Vertiv GXT5LI-10KGVRT3UXLN Liebert GXT5 10kVA Lithium-ion Online Double-Conversion Rack UPS
Overview
The Vertiv Liebert GXT5LI-10KGVRT3UXLN is a 10,000 VA / 10,000 W online double-conversion UPS built around a lithium-ion battery pack — the architecture that eliminates the VRLA maintenance cycle that forces data center and network closet crews to pull and replace batteries every three to five years. At 3U and hardwired input, this unit belongs in server rooms, edge compute deployments, and security operations centers where uptime is non-negotiable and battery lifecycle cost matters as much as the acquisition price. For organizations building out a power and UPS infrastructure, the GXT5LI-10KGVRT3UXLN sits at the high-capacity end of the Liebert GXT5 family.
Key Features
- 10,000 VA / 10,000 W Unity Power Factor: A unity power factor (1.0) means the VA and watt ratings are identical — no penalty when powering modern server PSUs or high-efficiency network equipment. You can fully load this unit to 10kW without derating. That matters when specifying against legacy UPS designs that run 0.8 or 0.9 PF and deliver meaningfully less usable wattage than their VA label suggests.
- Online Double-Conversion Topology: The load runs from inverted DC power continuously — utility AC never feeds equipment directly. When utility fails, there is zero transfer time because there is no transfer switch to activate. For NVR arrays, network switches, and access control servers, double-conversion also cleans frequency, voltage sags, and harmonic distortion that pass-through (line-interactive) designs let through.
- Lithium-Ion Battery Chemistry: Li-ion cells in this form factor typically deliver two to three times the cycle life of VRLA alternatives and tolerate higher ambient temperatures without accelerated degradation — which directly connects to the 10% derating note at 50°C in the spec sheet. Where a lead-acid UPS in a warm IDF closet might need replacement in 3 years, Li-ion extends that interval significantly and reduces the weight burden during changeout. This is also why the Vertiv UPS line commands a higher upfront cost that frequently pencils out over a five-year TCO horizon.
- Hardwired Input (L1-L2/N-G): The GXT5LI-10KGVRT3UXLN requires a hardwired electrical connection — there is no NEMA plug on this unit. That is appropriate for a 10kW load (branch circuit breaker sizing typically runs 40-50A at 240V) and eliminates connector failure risk at high current. Factor electrician labor into the installation budget; this is not a plug-and-play deployment. Coordinate with your facilities team on the power infrastructure requirements before ordering.
- User-Configurable Output Voltage (200-240VAC ±1%): The default output is 230VAC, but the unit can be configured to match any 200-240V load requirement. The ±1% regulation spec means downstream equipment sees tighter voltage than most utility feeds deliver — relevant for sensitive power supplies and precision measurement equipment.
- 3U Rack Form Factor (5.25 in H × 16.9 in W × 35 in D): At 35 inches deep and 105 lbs, rack planning is serious here. Verify your cabinet has at minimum 36 inches of usable depth and that the rack or floor rail system is rated for the load. Many 2-post open-frame racks will not support this safely — a 4-post enclosed cabinet with a proper UPS slide kit is the right installation context. At 5.25 in (3U), it is dense for the power class.
- Broad Agency Compliance: The GXT5LI-10KGVRT3UXLN carries UL 1778, FCC Part 15 Class A, IEC 62040-1, IEC 62040-2, IEC 62619 (the lithium battery safety standard specifically), IEC 61000-3-2, IEC 61000-3-12, and CISPR 22 Class A. UL 1778 is the UPS safety standard required by most facilities and insurance policies; IEC 62619 compliance is specifically relevant to lithium-ion chemistry and addresses cell safety, overcharge, and thermal runaway protections — an important checkbox for any environment with AHJ review.
- Operating Temperature Range 32°F to 104°F (0°C to 40°C): Standard commercial data center and server closet range. The published 10% derating at 50°C means the unit will continue operating in elevated-temperature environments, but output capacity reduces — plan accordingly if this unit will be deployed in an unconditioned or poorly ventilated space.
Integration and Compatibility
The hardwired 200-240V input requires coordination with building electrical infrastructure — a licensed electrician must terminate the input feed. Output configuration flexibility (200-240VAC user-selectable) allows the unit to match the voltage standard of the protected equipment, making it practical for mixed-voltage rack environments common in international deployments or facilities with legacy equipment. The network and server equipment this UPS is designed to protect typically includes core switching, NVR appliances, access control servers, and edge compute nodes — all of which benefit from the zero-transfer-time double-conversion design.
