How do the input/output voltage ranges and electrical specifications compare?
The SRT6KRMXLI is designed for 230V-centric markets with an input voltage range of 100–275V, an output range of 220–240V, and frequency acceptance of 40–70Hz. It delivers 6000VA / 6000W with a pure sine waveform, a 3:1 crest factor, and an efficiency rating of 94.4%. Surge protection is included with a rated surge energy absorption of 480J.
The GXT5LI-6000MVRT3UXLN targets North American infrastructure with an input voltage range of 120V/240V and a user-configurable output of 120V/208V or 120V/240V. Its power rating is equally 6000VA / 6000W. Efficiency, crest factor, surge energy rating, input frequency range, and waveform type are not stated in the provided specifications.
Buyers must select based on site voltage: the SRT6KRMXLI is the correct choice for 230V single-phase environments, while the GXT5LI-6000MVRT3UXLN serves North American 208V three-wire or 120/240V split-phase sites. The APC unit provides a confirmed 94.4% efficiency figure; no equivalent figure is available for the Vertiv unit from the provided specs.
What are the battery technology, interface options, and compliance certifications for each unit?
The GXT5LI-6000MVRT3UXLN uses a lithium-ion battery pack, as evidenced by its UL 1642 (Li-Ion Battery Cells) and UL 1973 (Li-Ion Battery Pack w/UPS) certifications. Lithium-ion batteries generally offer longer cycle life and lower weight-per-capacity than traditional VRLA alternatives. The unit connects via a hardwired input (L1, L2, N, G) and provides Serial Port, Network RJ-45 (RDU101), and USB interface options. It carries UL 1778, CSA 22.2 No. 107.3, c-UL, FCC Part 15 Class A, and Energy Star 2.0 certifications.
Battery chemistry for the SRT6KRMXLI is not specified in the provided data. Interface options, connectivity ports, and compliance certifications for the SRT6KRMXLI are also not included in the provided specifications. The APC unit does confirm Emergency Power Off (EPO) support and audible alarms, neither of which is confirmed or denied for the Vertiv unit in the provided specs.
Buyers who require lithium-ion longevity, network manageability via RJ-45, or Energy Star 2.0 compliance can confirm those features only for the GXT5LI-6000MVRT3UXLN from the available data. EPO capability is confirmed only for the SRT6KRMXLI.
How do the physical dimensions, weight, noise, and operating environment compare?
The GXT5LI-6000MVRT3UXLN has fully documented physical specifications: 5.2 in H × 16.9 in W × 35 in D, weighing 100 lbs, and rated for operation from 32°F to 104°F (0°C to 40°C) with a 10% derating noted at 50°C. These figures allow precise rack space and floor-load planning.
Physical dimensions and weight for the SRT6KRMXLI are not provided in the available specifications. The SRT6KRMXLI does specify a noise level of 55 dB, which is relevant in noise-sensitive environments such as offices or co-location facilities. No noise level figure is provided for the GXT5LI-6000MVRT3UXLN.
Installers needing to confirm rack-unit height, depth clearance, or structural load ratings can do so only for the GXT5LI-6000MVRT3UXLN from the provided data. Conversely, acoustic planning for data rooms or office-adjacent closets can be informed only by the SRT6KRMXLI's published 55 dB noise rating. Operating temperature data is confirmed only for the Vertiv unit.
Which should you choose: the SRT6KRMXLI or the GXT5LI-6000MVRT3UXLN?
Our take: The SRT6KRMXLI is the stronger choice when the deployment site runs on 230V single-phase power and acoustic performance or EPO integration is a priority, while the GXT5LI-6000MVRT3UXLN is the correct selection for North American 208V or 120/240V infrastructure requiring lithium-ion battery longevity, network management, and verified Energy Star 2.0 compliance. Key spec deltas: (1) voltage ecosystem — APC covers 100–275V input / 220–240V output versus Vertiv's 120V/240V input / 120V/208V or 120V/240V configurable output; (2) battery chemistry — Vertiv is confirmed Li-Ion (UL 1642/1973 certified), APC battery type is unspecified in provided data; (3) efficiency — APC publishes 94.4%, Vertiv's efficiency is not stated in the provided specs. Platform qualifier: neither unit should be cross-deployed into the other's voltage region without transformer infrastructure.

Frequently Asked Questions
Which should you choose: the SRT6KRMXLI or the GXT5LI-6000MVRT3UXLN?
The SRT6KRMXLI is the stronger choice when the deployment site runs on 230V single-phase power and acoustic performance or EPO integration is a priority, while the GXT5LI-6000MVRT3UXLN is the correct selection for North American 208V or 120/240V infrastructure requiring lithium-ion battery longevity, network management, and verified Energy Star 2.0 compliance. Key spec deltas: (1) voltage ecosystem — APC covers 100–275V input / 220–240V output versus Vertiv's 120V/240V input / 120V/208V or 120V/240V configurable output; (2) battery chemistry — Vertiv is confirmed Li-Ion (UL 1642/1973 certified), APC battery type is unspecified in provided data; (3) efficiency — APC publishes 94.4%, Vertiv's efficiency is not stated in the provided specs. Platform qualifier: neither unit should be cross-deployed into the other's voltage region without transformer infrastructure.
Can I use the SRT6KRMXLI or GXT5LI-6000MVRT3UXLN in a North American 208V data center rack?
Only the GXT5LI-6000MVRT3UXLN is specified for North American voltages (120V/208V or 120V/240V). The SRT6KRMXLI is specified for 220–240V output and is designed for 230V-centric markets; using it on a North American 208V feed would require verification of compatibility not confirmed by the provided specs. The GXT5LI-6000MVRT3UXLN is the appropriate choice for that environment.
Which unit offers better remote monitoring and management capabilities?
The GXT5LI-6000MVRT3UXLN lists Serial Port, Network RJ-45 (RDU101), and USB interfaces in its specifications, enabling network-based UPS monitoring. The SRT6KRMXLI's interface and connectivity options are not included in the provided specifications, so a direct comparison cannot be made from available data alone. Buyers requiring confirmed network management should verify SRT6KRMXLI connectivity through APC's full datasheet.
Is the GXT5LI-6000MVRT3UXLN's lithium-ion battery a meaningful advantage over the SRT6KRMXLI?
Based on provided specifications, the GXT5LI-6000MVRT3UXLN is confirmed to use a lithium-ion battery pack (certified to UL 1642 and UL 1973), which typically offers longer cycle life and lower weight compared to traditional VRLA batteries. The SRT6KRMXLI's battery chemistry is not stated in the provided specifications, so a direct battery-technology comparison cannot be drawn from available data. Buyers for whom Li-Ion longevity is a decision factor can confirm that feature only for the Vertiv unit.
