XPC E90: key facts

Sources, checked October 3, 2026: Xtreme Power Conversion, E90.

Is the XPC E90 discontinued? What replaces it?

Yes. Xtreme Power Conversion states that the E90 has been replaced by the E91. See the XPC E91 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.
