P91gLi UPS – Rack/Tower Lithium-Ion Online UPS with Up to 15-Year Battery Life

1500VA / 2000VA / 3000VA

208VAC / 230VAC

Rack/tower lithium online UPS for global IT, edge, AV, and networking environments with long-life LiFePO₄ batteries, advanced management options, and high-temperature capability up to 50 °C.

1500 VA – 3000 VA | 208/230 VAC | Online Double Conversion | High-Temperature Operation

The Xtreme Power P91GLi is a high-performance 208/230 V online double-conversion lithium UPS designed for international and higher-voltage environments where uptime, flexibility, and long battery life are critical. It delivers continuous, conditioned AC power with zero transfer time to protect servers, network infrastructure, AV systems, and other sensitive electronics.

Powered by advanced Lithium Iron Phosphate (LiFePO₄) batteries, the P91GLi is designed for up to 15 years of calendar life or 3,000–5,000 charge/discharge cycles under ideal operating conditions, significantly extending service life compared to traditional lead-acid UPS systems. The platform supports ambient operation up to 50 °C (122 °F); output derating applies above 40 °C (104 °F) to maintain reliability and thermal margins.

Its rack/tower convertible design, integrated management capabilities, and scalable runtime options make the P91GLi well suited for global IT infrastructures, edge deployments, and AV systems requiring remote visibility and efficient power protection.

Battery Runtime & Extended Runtime Options

The P91GLi supports optional external battery packs for extended runtime configurations.
