FAQs
FAQs: Commercial & Industrial (C&I) Energy Storage Systems
1. Core Technology & Cells

  • Q: Do you use 280Ah or 314Ah cells in your BESS?

    • A: We have upgraded our flagship 261kWh cabinets to high-density 314Ah Grade A LiFePO4 cells. This provides a 12% higher energy density compared to traditional 280Ah cells, offering a more compact footprint and lower Levelized Cost of Storage (LCOS).

  • Q: What is the benefit of Liquid Cooling over Air Cooling for industrial use?

    • A: Liquid cooling is the superior choice for high-power applications. It maintains a cell temperature variance of less than 3°C, ensuring all cells age uniformly. This technology extends the system's lifespan by approximately 20% and allows for higher discharge rates without thermal throttling.

2. Economics & ROI

  • Q: How does a C&I BESS generate revenue for my business?

    • A: Our systems primarily generate value through Peak Shaving and Load Shifting. By discharging during peak hours and recharging during off-peak hours, businesses can reduce their "Demand Charges" on electricity bills by 30% to 40%.

  • Q: What is the typical ROI (Return on Investment) period?

    • A: In high-tariff markets like Europe or North America, most industrial clients achieve a full ROI within 4.5 to 6 years, depending on local subsidies and the frequency of peak-shaving cycles.

3. Safety & Compliance

  • Q: What fire suppression systems are integrated into the cabinets?

    • A: Every cabinet features a multi-level fire protection strategy. This includes smoke and heat sensors linked to an automatic Perfluorohexanone (FK-5-1-12) or Aerosol fire suppression system, designed to extinguish any potential cell issue before it spreads.

  • Q: Is the system suitable for harsh outdoor or coastal environments?

    • A: Yes. Our BESS units are IP55-rated for outdoor use, featuring C4 or C5-level anti-corrosion coating and integrated climate control, making them ideal for high-humidity, dusty, or coastal locations.

4. System Integration & EMS

  • Q: Does the system include an Energy Management System (EMS)?

    • A: Yes, every unit comes with a built-in Smart EMS. This provides real-time local and cloud-based monitoring, allowing you to track energy flow, SOC (State of Charge), and financial savings via a web dashboard or mobile app.

  • Q: Can I connect multiple 261kWh units for a multi-megawatt project?

    • A: Absolutely. Our modular design allows for parallel scalability. You can start with a single unit and expand into multi-MWh systems as your facility's energy needs grow.

Technical FAQs: EXLIPORC 15kWh Residential Energy Storage
1. Design & Installation
  • Q: Can the wheels on the 15kWh unit be removed?
    • A: Yes, the high-durability caster wheels are removable to accommodate different installation preferences.
  • Q: Can the 15kWh battery be installed outdoors under eaves?
    • A: The LVB15WTC has an IP20 protection rating. While it can be placed under eaves, its safety depends on the effectiveness of the rain shielding in that specific location. We recommend a dry, well-ventilated environment for optimal performance.
  • Q: For high-temperature regions like Africa, can we add heat sinks to the 15kWh battery pack?
    • A: Adding passive heat sinks provides limited benefits for this scale of system. For extreme temperature environments, we recommend utilizing active cooling (fans) or ensuring proper cabinet ventilation.
2. Technical Specifications & BMS
  • Q: Which BMS model is used in the 15kWh unit, and does it feature active balancing?
    • A: We utilize the latest JBD UP16S019 smart BMS. It features passive balancing with a balancing current of 40mA.
  • Q: Does the passive balancer cause voltage drift between cells over time?
    • A: Passive balancing uses lower current; if a significant voltage gap develops, it may take longer to rebalance compared to active balancing. However, for well-matched Grade A cells, passive balancing is highly effective for long-term stability.
  • Q: Does the system require an external WiFi dongle?
    • A: No. The current JBD version features a built-in WiFi module, eliminating the need for an external dongle.
  • Q: Is the BMS password-protected? Can I change the settings?
    • A: Basic data reading is open. However, deep parameter settings require an Engineer-level password, which is generally not provided to end-users to prevent incorrect settings that could lead to safety issues or disputes.
  • Q: What is the pre-installed firmware version, and can it be updated?
    • A: The current shipping version is V3. Units are always shipped with the latest firmware. If updates are required in the future, we can provide the necessary PC software and update programs.
3. Safety & Maintenance
  • Q: What is the self-ignition temperature of the 15kWh battery?
    • A: Due to the inherent thermal stability of LiFePO4 (LFP) chemistry, our battery packs do not self-ignite under normal or even extreme operating conditions.
  • Q: I see an error code "80" at startup. What does it mean?
    • A: Error code "80" can be ignored. It occasionally appears as a momentary warning during the initial screen power-on and does not affect the system's operation.
  • Q: What is the normal voltage range when the battery is shipped?
    • A: The standard shipping voltage is between 52V and 53V.
  • Q: Can I purchase extra BMS units and cells as spares?
    • A: Due to the high stability of our cells, we do not recommend keeping spare cells. However, we can provide spare BMS units as backup based on your total order volume.
4. Compatibility
  • Q: Does the 15kWh system support the Voltronic communication protocol?
    • A: Yes, the system is fully compatible with the Voltronic protocol for seamless inverter integration.
