How do power capacity, efficiency, and topology compare between the SRTL8KRM4UT-5KTF and GXT5-8000MVRT6UXLN?
The Vertiv GXT5-8000MVRT6UXLN is specified at 8,000 VA / 8,000 W with a unity (1.0) power factor, operating on-line double-conversion topology. Input voltage is nominally 208 VAC with an accepted range of 176–280 VAC. Output is user-configurable at 208 VAC or 120 VAC. Efficiency reaches up to 98% in Active ECO Mode and up to 95% in standard on-line mode, and the unit carries ENERGY STAR 2.0 certification.
For the APC SRTL8KRM4UT-5KTF, the product name references 8 kVA / 208 V and includes a bundled 5 kVA step-down transformer, suggesting a stepped output capability for 120 V loads. However, the supplied data contains no verified figures for topology, efficiency, input voltage range, output voltage range, or power factor. The Li-Ion battery type is referenced in marketing copy, and the 5KTF suffix indicates the step-down transformer accessory is factory-bundled. No certifications are listed in the supplied spec data.
Buyers requiring documented efficiency ratings or certified topology specifications can confirm those figures only for the Vertiv unit from the data provided here.
How do the physical footprint, weight, and operating environment specifications differ?
The Vertiv GXT5-8000MVRT6UXLN occupies a 6U rack space with published dimensions of 10.2 in (H) × 16.9 in (W) × 25.6 in (D) and a shipping weight of 224.8 lb. Operating temperature is rated +32 to +104 °F (0 to 40 °C). The unit supports a flexible rack/tower form factor. Wiring is hardwired in and out, with optional Power Output Distribution (POD) modules available.
No physical dimensions, rack unit height, weight, or operating temperature range are provided in the APC SRTL8KRM4UT-5KTF spec data supplied. The product name indicates a rack-mount form factor (RM) and 4U chassis (4U in the model string), and marketing copy references Li-Ion chemistry — which typically reduces weight versus lead-acid equivalents — but no specific weight figure is available to confirm.
For space-constrained deployments where rack unit count, depth, and weight distribution are planning inputs, only the Vertiv unit provides the necessary physical data from the specifications supplied.
What management interfaces and monitoring protocols does each UPS support?
The Vertiv GXT5-8000MVRT6UXLN ships with a factory pre-installed Vertiv RDU101 SNMP/Webcard, enabling SNMP and web-based management out of the box. Additional interfaces include USB, RS-485, RS-232, a terminal block, and an external battery connector. A full-color graphic LCD with gravity-sensing orientation is standard on the control panel. Serial connection supports out-of-band management. Protocols include SNMP and web management enabled by default from factory.
The APC SRTL8KRM4UT-5KTF spec data references 'Remote Connectivity' only in a marketing context (keeping routers and modems powered) and mentions 'PowerChute or similar software for automatic shutdown and monitoring' generically. No specific network card model, included vs. optional status, protocol list (SNMP version, Modbus, etc.), or interface port inventory is specified in the supplied data.
Installers integrating UPS units into a BMS, DCIM, or NMS platform should verify APC's network management card inclusion and protocol support directly with APC specification sheets, as that detail is absent from the data provided.
Which should you choose: the SRTL8KRM4UT-5KTF or the GXT5-8000MVRT6UXLN?
Our take: The GXT5-8000MVRT6UXLN is the stronger choice when a verified, spec-driven procurement decision is required at the time of evaluation. The Vertiv unit provides a complete, auditable specification set: 8,000 VA / 8,000 W at unity power factor, up to 98% efficiency in ECO Mode, ENERGY STAR 2.0 certification, factory-included RDU101 SNMP/Webcard, documented dimensions of 10.2 × 16.9 × 25.6 in at 224.8 lb, and a 176–280 VAC input range — all confirmed from the supplied data. The APC SRTL8KRM4UT-5KTF offers a potentially compelling differentiator in its Li-Ion battery chemistry and bundled 5 kVA step-down transformer for mixed 208/120 V loads, but no hard specifications for efficiency, weight, topology, interfaces, or certifications are present in the supplied data to substantiate a side-by-side numeric comparison. Buyers with a 208 V infrastructure requiring confirmed efficiency figures and out-of-box network management should specify the Vertiv; buyers prioritizing Li-Ion battery life and a factory-bundled step-down transformer should obtain APC's full datasheet before finalizing.

Frequently Asked Questions
Which should you choose: the SRTL8KRM4UT-5KTF or the GXT5-8000MVRT6UXLN?
The GXT5-8000MVRT6UXLN is the stronger choice when a verified, spec-driven procurement decision is required at the time of evaluation. The Vertiv unit provides a complete, auditable specification set: 8,000 VA / 8,000 W at unity power factor, up to 98% efficiency in ECO Mode, ENERGY STAR 2.0 certification, factory-included RDU101 SNMP/Webcard, documented dimensions of 10.2 × 16.9 × 25.6 in at 224.8 lb, and a 176–280 VAC input range — all confirmed from the supplied data. The APC SRTL8KRM4UT-5KTF offers a potentially compelling differentiator in its Li-Ion battery chemistry and bundled 5 kVA step-down transformer for mixed 208/120 V loads, but no hard specifications for efficiency, weight, topology, interfaces, or certifications are present in the supplied data to substantiate a side-by-side numeric comparison. Buyers with a 208 V infrastructure requiring confirmed efficiency figures and out-of-box network management should specify the Vertiv; buyers prioritizing Li-Ion battery life and a factory-bundled step-down transformer should obtain APC's full datasheet before finalizing.
Is the SRTL8KRM4UT-5KTF or GXT5-8000MVRT6UXLN better for a mixed 208 V / 120 V server room?
The SRTL8KRM4UT-5KTF includes a bundled 5 kVA step-down transformer (indicated by the -5KTF suffix), which is designed to serve 120 V loads from a 208 V UPS — a relevant feature for mixed-voltage environments. The GXT5-8000MVRT6UXLN supports user-configurable output of 208 VAC or 120 VAC per its specifications. However, no output outlet configuration or receptacle count is confirmed in the supplied data for either unit; buyers should verify per-circuit capacity and outlet breakdowns with each manufacturer's datasheet before specifying.
Does the GXT5-8000MVRT6UXLN include a network management card, or is it an add-on?
Per the supplied specifications, the GXT5-8000MVRT6UXLN ships with the Vertiv RDU101 SNMP/Webcard factory pre-installed. SNMP and web management are enabled out of the box. No additional purchase is required for basic network monitoring and management. The APC SRTL8KRM4UT-5KTF spec data does not confirm whether a network management card is included or optional.
How does battery type affect the long-term operating cost of these two UPS systems?
The APC SRTL8KRM4UT-5KTF marketing copy references Li-Ion battery chemistry, which typically offers longer cycle life and lower replacement frequency compared to VRLA lead-acid batteries. No battery specifications (capacity, runtime, replacement interval, or warranty) are confirmed in the supplied APC data. The Vertiv GXT5-8000MVRT6UXLN spec data does not specify battery chemistry in the supplied information. Buyers should request battery replacement cost, cycle life ratings, and warranty terms from both manufacturers before making a total-cost-of-ownership comparison.
