Gruber Power Services operates a state-of-the-art depot repair facility staffed by highly trained technicians specializing in the service and restoration of a wide range of critical power protection equipment.

Our capabilities include component-level repair of modules and subassemblies, UPS fan rebuilding, and battery pack reconditioning—all performed with precision and attention to OEM specifications.

At any given time, a high volume of equipment moves through our Depot Repair Center, which features multiple service bays equipped to handle 480V, 208V, and 120V equipment across both single- and three-phase configurations.

To ensure each unit is fully restored to operational excellence, our facility is outfitted with load banks that simulate real-world Data Center conditions, allowing us to verify performance under demanding loads and exceed original manufacturer benchmarks.

We also maintain a dedicated UPS battery module rebuild division, supported by a variety of charging and diagnostic systems for multiple brands. Unlike typical suppliers, Gruber builds and refurbishes battery packs to order—ensuring customers receive freshly assembled units, not pre-aged inventory that has been sitting on a shelf, degrading in performance and lifespan.

The same Depot also serves as an ongoing training and auditing hub for our Field Engineers, who are regularly cycled through for hands-on skill refinement and certification—ensuring that expertise in the field matches the precision of our in-house operations.
