Key features

Massive Scalable Capacity: 115.2kWh single cabinet capacity; supports parallel expansion up to 10 units on-grid (~1.15MWh) and 4 units off-grid.
Built-in Isolation Transformer: Integrated isolation transformer and high-efficiency inverter (98.6% max efficiency) provide complete electrical isolation and superior power quality.
Published changeover reference: the manufacturer lists grid switching below 10ms. Confirm the exact model’s operating mode and connected equipment’s interruption tolerance; this figure does not guarantee that every critical load remains running.
Dual Thermal Control: Air conditioning cooling combined with intelligent air cooling ensures consistent cell temperatures across -20°C to 55°C.
Turnkey All-in-One Deployment: Pre-wired floor-mounted cabinet requires only external AC/DC connection, drastically cutting installation labor and time.
Multi-Layer Safety & 10-Year Warranty: Integrated aerosol fire suppression, smoke and gas detection, anti-islanding, insulation impedance detection, and a 10-year warranty.
