  • Equipped with module-level and system-level fire detection and extinguishing systems, and compliant with IP67/IP54 protection ratings.
  • We integrated PCS, BMS, and EMS into a single design, enabling system expansion.
  • We offer flexible charge/discharge solutions with 2-hour, 4-hour, and 8-hour options.

Taiwanese quality x Japanese security

By integrating a Taiwanese-made energy storage system with a Japanese domestic Energy Management System (EMS), we clarify the data storage location and communication path. Prioritizing compliance with strict Japanese security standards, we support secure energy operation while minimizing information risks.

BCP measures (high-speed backup)

It functions as a power source to replace or supplement emergency generators, and enhances business continuity (BCP) by continuing to supply power to critical loads even during power outages.

Solar power and energy storage integrated system

By combining solar power generation and battery storage, we can simultaneously reduce electricity costs and ensure a stable power supply.
