FAQ
| No. | Question | Answer |
|---|---|---|
| 1 | What is the actual usable capacity of this system? | The system has a nominal capacity of 240kWh (based on 857.6V × 280Ah). For optimal battery longevity, we recommend a maximum depth of discharge (DOD) of 80%, which provides approximately 192kWh of usable energy per cycle. |
| 2 | How long does it take to fully charge the system? | With the recommended 140A charging current, a full charge from 0% to 100% takes approximately 2 hours under ideal conditions. Actual charging time may vary depending on input power availability and ambient temperature. |
| 3 | Can this system be integrated with solar panels or wind turbines? | Yes, this off-grid storage system is fully compatible with renewable energy sources such as solar PV arrays and wind turbines. It works seamlessly with standard hybrid inverters and charge controllers for hybrid energy systems. |
| 4 | What maintenance is required? | The system requires minimal maintenance. We recommend periodic visual inspections of the cabinet, cable connections, and cooling fans every 3–6 months. The BMS performs continuous self-diagnostics and alerts for any anomalies. |
| 5 | Is the system weatherproof? Can it be used outdoors in rain or snow? | Yes, the cabinet is specifically designed for outdoor installation with weatherproof enclosures (minimum IP54 rating, please confirm specific IP rating with sales team). It can operate safely in rain, snow, and dusty environments within the specified temperature ranges. |
| 6 | What is the warranty and expected lifespan? | The system comes with a 1-year standard warranty. With proper operation and maintenance, the LiFePO₄ battery cells are designed to deliver over 6,000 cycles, which translates to approximately 10–15 years of service life under typical daily cycling conditions. |
| 7 | Does the system include a built-in inverter? | Please confirm with our sales team, as the inverter may be integrated or supplied separately depending on the specific configuration. The base system includes the battery pack and BMS; inverter can be customized per project requirements. |
| 8 | Is CE certification valid for all markets? | CE certification confirms compliance with European safety and environmental standards. For other regions (e.g., UL for North America, UN38.3 for transport), additional certifications may be available upon request. |
