    Product Case

    • 1. Can PC15KT Mobile C&I ESS charge with single-phase 220V? Can it output single phase 220V?

      +

      Yes. You need to add a single-phase 220V to three-phase 380V inverter. The PC15KT supports 220V single-phase output. The rated single-phase output power is 5kW, and the maximum power is 7.5kW but the duration is 1 hour. 

    • 2. Can PC15KT mobile energy storage system connect to solar panels? What is the solar MPPT voltage range?

      +

      Yes. It supports connection to solar panels. The solar MPPT voltage range is 160-950V (optimal range 180-900V).

    • 3. Can PC15KT mobile battery energy storage system connect to diesel generators? Can it operate in parallel with a diesel generator?

      +

      Yes. It supports connection to diesel generators and supports parallel operation through the charging port. 

    • 4. Can the PC15KT be remotely controlled via cloud?

      +

      Yes, the system supports full remote monitoring and control through our EMS platform. It supports both OTA remote updates and USB local updates.

    • 5. Can PC15KT mobile generator be used as an UPS?

      +

      Yes. It can function as an UPS, but the load power must be within 15kW. The UPS switch time is 10ms automatic transfer for seamless power continuity.

    • 6. How to control the working of diesel generators?

      +

      The PC15KT controls the start and stop of diesel generators via I/O dry contacts. You can customize the generator start/stop based on load power. PC15KT supports presetting the State of Charge (SOC) percentage to automatically start/stop your generator. 

    • 7. Can it operate in parallel?

      +

      Yes. The PC15KT mobile ESS supports up to 6 cabinets in parallel to reach 90kW / 198kWh. It also supports battery-only parallel connection. 

    • 8. What is the maximum output power when working with a diesel generator? Can it perform peak shaving with generator load sharing?

      +

      The maximum output power is 22kW. The system intelligently balances between battery and generator power. During the power surges (e.g., pump startup), the system can provide instant power support when generators need supplemental power.

    • 9. What certifications are currently being planned for the PC15KT mobile energy storage system?

      +

      For battery: CB (IEC 62619) and UN38.3 certification. For the entire system: CE-EMC (EN 61000-6-2/4), CE-LVD (EN 62477-1, with PV inverter EN 62109-1/2).

    • 10. What's the charging time from generator/grid?

      +

      Approximately 2 hours with a 20kVA generator or 15kW grid connection.

    • 11. What's the battery lifespan?

      +

      Designed for 4,000 cycles while maintaining 80% capacity (approximately 10 years).

    • 12. Do you offer firmware updates?

      +

      Yes, supporting both OTA remote updates and USB local updates.

    • 13. Do the mobile and hybrid ESS products have full UK/EU safety certifications

      +
      • The mobile ESS has already obtained EU CE and EMC certifications, and other mandatory certifications are in progress.
      • It complies with EU laws and regulations and has a high electrical protection rating.
      • The product features multiple safety protections to safeguard users, such as leakage protection, over-voltage protection, and a built-in fire-suppression system.
    • 14. When connected to a diesel generator, can the mobile ESS control its start and stop? How does it work?

      +
      • Automatic recharge on low battery is achieved via dry contact control.
      • Dry contact control of the diesel generator makes wiring and operation simple, with no need for communication protocol integration.
      • The dry contact interface supports 95% of diesel generators on the market.
      • Reduces labor and O&M costs.
      • Supports 4G remote monitoring and operation, as well as single-phase charging.
    • 15. For the mobile ESS / hybrid ESS, how is the instantaneous power output controlled?

      +
      • The hybrid ESS can detect load changes via built-in sensors and deliver instantaneous power to the load within milliseconds.
      • The ESS continuously monitors load variations, and the built-in intelligent EMS automatically adjusts PCS output to meet demand.
      • The EMS has a high level of automation, fast response, and large PCS capacity.
      • Reduces diesel generator fuel consumption, helping customers save costs.
      • Can communicate and control the diesel generator, and upload generator data to the cloud server.
    • 16. Mobile / hybrid ESS with single-phase input/output, how is the waterproofing of the adapters? Are there alternatives to bulky adapters, and how is 50/60 Hz conversion managed?

      +
      • The interface has a high waterproof rating of IP67, built into our product, expected to launch next month, saving customers the cost of additional adapters.
      • The 50/60 Hz conversion is already integrated into the inverter; users just need to set the parameters on the EMS display.
      • Adaptable to different scenarios, supports single-phase and three-phase charging for user convenience.
      • Enables customers to deliver three-phase power through the mobile ESS even when only single-phase power is available.
