Extend runtime where downtime is not an option. Vertiv GXT PWR PROTECT EBC 288V X2 YRS1-2 is a high-voltage external battery cabinet designed to add battery capacity to compatible GXT UPS systems. For infrastructure teams that need more ride-through than the base UPS can provide, this cabinet helps bridge outages, manage controlled shutdown windows, and keep essential loads protected through utility disturbances. The 288 V battery architecture is built for environments that demand serious runtime extension without changing the core UPS platform. That makes it a practical fit for server rooms, edge sites, and distributed IT deployments where continuity matters more than convenience. The dual-year coverage designation also supports long-term planning for facilities standardizing on Vertiv power protection. Use it when the cost of a brief interruption is measured in lost transactions, failed jobs, or recovery effort. By pairing the UPS with an external battery cabinet, you gain more time to ride through power events and more flexibility to align shutdown procedures with operational policy. For teams comparing options, this model is about extending protection cleanly within the Vertiv ecosystem rather than oversizing the entire UPS stack.
