FAQ

It is the “bridge” between a grid failure and your generator. It provides instantaneous power transition to keep servers, cooling, and networking equipment online without downtime.

Scalable from 15 minutes to 8+ hours. In standard Tier 3 data centers, batteries typically cover the 15–30 minute “critical window” for generator synchronization. However, our modular LiFePO4 systems are fully scalable—we can customize capacity to provide several hours of backup for remote sites or facilities without generators.

70% Space Saving: Higher energy density for compact racks.

10-Year Life: 6000+ cycles vs. 3-5 years for lead-acid.

Zéro maintenance: No watering or acid checks. Significantly lower TCO.

Match three core specs:

Total Load: Your equipment’s peak wattage.

Tension: 48V, 192V, or high-voltage (up to 512V) to match your UPS.

Runtime: Desired backup minutes at full load (add 20% safety margin).
