Vertiv GXT5LI-6000MVRT3UXLN 6000VA Li-Ion Double-Conversion Online UPS
Overview
The Vertiv GXT5LI-6000MVRT3UXLN is a 6000VA/6000W double-conversion online UPS built for rackmount deployments where clean, continuous power matters — think NVR stacks, edge compute nodes, network closets, and mid-size server rooms that cannot tolerate even a millisecond of power transfer time. The GXT5 LI line uses lithium-ion battery chemistry in a 3U rackmount chassis, delivering 6kVA of online power protection in a 100 lb package that fits standard 19-inch racks. Unlike line-interactive or standby designs, the online double-conversion topology regenerates output power entirely from the inverter at all times — the utility grid never directly feeds your load, so sags, surges, noise, and frequency drift are all isolated before they reach your equipment.
Output is configurable between 120V/208V and 120V/240V via user-accessible settings, and input accepts 120V or 240V — which gives you flexibility when rack power infrastructure changes or when you're standardizing across mixed-voltage environments. Wiring is hardwired (L1, L2, N, G), consistent with commercial electrical installations rather than plug-in consumer UPS units.
Key Features
- Double-Conversion Online Topology: The inverter is always active — there is no transfer time when grid power degrades. For surveillance NVRs, network switches, or access control servers, this means zero-interruption ride-through during brownouts and switching transients that would reset a line-interactive unit mid-write.
- 6000VA / 6000W at Unity Power Factor: Most commercial UPS systems derate at 0.8 or 0.9 power factor. The GXT5LI-6000MVRT3UXLN delivers its full 6000W at unity PF — you can load it to nameplate without arithmetic adjustments. Budget your load directly in watts.
- Lithium-Ion Battery Chemistry: Li-Ion cells (certified to UL 1642 and the battery pack to UL 1973) offer longer calendar life and faster recharge compared to VRLA lead-acid. For dense rack environments where battery swap logistics are expensive, longer cell life reduces maintenance cycles.
- User-Configurable Output Voltage (120V/208V or 120V/240V): If your downstream load mix changes — adding 208V PDUs alongside 120V equipment — output can be reconfigured without replacing the UPS. This matters in security infrastructure buildouts where rack contents evolve over project phases.
- 3U Rackmount, 35-inch Depth: At 5.2 in H × 16.9 in W × 35 in D, this unit occupies 3U in a standard rack. The 35-inch depth is a real constraint — verify your rack's usable depth before ordering; shallow-depth telecom racks (24–28 in) will not accommodate it.
- Hardwired Input/Output (L1, L2, N, G): Hardwired connections are standard on commercial-grade UPS at this power level. Plan for a licensed electrician during installation — this is not a plug-and-play appliance. The benefit: no connector derating, no plug heating under sustained load.
- Network Interface via RDU101 (RJ-45) + Serial + USB: Three management paths give you options for integration. The RDU101 network card allows SNMP monitoring and remote shutdown — required for any environment using NMS platforms. Serial and USB provide local or scripted management without consuming a network card slot.
- Operating Temperature 32°F–104°F (0°C–40°C): Standard commercial operating range. Note the 10% derating at 50°C — if your machine room runs hot (above 40°C), plan for derating in your load budget. At 50°C, effective capacity drops to approximately 5400W.
- Energy Star 2.0 Certified: In a 24/7 online topology, efficiency directly affects your operating cost. Energy Star 2.0 qualification indicates the unit meets minimum efficiency thresholds at 25%, 50%, 75%, and 100% load — relevant when calculating annual PUE impact in a monitored data center or server room.
- UL 1778, c-UL, CSA 22.2 No. 107.3, FCC Part 15 Class A: Full North American safety and emissions certifications. UL 1778 is the primary UPS safety standard; FCC Part 15 Class A limits radiated emissions to commercial (non-residential) levels — appropriate for the rack environments this unit targets.
Integration & Compatibility
The GXT5LI-6000MVRT3UXLN integrates into standard power and UPS infrastructure via its RDU101 network management card slot, enabling SNMP v1/v2/v3 communication with building management systems, NMS platforms, and NVR and server environments that support graceful shutdown on power events. The hardwired input feeds from a dedicated 208V or 240V branch circuit — coordinate with your electrical contractor on breaker sizing per NEC guidelines for continuous loads (125% of the UPS input current rating is the standard starting point).
