The largest standard plug-and-play UPS size available in North America
A 5kVA 208V UPS is the highest-capacity UPS you can plug into a standard 30A L6-30R receptacle, delivering up to 5000 watts (1.0 PF) of continuous, clean power. This makes 5kVA systems the leading choice for IT racks, AV production, industrial controls, PoE switching, edge computing, and healthcare devices.
Xtreme Power offers a complete range of 5kVA UPS solutions in both VRLA and LiFePO₄ (LFP) battery technologies—including ultra-dense 1U lithium 5kVA UPS systems.

Why Watt Rating Matters More Than VA
A 5kVA rating does not guarantee 5000 watts of usable output.
Modern UPS systems with 1.0 power factor (PF) deliver the full 5000W; older UPS models may deliver only 4000–4500W.
| UPS Type | Typical Power Factor | Usable Output (W) | Benefit |
| Older VRLA UPS | 0.8–0.9 PF | 4000–4500W | Less usable power |
| XPCC Online 5kVA UPS | 1.0 PF | 5000W | Maximum output capacity |
