Vertiv GXT5LI-8000MVRT4UXLN 8000VA Li-Ion Double-Conversion Online Rack/Tower UPS
Overview
The Vertiv GXT5LI-8000MVRT4UXLN is an 8000VA / 8000W double-conversion online UPS built around lithium-ion battery technology — a meaningful shift from sealed lead-acid in rack environments where weight, recharge speed, and long-term battery management matter. At full 8000W capacity with a 4U rack footprint (35 inches deep, 156.3 lbs), this unit targets small server rooms, network closets, and security infrastructure racks where the load demands genuine online conditioning, not standby or line-interactive approximations. It is listed under UL 1778, UL 1642, UL 1973, CSA 22.2 No. 107.3, FCC Part 15 Class A, and carries Energy Star 2.0 certification — useful checkboxes for data center compliance audits and facilities procurement.
The GXT5LI-8000MVRT4UXLN ships with a hardwired input/output configuration (L1, L2, N, G), which means this is not a plug-and-play deployment. Plan for an electrician and panel capacity before the unit arrives.
Key Features
- 8000VA / 8000W Double-Conversion Online Topology: Online double-conversion means the load never touches raw utility power — it always runs from the inverter. Voltage sags, surges, frequency deviations, and switching transients are absorbed before they reach connected equipment. For security servers, NVRs, or network infrastructure where even a sub-cycle disturbance can cause a crash or corrupt a write, this topology matters. Line-interactive UPS units do not provide this level of isolation.
- Lithium-Ion Battery Chemistry (UL 1642 / UL 1973 Listed): Li-Ion cells charge faster, tolerate more discharge cycles, and weigh significantly less than comparable lead-acid packs. In a 4U rack unit at 156.3 lbs, weight is already a factor — lead-acid at this capacity would be heavier still. Battery replacement intervals are longer, and the cells can handle higher ambient temperatures without accelerated degradation compared to VRLA. The UL 1642 and UL 1973 listings are the relevant safety certifications for Li-Ion UPS systems — not all Li-Ion UPS products carry both.
- User-Configurable Output Voltage (120V/208V or 120V/240V): Output voltage is field-configurable between 120V/208V and 120V/240V. If your load mix changes — or if you're deploying into a facility that may transition between distribution standards — you have flexibility without replacing the UPS. This is the spec to confirm with your electrical contractor before commissioning.
- 4U Rack/Tower Convertible Form Factor (6.9H × 16.9W × 35D inches): At 35 inches deep, verify your rack has adequate depth before ordering. Shallow two-post racks and some 4-post racks with cable management arms may not accommodate this unit without modification. The 6.9-inch height keeps the footprint manageable at 4U.
- Network Management via RDU101 (RJ-45) + Serial + USB: Three interface options give you flexibility: USB for direct local management, serial for legacy SNMP integrations, and the RJ-45 port for network-based monitoring via the Vertiv RDU101 card. Remote monitoring of UPS status, runtime estimates, and alarm conditions is essential in any unmanned or semi-attended equipment room. Confirm whether the RDU101 network card is included or sold separately before finalizing your order.
- Energy Star 2.0 Certified: At 8000W continuous load capacity, efficiency at partial load determines real operating cost. Energy Star 2.0 certification means the unit meets defined efficiency thresholds — relevant if your facility tracks PUE or has sustainability reporting requirements. It also simplifies procurement in government and education environments with green purchasing mandates.
- Operating Temperature Range 32°F–104°F (0°C–40°C) with 10% Derating at 50°C: The rated operating range covers standard data center and server room environments. The 10% derating at 50°C is a real-world caveat: if your equipment room runs hot — above 40°C (104°F) — you will lose capacity. Design your cooling to keep ambient below 40°C if you intend to run at full rated load.
- FCC Part 15 Class A / CSA 22.2 No. 107.3 Listed: Class A FCC certification targets commercial installations (not residential). CSA 22.2 No. 107.3 is the Canadian equivalent to UL 1778 — relevant for cross-border deployments or facilities with Canadian electrical inspection requirements.
Integration and Compatibility
The GXT5LI-8000MVRT4UXLN integrates into managed infrastructure environments via its three interface options. USB and serial connections support direct connection to servers for graceful shutdown scripting. The RJ-45 network port (RDU101) enables SNMP-based monitoring through compatible NMS platforms. The hardwired input (L1, L2, N, G) requires a dedicated circuit — this is not a C20/C14 or NEMA 5-20 connection. Factor in the appropriate breaker sizing and conduit routing for both input and output runs. Output voltage configurability (120V/208V or 120V/240V) allows the unit to serve mixed-voltage loads within the same rack, which is common in environments running both standard 120V devices and higher-density 208V server PSUs side by side.
