APC by Schneider Electric SRTL8KRM4UT-5KTF vs Vertiv GXT5-8000HVRT5UXLN: Specification Comparison
Both the APC Smart-UPS Ultra Li-ion SRTL8KRM4UT-5KTF and the Vertiv GXT5 GXT5-8000HVRT5UXLN are 8 kVA, 208 V rack-mountable online double-conversion UPS units aimed at data centers, server rooms, and critical infrastructure environments. The APC unit adds an integrated 5 kVA step-down transformer for 120 V load compatibility, and uses lithium-ion battery chemistry. The Vertiv unit is a pure 208 V hardwired system with a factory-installed SNMP/web card. This comparison evaluates power and load handling, physical and environmental characteristics, and management and interface capabilities.

How do power capacity, output flexibility, and wiring differ between these two units?
Both units are rated at 8,000 VA. The Vertiv GXT5-8000HVRT5UXLN is specified at 8,000 W (1.0 power factor), while the power factor and wattage output of the SRTL8KRM4UT-5KTF are not stated in the provided specifications.
The Vertiv outputs 200/208/220/230/240 VAC (user-configurable) via hardwired connections, plus 2 × L6-20R and 2 × L6-30R receptacles. The APC unit's outlet configuration and output voltage options are not provided in the supplied specifications.
The SRTL8KRM4UT-5KTF includes an integrated 5 kVA step-down transformer, which allows it to drive 120 V loads directly from a 208 V input — a meaningful differentiator for mixed-voltage environments. The Vertiv GXT5-8000HVRT5UXLN has no transformer component listed in its specifications.
Input voltage range for the Vertiv is 176–288 VAC around a 208 VAC nominal. The APC's input voltage range is not specified in the provided data.
How do battery technology, physical footprint, and weight compare?
The APC SRTL8KRM4UT-5KTF uses lithium-ion battery chemistry. Lithium-ion generally offers a longer service life and lower weight per unit of stored energy compared to VRLA lead-acid, and typically requires less maintenance. No weight or physical dimensions are provided for the APC unit in the supplied specifications.
The Vertiv GXT5-8000HVRT5UXLN does not specify its battery chemistry in the provided data. Its physical dimensions are 8.5 in H × 16.9 in W × 24.8 in D, and it weighs 164.2 lb. Rack unit height is not explicitly stated but can be inferred at approximately 5U based on the 8.5 in height.
Because dimensions and weight for the APC unit are absent from the provided specifications, a direct physical footprint comparison cannot be made. Buyers with constrained rack space or floor-load limits should obtain APC's published dimensional data before finalizing selection.
Which unit offers stronger remote management, efficiency ratings, and certifications?
The Vertiv GXT5-8000HVRT5UXLN ships with a factory pre-installed Vertiv RDU101 SNMP/web card, providing SNMP, web management, USB, RS485, RS232, a terminal block, and an external battery connector out of the box. The control panel is a full-color graphic LCD with gravity-sensing orientation. Protocols supported include SNMP and web management, plus serial for out-of-band access.
The APC SRTL8KRM4UT-5KTF's management interfaces, SNMP capability, and software features are not described in the provided specifications. APC UPS products in this class commonly support network management cards, but no such detail can be confirmed from the data supplied.
The Vertiv unit achieves up to 98% efficiency in Active ECO mode and up to 95% in on-line mode, and carries ENERGY STAR 2.0, UL1778, c-UL, RoHS2, and REACH certifications. Efficiency ratings and certifications for the APC unit are not present in the supplied specifications.
The Vertiv's topology is explicitly stated as on-line double conversion with flexible rack/tower form factor. The APC unit's topology is not confirmed in the provided data, though the product class and name suggest a similar online architecture.
Which should you choose: the SRTL8KRM4UT-5KTF or the GXT5-8000HVRT5UXLN?
Our take: The GXT5-8000HVRT5UXLN is the stronger choice when verified efficiency figures, out-of-box SNMP management, and a fully documented physical footprint are required at the point of procurement. The Vertiv specifies a 1.0 power factor (8,000 VA / 8,000 W), up to 98% efficiency in ECO mode, and ships with a factory RDU101 SNMP/web card — none of those three attributes are confirmed in the APC data provided. Conversely, the SRTL8KRM4UT-5KTF's integrated 5 kVA step-down transformer is a decisive advantage in mixed 208 V / 120 V environments, eliminating the cost and rack space of a separate transformer. Its lithium-ion chemistry also offers a longer expected service life than the Vertiv's unspecified battery type. Buyers running pure 208 V loads in a managed data center should lean toward the Vertiv for its documented efficiency and included management card; buyers powering 120 V equipment off a 208 V feed should evaluate the APC's transformer-inclusive design against the full published specification sheet.

Frequently Asked Questions
Which should you choose: the SRTL8KRM4UT-5KTF or the GXT5-8000HVRT5UXLN?
The GXT5-8000HVRT5UXLN is the stronger choice when verified efficiency figures, out-of-box SNMP management, and a fully documented physical footprint are required at the point of procurement. The Vertiv specifies a 1.0 power factor (8,000 VA / 8,000 W), up to 98% efficiency in ECO mode, and ships with a factory RDU101 SNMP/web card — none of those three attributes are confirmed in the APC data provided. Conversely, the SRTL8KRM4UT-5KTF's integrated 5 kVA step-down transformer is a decisive advantage in mixed 208 V / 120 V environments, eliminating the cost and rack space of a separate transformer. Its lithium-ion chemistry also offers a longer expected service life than the Vertiv's unspecified battery type. Buyers running pure 208 V loads in a managed data center should lean toward the Vertiv for its documented efficiency and included management card; buyers powering 120 V equipment off a 208 V feed should evaluate the APC's transformer-inclusive design against the full published specification sheet.
Does either UPS include a network management card in the box?
The Vertiv GXT5-8000HVRT5UXLN ships with a factory pre-installed Vertiv RDU101 SNMP/web card included as standard. The APC SRTL8KRM4UT-5KTF's management card options are not described in the specifications provided, so buyers should confirm with APC whether a network management card is included or must be purchased separately.
Which unit is better if I need to power both 208 V and 120 V equipment from the same UPS?
The APC SRTL8KRM4UT-5KTF includes an integrated 5 kVA step-down transformer, which is explicitly designed to support 120 V loads fed from a 208 V input. The Vertiv GXT5-8000HVRT5UXLN lists no transformer in its specifications, making it suited to 208 V loads only unless an external step-down transformer is added.
How do the two units compare on efficiency, and does either carry an ENERGY STAR rating?
The Vertiv GXT5-8000HVRT5UXLN is rated at up to 98% efficiency in Active ECO mode and up to 95% in on-line mode, and holds an ENERGY STAR 2.0 certification. Efficiency figures and ENERGY STAR status for the APC SRTL8KRM4UT-5KTF are not present in the specifications provided; buyers should consult APC's published datasheet for those values before making an energy-cost comparison.
