FAQ

  • 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.

  • How does the energy storage system coordinate with an existing photovoltaic system?

    Through an intelligent Energy Management System (EMS) for coordinated control, it prioritizes the use of solar power, stores excess energy, and discharges when solar generation is insufficient to maximize self-consumption.

  • What are the site requirements for installing a commercial and industrial energy storage system?

    The site requires a solid load-bearing ground, adequate ventilation and heat dissipation conditions, compliant fire safety clearances, and a location conducive to cable routing. It can typically be installed on the ground, rooftop, or within a dedicated energy storage container
