Product Q&A

Q:Are containerized BESS safe? What happens if a cell fails or overheats?

Safety is engineered in. Each 5MWh unit features module-level fire isolation with aerosol suppression - battery modules are physically partitioned so thermal runaway cannot propagate between modules, while the built-in BMS continuously monitors cell status for early protection.

Q:How complex is on-site installation, and how fast can we go live?

Minimal site work is required. The system is pre-commissioned and factory-tested inside a standard 20ft container with plug-and-play architecture - no on-site battery rack assembly, cutting installation time and cost so your team can operate it sooner.

Q:Can it integrate with our existing SCADA, PCS/inverter and grid requirements?

Yes. The intelligent EMS supports Modbus-TCP, IEC61850 and IEC104 protocols for seamless integration with SCADA systems and grid operators, including remote monitoring and smart energy dispatch in real time.

Q:What if our energy demand grows after the first 5MWh unit?

The architecture is modular and plug-and-play: factory-tested 5MWh units connect in parallel and expand to multi-MWh systems, so you scale capacity as demand grows without re-engineering the original installation.

Q:How long does the battery last? What is the cycle life?

Built on Grade A LFP cells in high-voltage racks, the system delivers more than 10,000 cycles with a 10-year warranty, giving a long service life and predictable long-term cost of ownership.