For organizations evaluating UPS infrastructure for security operations, the GXT5 family integrates with Vertiv's Liebert monitoring ecosystem. Consult Vertiv's management card compatibility documentation for SNMP and remote monitoring options specific to this chassis. If you are building a complete uninterruptible power supply infrastructure and need to size runtime, runtime depends on battery module configuration — confirm with Vertiv's runtime calculator using your actual load profile, not the nameplate rating.
Frequently Asked Questions
Q: Does the GXT5LI-10KGVRT3UXLN require a licensed electrician for installation?
A: Yes. The hardwired input (L1-L2/N-G) means there is no plug — a licensed electrician must terminate the branch circuit feed. At 10kW, branch circuit breaker sizing typically runs 40-50A at 240V. Factor electrician labor and conduit work into your project budget before ordering.
Q: What is the difference between this lithium-ion model and a standard VRLA GXT5?
A: The GXT5LI uses lithium-ion battery cells instead of valve-regulated lead-acid (VRLA) batteries. Li-ion chemistry delivers significantly longer battery service life and tolerates higher ambient temperatures better than VRLA, which typically requires replacement every 3-5 years. The tradeoff is a higher upfront cost that often pencils out favorably over a five-year total cost of ownership comparison.
Q: Will the GXT5LI-10KGVRT3UXLN fit in a standard 2-post open-frame rack?
A: Most 2-post open-frame racks are not appropriate for this unit. At 105 lbs and 35 inches deep, a 4-post enclosed cabinet with a proper UPS slide rail kit is the correct installation context. Confirm your cabinet's depth and weight rating before mounting.
Q: What certifications does the GXT5LI-10KGVRT3UXLN carry?
A: The unit is certified to UL 1778, FCC Part 15 Class A, IEC 62040-1:2008+A1 2013, IEC 62040-2 2nd Ed., IEC 62619 1st Ed. (lithium battery safety), IEC 61000-3-2, IEC 61000-3-12, and CISPR 22 Class A. IEC 62619 is particularly relevant for lithium-ion deployments subject to AHJ review.
Q: Is the output voltage fixed at 230VAC?
A: No. 230VAC is the default, but the output is user-configurable anywhere in the 200-240VAC range with ±1% regulation. This makes the unit usable in environments where the protected equipment requires a voltage other than 230V.
Q: Can this UPS operate in a warm server room or IDF closet above 40°C?
A: The rated operating range is 32°F to 104°F (0°C to 40°C). Above 40°C, the spec sheet documents a 10% output derating at 50°C — the unit will continue operating but at reduced capacity. For consistently warm spaces, either add cooling or derate your load sizing accordingly.
When I look at the GXT5LI-10KGVRT3UXLN, the spec that drives the deployment conversation is the unity power factor — 10,000 VA and 10,000 W are the same number, which means you are not giving up usable capacity to a 0.8 or 0.9 PF penalty the way you do with older UPS designs. For a fully populated 10kW load, that distinction is real money in avoided over-sizing.
Technical Highlights:
- Unity Power Factor (10kVA = 10kW): No derating on modern server and switching equipment. A 0.8 PF UPS at 10kVA delivers only 8kW usable — you would need to step up to a larger chassis to match this unit's real-world capacity.
- IEC 62619 Lithium Battery Certification: This is the international safety standard for lithium-ion stationary energy storage. It covers overcharge, thermal abuse, and short-circuit protections — the checklist items AHJs increasingly require for Li-ion UPS in commercial buildings. Having it documented means fewer surprises at permit review.
- Hardwired Input at 10kW: Branch circuit sizing at this load runs 40-50A at 240V. The hardwired termination eliminates connector failure risk at sustained high current — a legitimate failure mode on high-power plug-type UPS units over time.
Deployment Considerations:
- At 35 inches deep and 105 lbs, confirm 4-post cabinet depth and rail weight rating before procurement. A standard 2-post rack is the wrong home for this unit — the weight distribution alone is a problem without front-to-rear rail support.
- The 10% derating at 50°C is documented but easy to overlook in planning. If this unit goes into an IDF closet without dedicated cooling, model your worst-case ambient before committing to a load close to the 10kW nameplate — you may need to stay at 9kW to maintain margin.
The GXT5LI-10KGVRT3UXLN is the right specification for a purpose-built security operations center or a high-density network closet where the project timeline is long enough that battery replacement cost is a real budget line — lithium-ion's extended service life changes the five-year TCO math in a way that justifies the premium over a VRLA equivalent at this power class.
