FAQ

Safety is our top priority. Our system features a Thermal Isolation Safety design where the electrical compartment and battery compartment are physically separated to prevent heat spread. It is fully integrated with professional FM200 or NOVEC1230 fire suppression systems and intelligent thermal sensors for 24/7 real-time monitoring, ensuring automated detection and swift hazard mitigation.

We utilize premium 3.2V / 314Ah Lithium Iron Phosphate (LiFePO4) cells, which offer exceptional energy density and thermal stability. The system guarantees a long service life with a battery cycle count of ≥ 8000 cycles (at 0.5C charge/discharge rate, 25°C), ensuring long-term financial returns for your energy storage projects.

Our BESS features Multi-Mode Flexibility, allowing users to customize working modes based on specific needs. It perfectly supports Commercial & Industrial (C&I) peak shaving and valley filling (energy arbitrage), emergency backup power supply, microgrids, solar-plus-storage integration, as well as grid-side peak regulation and frequency modulation.

The system is equipped with an Intelligent Air Cooling system that works hand-in-hand with our advanced Battery Management System (BMS). It delivers uniform temperature distribution across all battery modules, ensuring the cells consistently operate within their optimal temperature window to maximize efficiency and longevity.

Yes, it is a fully Turnkey, Integrated Design. All core components—including battery racks, BMS, EMS, cooling systems, and fire protection—are pre-assembled and rigorously tested inside the standard container (20ft or 40ft HQ style) before shipping. This rapid deployment design makes it easy to transport, plug and play, and significantly lowers your onsite installation costs and timelines.

Yes, our system fully supports on-grid and off-grid switching. It offers a universal power access design that allows simultaneous access to the grid, battery banks, solar arrays, and diesel generators (DG), making it ideal for weak-grid regions or independent microgrid networks.

Our system ensures premium, grid-compliant power quality. The Total Harmonic Distortion for current (THDi on-grid) is strictly < 3%, and the Total Harmonic Distortion for voltage (THDu off-grid) is < 1% for linear loads and < 5% for non-linear loads, protecting your critical sensitive equipment.

Absolutely. The container enclosure is engineered for extreme outdoor conditions, featuring an IP54 ingress protection rating against dust and heavy rain. Furthermore, it boasts a C5 corrosion protection grade, which means it can withstand highly corrosive marine, coastal, and high-humidity environments effortlessly.

The system is engineered with high-altitude durability, supporting a standard operating altitude of up to 3,000 meters without compromising its insulation or cooling performance.

The container is equipped with a local Touch LCD display for onsite maintenance and natively integrates with our advanced Cloud Platform. It supports standard industrial protocols like RS485 and TCP/IP, enabling your team to perform 24/7 real-time online status monitoring, data analytics, and remote configuration from anywhere in the world.
