Vertiv Liebert GXT4 UPS — Used & Refurbished (Vertiv)

How Much Does Vertiv Liebert GXT4 UPS Cost in 2026?

In 2026, used Vertiv Liebert GXT4 UPS units (5-20kVA) typically range from $200 to $8,000, depending on condition and configuration. A used unit with original batteries and no cosmetic damage might fetch $1,200–$2,500, while vendor-certified refurbished models (w/ 1-year warranty) average $3,500–$5,500. High-capacity variants (15–20kVA) with redundant modules can exceed $7,000. Compared to the 2026 OEM list price (~$15,000 for a 10kVA unit), buyers save 85–95%. Caveat: Units older than 8 years (pre-2018) often require battery replacement ($400–$1,200), which can eat into savings.

Vertiv Liebert GXT4 UPS Specifications and Compatible Systems

The GXT4 series (2008–2016) offers 5–20kVA capacity, 94–96% efficiency, and 208/230V input. Key specs: 120/208V 3-phase output, 5–15kW power factor-corrected, and battery runtime (15–45 mins at full load). Compatible with servers like Dell PowerEdge 1950–14G (2010–2017), HP ProLiant DL380 G7–G9 (2011–2018), and IBM System x3650 M3–M5 (2011–2019). Warning: The GXT4’s analog interface lacks SNMP support, making it incompatible with modern DCIM tools without retrofitting. Avoid pairing with blade systems requiring redundant 480V inputs.

What to Check Before Buying a Used Vertiv Liebert GXT4 UPS in 2026

1. Battery health: Use a battery analyzer (e.g., MidNite Solar MN-BA-100) to measure Ah capacity. Replace if below 80% of rated value (common in units >5 years old).
2. Transfer switch timing: Test with a load bank (e.g., Siglent SDG 1020X) to ensure switch-to-battery occurs within 4ms. Delays >6ms risk data corruption.
3. Capacitor swelling: Inspect rectifier and inverter capacitors for bulging (use a flashlight and magnifying glass). Replace if >5% height increase.
4. Firmware version: Check via Liebert’s NPS software. Units with firmware pre-2015 lack critical thermal management updates.
5. Rackmount compatibility: Measure clearance for 19” EIA racks. Some GXT4 models use non-standard footprints for dual 19” rail systems.
