FAQ

  • What are the specific application scenarios for commercial and industrial energy storage?

    ① It is suitable for high energy-consuming enterprises such as steel and chemical plants to leverage peak-valley electricity price differences for arbitrage, thereby reducing electricity costs.

    ② It serves as a backup power source for enterprises with high requirements for power supply continuity, such as data centers and semiconductor manufacturing.

    ③ In parks with abundant distributed photovoltaic resources, it enables local energy consumption and enhances the self-consumption rate of solar power.

  • What are the primary functions of energy storage systems in the commercial sector?

    ① Enables "peak shaving and valley filling" for buildings like shopping malls and office towers, significantly reducing electricity costs.

    ② Serves as emergency backup power for hotels and hospitals, ensuring critical equipment remains operational.

    ③ Integrates with solar PV to store excess electricity and enhance energy independence.

  • What are the main returns on investing in a commercial and industrial energy storage system?

    The primary return is achieved through electricity bill savings from peak-valley price arbitrage and reduced demand charges. Additional benefits include improved power supply reliability and enhanced brand image from using green energy.

  • How to ensure the safety of commercial and industrial energy storage systems?

    ① Select high-quality equipment with safety certifications;

    ② Ensure the BMS monitors battery status in real-time;

    ③ Standardize installation with correct electrical connections and complete fire protection facilities;

    ④ Conduct regular maintenance and implement intelligent remote monitoring.

  • How to Determine if an Energy Storage Battery Needs Replacement?

    Battery replacement should be considered if any of the following conditions occur: the capacity drops below 70% of the rated capacity, the charge-discharge efficiency decreases significantly, the battery shows physical defects such as swelling, leakage or deformation, or the BMS (Battery Management System) detects an abnormal increase in internal resistance.

  • How to troubleshoot an inverter (PCS) fault alarm?

    Possible causes include:

    ① Loose electrical connections;

    ② Abnormal input/output voltage;

    ③ Damage to power components (e.g., IGBT);

    ④ Cooling fan failure or blocked air ducts;

    ⑤ Control circuit or sensor malfunction.

  • What does routine maintenance of an energy storage system include?

    Routine maintenance covers the following aspects:

    ① Visual cleaning and inspection;

    ② Tightening of electrical connections;

    ③ Measurement of key parameters such as voltage and current;

    ④ Inspection of the cooling system;

    ⑤ Software version updates and data backups.
