FREQUENTLY ASKED QUESTIONS

1. What safety certifications do your C&I cabinets and utility-scale systems hold?

Our BESS solutions feature universal compatibility with major inverters (e.g., SMA, Sungrow, Huawei) and support AC/DC coupling. We provide grid-code-compliant interfaces (IEEE 1547, IEC 61727) for seamless solar integration and dual-mode operation (grid-tied/off-grid). Customizable communication protocols (Modbus, CAN, DNP3) ensure smooth SCADA/EMS integration.

2. What safety certifications do your C&I cabinets and utility-scale systems hold?  

Our systems comply with the highest international safety standards, including UL 9540/9540A (system level), UL 1973 (battery standards), IEC 62619 (safety for industrial batteries), and UN 38.3 (transportation safety). All products undergo rigorous third-party testing for fire resistance, thermal runaway prevention, and electrical safety.

3. What’s the typical ROI timeline for a 500kWh C&I installation in high-electricity-cost regions?  

In regions with electricity costs exceeding $0.25/kWh (e.g., California, Germany), a 500kWh system typically achieves ROI in 3–5 years through peak shaving, energy arbitrage, and demand charge reduction. Our design team provides free ROI simulations based on local tariffs and usage patterns.

4.Do your large-scale systems support black start capability for grid resilience?

Yes, our utility-scale BESS (≥1MW) offers black start functionality via integrated PCS systems with grid-forming inverters. This enables autonomous microgrid restoration within seconds during grid outages, certified to IEEE 1547.4 standards.

5. What thermal management systems are used? (Air/liquid cooling) and why?  

We use liquid cooling for utility-scale projects (>2MWh) and high-density C&I cabinets. Benefits include:

•  ±1°C cell temperature uniformity  

•  40% lower degradation vs. air cooling  

•  25% smaller footprint

For smaller C&I units (<500kWh), we offer forced-air cooling with IP55-rated enclosures for cost-effective deployment.

6. What’s the expected cycle life at 80% DoD for your lithium iron phosphate (LFP) batteries?  

 Our LFP batteries deliver ≥6,000 cycles at 80% DoD while retaining ≥80% capacity (25°C ambient, 0.5C cycle). This translates to 15+ years of operation in daily cycling applications.

7. How do you mitigate fire risks?

Our 5-layer safety approach includes:

  1.  Cell-level: Thermal runaway stoppers (CERTS) in each LFP cell  
  2. 2.  Pack-level: Flame-retardant materials & gas venting channels  
  3. 3.  System-level: AI-driven thermal runaway early warning (detects anomalies 30+ mins pre-failure)  
  4.  Active protection: Multi-stage aerosol fire suppression

5.  Design: 2-hour fire containment enclosures (UL 9540A certified)

8. Can your C&I cabinets be stacked/outdoor-deployed in limited spaces?  

Yes, our C&I cabinets feature modular stacking design (up to 4 units vertically) with IP55 protection for outdoor use. A 250kWh system requires only 2.5m² footprint. Optional climate-control kits extend operating range to -30°C to 50°C.  

9. What SCADA/EMS platforms do your utility-scale systems interface with?  

We support integration with OSIsoft PI, Siemens Spectrum Power™, ETAP, and Ignition SCADA via standard protocols (DNP3, IEC 61850, MQTT). Our API-first architecture enables custom EMS/BMS integrations within 2–4 weeks.   

10. What warranty is provided for degradation (e.g., 70% capacity after 10 years)?

We offer a 10-year warranty with: •  Year 10 capacity retention ≥70%  •  End-of-warranty throughput guarantee (e.g., 15 MWh per 1MWh capacity)  •  Pro-rata coverage for premature degradation

11. How do you handle end-of-life battery recycling? 

We partner with R2/RIOS-certified recyclers globally for closed-loop recovery:

•  ≥95% material recovery rate (Li, Co, Ni, Cu)

•  Blockchain-tracked recycling chain  

•  Optional buy-back program for core materials  

12. What’s the response time for grid-frequency regulation (e.g., 100MW system)?  

  Our BESS achieves <200ms response from grid signal to full power delivery (100MW scale), exceeding FERC 755 requirements. Ramp rates reach 100% PN in 500ms for primary frequency response. 

13. Do you offer performance guarantees for energy throughput?  

Yes, we provide performance insurance guaranteeing:

•  Annual energy throughput (e.g., 365 cycles/year at 90% DoD)  

•  Round-trip efficiency ≥88% (AC-AC)

 •  Availability ≥98.5% (excluding planned maintenance)

14. What cybersecurity protocols protect your BESS controls from breaches?  

 We implement IEC 62443-3-3 standards with:

 •  Hardware: Zero-trust architecture, hardware security modules (HSM)

 •  Software: Encrypted comms (TLS 1.3), role-based access control

 •  Certifications: NIST CSF, ISO 27001-compliant firmware

15. Can you provide case studies for [Industry] applications?  

We have documented success across sectors:

•  Manufacturing: 2.4MWh peak shaving for auto plant (Spain)  

•  Data Centers: 4.8MWh UPS + solar integration (Singapore)

 •  Utilities: 100MW/200MWh frequency regulation (Chile)
