are handled by our regional service centers, and most spare parts ship within 48 hours.
