Compare like-for-like specifications
Start with topology, rated kW, input and output phase, overload capability and the supported battery arrangement. Two models close in nominal capacity can differ meaningfully in their intended application.
The Powermode catalogue includes Q-on I-Series 5kVA packages with Freedom Won eTower storage and a Q-on S-Series 6kVA online UPS. The S-Series 6kVA lists a 0.9 output power factor, equivalent to 5.4kW rated output. Confirm the exact I-Series model's kW limit in the quotation.
Look at the load at its busiest
A small office or network room may sit comfortably within 5kVA during normal operation but approach its limit after additional equipment is installed. Measure the critical circuit and list planned expansion before choosing.
Do not select either option solely by counting computers. Servers, networking equipment, storage and specialist electronics have different demand profiles. Loads with substantial starting current may require a different design altogether.
The battery package determines autonomy
Powermode's I-Series listings include 5kWh, 10kWh and 15kWh nominal eTower package options. Those energy figures describe different battery capacities; they are not promised operating times at the full UPS rating.
Confirm usable energy, allowable discharge power, reserve settings, charger capacity and the expected recharge interval. A lower power load on a suitable battery configuration can have longer autonomy than a larger UPS with a smaller reserve.
Include installation and ongoing care
Check the electrical connection, distribution, bypass arrangements, ventilation and service access for the exact model. Equipment that appears suitable on capacity alone may not fit the existing installation without additional work.
Ask Powermode for a comparison using one common load and runtime brief. That makes the price, installation scope, battery configuration and maintenance requirements meaningfully comparable.
Planning guidance, not an installation specification. Final sizing, compatibility and safe work procedures require a site-specific assessment and the relevant manufacturer's instructions.
