Vertiv GXT5-6000RT208 vs Vertiv GXT5LI-6000MVRT3UXLN: Specification Comparison
Both the GXT5-6000RT208 and GXT5LI-6000MVRT3UXLN are Vertiv GXT5-series 6000VA rack/tower double-conversion online UPS units targeting data centers, network closets, and critical infrastructure requiring hardwired 208V output. The primary differentiator is battery chemistry: the GXT5-6000RT208 ships with compatibility for pre-installed GXT3/GXT4 VRLA battery pods, while the GXT5LI-6000MVRT3UXLN is a lithium-ion (LI) variant. This comparison examines power architecture, physical and environmental specs, and compliance and interface capabilities across both units.

How do the power ratings, input/output voltage ranges, and wiring configurations compare between these two 6000VA UPS units?
Both units share a 6000VA / 6000W power rating at their primary 6000VA configuration. However, the spec data for the GXT5-6000RT208 is presented as a model-family table spanning 3000VA through 20000VA and does not isolate confirmed input/output voltage ranges or wiring specifics for the 6000VA SKU itself — those details are absent from the provided spec set.
The GXT5LI-6000MVRT3UXLN specifies an input voltage range of 120V/240V and an output voltage range of 120V/208V, with 120V/240V user-configurable output. Wiring is hardwired (L1, L2, N, G). The GXT5-6000RT208 listing references 208V hardwire in its product name but no explicit input voltage range, output configurability, or wiring terminal detail is present in the provided specs.
For installers requiring confirmed output voltage flexibility, the GXT5LI-6000MVRT3UXLN is the only unit here with documented user-configurable output (120V/240V). Buyers evaluating the GXT5-6000RT208 for specific input/output voltage compatibility should consult the Vertiv datasheet directly, as those specs are not present in the data provided.
What are the physical dimensions, weight, and operating temperature envelope for each unit?
The GXT5LI-6000MVRT3UXLN publishes full dimensional and weight specs: 5.2 in H × 16.9 in W × 35 in D, 100 lbs, with an operating temperature range of 32°F to 104°F (0°C to 40°C), with a 10% derating noted at 50°C.
The GXT5-6000RT208 provides no dimensional, weight, or operating temperature data in the supplied specifications. Rack unit height, depth, and enclosure weight are all absent, making direct physical comparison impossible from the provided data alone.
For pre-installation planning — cabinet space allocation, floor loading, and HVAC headroom — the GXT5LI-6000MVRT3UXLN is the only unit with confirmed specs. The GXT5-6000RT208 would require the installer to source physical specs directly from Vertiv before rack planning.
How do safety certifications, regulatory listings, and management interface options compare between the two units?
The GXT5LI-6000MVRT3UXLN carries a detailed listing set: UL 1642 (Li-Ion Battery Cells), UL 1973 (Li-Ion Battery Pack w/UPS), UL 1778, CSA 22.2 No. 107.3, c-UL, FCC Part 15 Class A, and Energy Star 2.0. The lithium-ion certifications (UL 1642, UL 1973) are specific to its Li-Ion chemistry and are relevant for data center operators subject to fire codes or insurance requirements governing Li-Ion installations.
The GXT5-6000RT208 has no safety listings, regulatory certifications, or compliance data present in the provided specifications. Whether it carries UL 1778 or FCC Part 15 cannot be confirmed from the data supplied.
Interface options for the GXT5LI-6000MVRT3UXLN are specified as Serial Port, Network RJ-45 (RDU101), and USB. The GXT5-6000RT208 lists no interface or management connectivity data. For IT buyers requiring network-managed UPS capability with a known card interface, the GXT5LI-6000MVRT3UXLN is the only unit with documented remote management support in this comparison.
Which should you choose: the GXT5-6000RT208 or the GXT5LI-6000MVRT3UXLN?
Our take: The GXT5LI-6000MVRT3UXLN is the stronger documented choice when spec transparency, lithium-ion battery chemistry, and confirmed management interfaces are decision factors. Three concrete spec deltas stand out: first, the GXT5LI-6000MVRT3UXLN provides a fully specified physical footprint (5.2 in H × 16.9 in W × 35 in D, 100 lbs) while the GXT5-6000RT208 supplies none; second, the LI unit documents user-configurable output (120V/208V or 120V/240V hardwired) versus no confirmed output spec for the RT208; third, the LI unit carries seven safety and regulatory listings including Li-Ion-specific UL 1642 and UL 1973, plus Energy Star 2.0, while the RT208 has no listed certifications in the provided data. The GXT5-6000RT208 may suit sites with existing GXT3/GXT4 battery pod infrastructure, but buyers cannot confirm its electrical or physical specs from the data provided here and must consult Vertiv directly before specifying it.

Frequently Asked Questions
Which should you choose: the GXT5-6000RT208 or the GXT5LI-6000MVRT3UXLN?
The GXT5LI-6000MVRT3UXLN is the stronger documented choice when spec transparency, lithium-ion battery chemistry, and confirmed management interfaces are decision factors. Three concrete spec deltas stand out: first, the GXT5LI-6000MVRT3UXLN provides a fully specified physical footprint (5.2 in H × 16.9 in W × 35 in D, 100 lbs) while the GXT5-6000RT208 supplies none; second, the LI unit documents user-configurable output (120V/208V or 120V/240V hardwired) versus no confirmed output spec for the RT208; third, the LI unit carries seven safety and regulatory listings including Li-Ion-specific UL 1642 and UL 1973, plus Energy Star 2.0, while the RT208 has no listed certifications in the provided data. The GXT5-6000RT208 may suit sites with existing GXT3/GXT4 battery pod infrastructure, but buyers cannot confirm its electrical or physical specs from the data provided here and must consult Vertiv directly before specifying it.
Is the GXT5LI-6000MVRT3UXLN or the GXT5-6000RT208 better suited for a new rack installation where I need confirmed dimensions and weight?
The GXT5LI-6000MVRT3UXLN is the only unit with confirmed physical specs in the provided data: 5.2 in H, 16.9 in W, 35 in D, 100 lbs. The GXT5-6000RT208 has no dimensional or weight data present in the supplied specifications, so rack space planning and floor-load calculations cannot be completed from this data alone.
Does either UPS support network management, and which interface options are confirmed?
Only the GXT5LI-6000MVRT3UXLN has documented interface options: Serial Port, Network RJ-45 (RDU101), and USB. The GXT5-6000RT208 lists no interface or connectivity data in the provided specifications. Buyers requiring confirmed network-managed UPS capability should note this distinction.
Are there fire code or insurance compliance differences between a lithium-ion and a VRLA-based UPS at this power level?
The GXT5LI-6000MVRT3UXLN carries UL 1642 (Li-Ion Battery Cells) and UL 1973 (Li-Ion Battery Pack w/UPS) certifications specific to its lithium-ion chemistry, which are increasingly required by AHJs and insurers for Li-Ion UPS installations. The GXT5-6000RT208 has no safety listings confirmed in the provided specs. Sites with strict fire code requirements for Li-Ion should verify local AHJ acceptance of these certifications; sites preferring traditional VRLA chemistry may find the RT208 relevant but must source its compliance listings from Vertiv directly.
