Profitability
Turn efficiency into real energy profit
Max. system efficiency ≥90%
Designed to convert more stored energy into usable site value.
Lower thermal stress
Liquid-cooled consistency supports stable performance in demanding duty cycles.
ROI-led operation
Efficiency data, cycle life, and maintenance visibility work together for project economics.
Solution modules
A complete C&I storage architecture
Each module addresses one project concern: return, expansion, uptime, protection, compliance, control, lifetime, and site durability.
Scale Energy, Scale Profit
Up to 6 units off-grid and 20 units on-grid, with modular expansion as the site grows.
Always On
EMS plus external STS enables fast switching for critical loads with no visible break.
Effortless Control
Touchscreen monitoring and parameter setup simplify daily operation and commissioning.
Safety system
Triple-layer protection from pack to site
FLM500-125/261 combines early detection, pack-level protection, cabinet-level suppression, and an external water fire interface for layered project risk control.
Pack-level aerosol
Protection starts inside the battery pack.
Cabinet-level aerosol
Secondary response layer for the full cabinet.
Temp, smoke, water detection
Multiple sensors help detect abnormal conditions early.
Pressure relief and warning
Structural protection supports safer fault response.
Built for Every Scenario
Engineered for Outdoor Durability in the Harshest Conditions
All-in-one design for faster site work
BMS, PCS, and EMS are pre-integrated in one cabinet. Zero-gap side-by-side installation, IP55 outdoor protection, and C4 corrosion resistance help the system fit factories, ports, microgrids, and harsh environments.
Certified standards
Ready for global project review
Certification coverage gives procurement, engineering, and finance teams a clearer path through technical approval.
