FAQ

Why use LiFePO4 (LFP) chemistry for commercial storage?

LiFePO4 (Lithium Iron Phosphate) is the industry gold standard for C&I applications due to its superior thermal stability, safety profile, and long cycle life (6,000+ cycles), outperforming traditional Lead-Acid or NCM batteries.

How much backup time can the 241kWh capacity provide?

This depends on your critical load. For instance, it can support a constant 50kW load for approximately 4.5 hours. We recommend auditing your essential equipment to determine the exact backup duration required.

Is the system scalable if my energy needs grow?

Absolutely. Our 125kW/241kWh cabinet supports parallel configuration for up to 8 units, scaling your capacity up to 1000kW/1.9MWh to grow alongside your business operations.

What is the transition time during a power outage?

The system features an integrated STS (Static Transfer Switch) that ensures a seamless transition to backup mode in less than 10ms. This prevents downtime for sensitive equipment like servers or precision manufacturing lines.