For security integrators deploying Vertiv power infrastructure alongside NVR stacks or edge compute nodes, the USB and serial interfaces allow integration with server-based shutdown agents (most major OS vendors ship UPS daemon support natively). The RJ-45 network port with the RDU101 card supports remote monitoring without requiring a dedicated management workstation on-site — a practical requirement in unmanned equipment rooms.
Rack planning note: at 100 lbs, this unit requires a rail kit rated for the weight and, on two-post racks, a UPS-specific shelf. Verify your rack and mounting hardware is rated for this load before installation. For deployments where extended runtime beyond the internal battery is needed, the XL designation supports external battery cabinets — check Vertiv's XL-compatible external battery options for this model family.
Frequently Asked Questions
Q: What is the transfer time to battery on the GXT5LI-6000MVRT3UXLN?
A: Zero milliseconds. The double-conversion online topology means the inverter is always active and powering your load — there is no transfer switching event when grid power fails or degrades. Your connected equipment never sees a break in conditioned power.
Q: Can the GXT5LI-6000MVRT3UXLN run on a standard 120V outlet?
A: No. This unit uses hardwired input (L1, L2, N, G) and requires a dedicated 120V/240V branch circuit with a licensed electrician for installation. It is not a cord-and-plug appliance.
Q: What output voltage does the GXT5LI-6000MVRT3UXLN deliver, and can it be changed?
A: Output is user-configurable between 120V/208V and 120V/240V. This can be set without replacing the unit, giving flexibility if your downstream load mix changes during a deployment.
Q: Does the GXT5LI-6000MVRT3UXLN support remote network monitoring?
A: Yes. The unit includes an RJ-45 network interface via the RDU101 card, plus serial port and USB, supporting SNMP-based remote monitoring and graceful shutdown integration with NMS platforms and server OS shutdown agents.
Q: Will the GXT5LI-6000MVRT3UXLN fit in a standard 24-inch-depth rack?
A: No. At 35 inches depth, it requires a rack with at least 35 inches of usable interior depth. Shallow-depth telecom or wall-mount racks will not accommodate this unit — verify your rack's depth specification before ordering.
Q: What certifications does the GXT5LI-6000MVRT3UXLN carry?
A: UL 1642 (Li-Ion battery cells), UL 1973 (Li-Ion battery pack with UPS), UL 1778, CSA 22.2 No. 107.3, c-UL, FCC Part 15 Class A, and Energy Star 2.0.
The GXT5LI-6000MVRT3UXLN is one of the few UPS units in this power class that actually delivers unity power factor — 6000W at 6000VA, no derating math required. That matters when you're sizing power protection for a rack full of switching-mode power supplies, where most competitors' 6000VA ratings translate to only 4800W of real capacity. I spec this unit specifically when the load budget is tight and the electrician has already run the dedicated 208V circuit.
Technical Highlights:
- Double-Conversion Online Topology: Zero-transfer-time protection at all times — no switching event on power failure or brownout. Critical for surveillance NVR recording continuity and access control servers where a 20ms gap can cause a write failure or door controller reset.
- Li-Ion Battery (UL 1642 / UL 1973 Certified): Longer calendar life than VRLA and faster recharge after a discharge event. In unmanned equipment rooms where battery swap scheduling is difficult, fewer maintenance cycles over the system's lifecycle is a real operational advantage.
- RDU101 Network Management + Serial + USB: Three independent management interfaces mean you're not locked into a single monitoring path. SNMP via the RDU101 integrates with Vertiv's management software and third-party NMS platforms; USB handles local OS-level shutdown scripting without consuming a network port.
Deployment Considerations:
- Hardwired input (L1, L2, N, G) is non-negotiable — budget for a licensed electrician and a dedicated branch circuit. NEC continuous-load rules apply: size the breaker at 125% of the UPS input draw, not the nameplate output.
- At 35 inches deep and 100 lbs, rack selection matters. Confirm your rack's usable interior depth before ordering — this unit will not seat in 24- or 28-inch-depth racks common in wall-mount or compact telecom enclosures. Rail kit weight ratings also need to be verified.
Best fit for edge data rooms and security head-end equipment closets where 6kW of always-on, zero-transfer power protection is required, the electrical infrastructure supports hardwired 208V input, and the team wants lithium-ion longevity without the maintenance overhead of lead-acid battery replacement cycles.