For UPS and power protection deployments alongside rack infrastructure, pair this unit with appropriate PDUs rated for the configured output voltage. If you are building out a monitored rack environment, review the broader Vertiv power and thermal management line for compatible PDUs, rack enclosures, and environmental monitoring accessories. Buyers sourcing power protection for surveillance infrastructure may also want to review network video recorders and associated rack equipment to size runtime requirements accurately before specifying this UPS. For guidance on selecting the right UPS capacity for your load, the UPS selection guide covers topology comparisons and runtime estimation methodology. If you're building a complete rack solution, rack enclosures and accessories should be confirmed for depth compatibility with this 35-inch unit before purchasing.
Frequently Asked Questions
Q: What is the difference between the GXT5LI-8000MVRT4UXLN and a standard GXT5 model without the LI designation?
A: The LI designation indicates lithium-ion battery chemistry rather than sealed lead-acid (VRLA). Li-Ion offers faster recharge times, longer cycle life, lighter weight for equivalent capacity, and better performance at elevated temperatures. The unit also carries UL 1642 (Li-Ion cell) and UL 1973 (Li-Ion battery pack with UPS) listings — safety certifications specific to Li-Ion UPS systems.
Q: Is the GXT5LI-8000MVRT4UXLN hardwired, or does it use a standard power cord?
A: It is hardwired (L1, L2, N, G) on both input and output. There is no standard plug. Installation requires a licensed electrician and a dedicated circuit. Factor this into your project timeline and budget before ordering.
Q: Can the output voltage be changed after installation?
A: Yes. Output voltage is user-configurable between 120V/208V and 120V/240V. However, changing the output voltage after initial installation will require verifying that all connected loads and PDUs are rated for the new configuration. Consult your electrician before reconfiguring a live installation.
Q: Does the GXT5LI-8000MVRT4UXLN include a network management card?
A: The unit includes an RJ-45 network port for the RDU101 network management card. Confirm with your supplier whether the RDU101 card is included in the base configuration or is a separately ordered accessory before finalizing your purchase.
Q: What is the operating temperature limit, and is there a derating condition?
A: The rated operating range is 32°F to 104°F (0°C to 40°C). At 50°C (122°F), a 10% capacity derating applies. If your equipment room ambient exceeds 40°C, you will not get full rated output — size your cooling accordingly or derate your load expectations.
Q: Is the GXT5LI-8000MVRT4UXLN Energy Star certified?
A: Yes. It carries Energy Star 2.0 certification, which confirms it meets efficiency thresholds at defined load levels. This is relevant for facilities with green procurement policies or PUE tracking requirements.
The GXT5LI-8000MVRT4UXLN is the unit I'd specify when a customer needs genuine online isolation at 8000W and doesn't want to manage lead-acid battery replacements every 3–5 years. The Li-Ion chemistry — listed under both UL 1642 and UL 1973 — is the right call for a rack that doesn't get walked daily, because the battery management is more forgiving and the recharge cycle is faster after an extended outage. At 156.3 lbs in a 4U chassis, it's heavy but manageable with two people and a proper rack rail kit.
Technical Highlights:
- Double-Conversion Online Topology: The load runs from the inverter at all times — not from the utility with a battery backup on standby. For NVRs recording to disk or network switches handling video streams, this eliminates the sub-cycle transfer gap that line-interactive units have. It matters when you're recording evidence-grade footage and can't afford a frame drop from a voltage event.
- User-Configurable Output (120V/208V or 120V/240V): Field-configurable output voltage means you can serve a mixed rack — 208V server PSUs and 120V ancillary devices — without a separate transformer. Confirm your PDU ratings before you switch modes post-install.
- Energy Star 2.0 + FCC Part 15 Class A: The efficiency certification simplifies procurement in government and education accounts. Class A FCC is the commercial-environment rating — residential Class B UPS units are not appropriate for data center or security operations center deployments.
Deployment Considerations:
- The hardwired L1/L2/N/G termination is the single biggest project-planning item. Budget for electrician time and a dedicated 60A+ circuit (verify with your electrical contractor for the specific breaker sizing at your configured voltage). Don't assume the unit ships with any cable — it doesn't.
- At 35 inches of depth, measure your rack before ordering. Many 4-post racks with rear cable management panels or brush strips reduce usable depth to under 32 inches. The unit will not fit in a shallow open-frame 2-post rack without proper mounting rails.
This unit is the right fit for a security operations center or mid-size server room running a mix of 120V/208V loads — NVRs, core switches, access control servers — where the operator wants online conditioning, remote monitoring via the RDU101 interface, and a battery chemistry that doesn't require annual capacity testing to catch failing cells before they fail on a weekend.
