Description

Product Description

• Fully integrated outdoor BESS cabinet combining high-capacity LFP battery storage and a 110 kW PCS in one turnkey unit for grid-tied and off-grid energy storage applications.

• Uses advanced liquid cooling with AI thermal balance to maintain uniform cell temperatures and improve system efficiency and longevity.

• Fast on/off-grid switching (≤ 20 ms) provides continuous power for backup-critical loads.

• Three-level safety protections including pack, rack, and PCS overcurrent safeguards and a comprehensive fire safety design (gas, smoke, and heat detectors with suppression).

• Remote monitoring and operation supported via Ethernet and cloud platforms (iSolarCloud), enabling real-time performance monitoring and remote firmware updates.

• Scalable and flexible configuration supporting 2 h or 4 h energy durations and parallel connections up to 10 units for larger installations.

• Designed for outdoor exposure with durable IP55 protection and corrosion-resistant enclosure suitable for commercial environments.
