    • FAQs

    • Q

      What's the biggest project you have been done before?

      A

      So far, we have finished several 10 MW-20 MWH 0.5C liquid cooling solutions in the across the globe, and what impressed us the most is an American client that has a 30 MWH 0.5C solution for an industrial use, and though we've finished that project for more than 3 years, not a single or a tiny issue has ever been happened to that giant industrial project, and our after-sales team still contacting our valuable client from time to time and ask the situation of that giant project working and offering various assistance including remote or visit in person.

    • Q

      Can the BESS system support black start applications?

      A

      Depending on project configuration, our BESS can support black start functions, allowing the system to help restore power to electrical systems after a complete grid outage.

    • Q

      Can the Sunpal 500kWh BESS system participate in demand response programs?

      A

      Yes. With an intelligent EMS, the system can support demand response strategies by automatically adjusting charging and discharging schedules according to grid conditions and energy demand.

    • Q

      What communication methods does the EMS support?

      A

      The EMS supports remote monitoring through web platforms, mobile applications, and SMS, enabling real-time system status tracking and energy management.
