XPC GT90: key facts

Sources, checked October 3, 2026: Xtreme Power Conversion, GT90.

Is the XPC GT90 discontinued? What replaces it?

Yes. Xtreme Power Conversion states that the GT90 has been replaced by the M90Ci-6S. See the XPC M90Ci page.

Units already installed keep working after the manufacturer's cut-off; what changes is parts and factory support. We maintain discontinued units and plan the replacement when it makes sense. How to plan the replacement of a discontinued three-phase UPS.
