How do output capacity, receptacle mix, and wattage compare between the two units?
The APC SRT5KRMXLT-5KTF is rated at 5000VA with an input of 208V AC (1-phase) and includes an integrated step-down transformer delivering 120V output. Its output receptacle array is notably broad: 12 NEMA 5-20R, 2 NEMA L6-20R, and 2 NEMA L6-30R outlets, giving installers flexibility across standard 20A, 20A locking, and 30A locking circuit requirements in a mixed-load environment. APC does not publish a watts (W) figure in the provided specs; the VA rating alone is listed.
The Vertiv GXT5LI-5000MVRT3UXLN is rated at 5000VA and 5000W explicitly, implying a unity (1.0) power factor—a meaningful spec for loads with high power factor demand. Its output voltage is configurable: 120V/208V or 120V/240V per user setting. Input wiring is via a single NEMA L14-30P plug. Specific output receptacle counts and types are not listed in the provided specs. The absence of a dedicated step-down transformer is implied by the configurable output, but the internal architecture for voltage conversion is not detailed in the supplied data.
How do battery chemistry, form factor, weight, and physical footprint differ?
The APC SRT5KRMXLT-5KTF uses a conventional lead-acid battery and occupies 5U of rack space. Its physical dimensions are 8.58 in H × 17.01 in W × 28.31 in D (218 × 432 × 719 mm), and it weighs 217.99 lb (98.88 kg). The substantial weight is consistent with lead-acid chemistry at this VA class and must be factored into rack load ratings and floor loading. APC provides a 24-month battery warranty and a 36-month UPS warranty. Surge energy absorption is rated at 480 J.
The Vertiv GXT5LI-5000MVRT3UXLN uses lithium-ion (Li-Ion) battery chemistry, reflected in its UL 1642 and UL 1973 listings for Li-Ion cells and packs. It occupies 3U (implied by the 'RT3U' model designation and the 5.2 in height) and weighs 104.9 lb—less than half the APC unit's weight. Dimensions are 5.2 in H × 16.9 in W × 35 in D. Li-Ion chemistry typically offers longer cycle life, faster recharge, and a smaller thermal footprint than lead-acid, though the operating temperature ceiling of 104°F (40°C) with derating at 50°C is noted. No surge energy rating or battery/unit warranty terms are present in the provided specs for the Vertiv.
What network management interfaces and safety certifications does each unit carry?
The APC SRT5KRMXLT-5KTF provides a 10/100 BaseT network connection for remote monitoring and management. No specific management protocol (SNMP card model, software platform) is named in the provided specs. No safety certification listings are present in the provided APC specs.
The Vertiv GXT5LI-5000MVRT3UXLN lists three interface options: Serial Port, Network RJ-45 (identified as RDU101—Vertiv's Remote Display Unit), and USB. This trio covers legacy serial integration, IP-based network management via the RDU101 module, and local USB connectivity. On compliance, the Vertiv carries a robust certification set: UL 1778 (UPS), UL 1642 (Li-Ion cells), UL 1973 (Li-Ion battery pack with UPS), CSA 22.2 No. 107.3, c-UL, FCC Part 15 Class A, and Energy Star 2.0. The Energy Star 2.0 listing is notable for facilities with energy-efficiency mandates or green building targets. APC certification listings are not provided in the supplied specs.
Which should you choose: the SRT5KRMXLT-5KTF or the GXT5LI-5000MVRT3UXLN?
Our take: The SRT5KRMXLT-5KTF is the stronger choice when the installation requires a broad, mixed-receptacle output array and a longer combined warranty at the 5000VA online tier. It delivers 12 NEMA 5-20R plus four locking outlets and carries a 36-month UPS / 24-month battery warranty, neither of which is documented for the Vertiv in the provided specs. However, the GXT5LI-5000MVRT3UXLN holds decisive advantages in three areas: it weighs 104.9 lb versus 217.99 lb for the APC—a 113 lb difference that materially affects rack load planning—it specifies an explicit 5000W output at unity power factor, and it holds Energy Star 2.0 certification alongside a fuller UL/CSA compliance portfolio. Its Li-Ion chemistry also implies longer service life between battery replacements. Buyers in facilities with strict weight limits, energy-efficiency requirements, or high-power-factor server loads should favor the Vertiv; those needing maximum receptacle variety and documented warranty terms should favor the APC.

Frequently Asked Questions
Which should you choose: the SRT5KRMXLT-5KTF or the GXT5LI-5000MVRT3UXLN?
The SRT5KRMXLT-5KTF is the stronger choice when the installation requires a broad, mixed-receptacle output array and a longer combined warranty at the 5000VA online tier. It delivers 12 NEMA 5-20R plus four locking outlets and carries a 36-month UPS / 24-month battery warranty, neither of which is documented for the Vertiv in the provided specs. However, the GXT5LI-5000MVRT3UXLN holds decisive advantages in three areas: it weighs 104.9 lb versus 217.99 lb for the APC—a 113 lb difference that materially affects rack load planning—it specifies an explicit 5000W output at unity power factor, and it holds Energy Star 2.0 certification alongside a fuller UL/CSA compliance portfolio. Its Li-Ion chemistry also implies longer service life between battery replacements. Buyers in facilities with strict weight limits, energy-efficiency requirements, or high-power-factor server loads should favor the Vertiv; those needing maximum receptacle variety and documented warranty terms should favor the APC.
Is the SRT5KRMXLT-5KTF or GXT5LI-5000MVRT3UXLN better for a rack already near its weight limit?
The Vertiv GXT5LI-5000MVRT3UXLN is significantly lighter at 104.9 lb versus 217.99 lb for the APC SRT5KRMXLT-5KTF—a difference of over 113 lb. If your rack is approaching its rated load capacity, the Vertiv's lithium-ion chemistry provides a major weight advantage. The APC's lead-acid battery is the primary driver of its heavier weight and should be evaluated against your rack's floor and rail load ratings before installation.
Which unit is better suited if I need to power a mix of 120V standard and 120V/208V locking receptacle loads?
The APC SRT5KRMXLT-5KTF specifies its output receptacle mix explicitly: 12 NEMA 5-20R, 2 NEMA L6-20R, and 2 NEMA L6-30R. This makes it well-suited for environments with diverse standard and locking outlet requirements. The Vertiv GXT5LI-5000MVRT3UXLN's output receptacle types and counts are not listed in the provided specs, so direct comparison on this dimension is not possible from the available data.
Does either UPS carry Energy Star certification, and does that matter for my facility?
Only the Vertiv GXT5LI-5000MVRT3UXLN carries Energy Star 2.0 certification, as listed in its provided specs. Energy Star compliance may be required for certain government contracts, green building (LEED) credits, or utility rebate programs. The APC SRT5KRMXLT-5KTF's energy certifications are not included in the provided specs, so no claim can be made about its Energy Star status from the available data.
