How to choose the right UPS
A quick, vendor-neutral walkthrough of the decisions that determine which UPS is right for you.
1. Size the load correctly
Add up the connected load in watts, then convert to kVA using the equipment power factor. Leave 20–25% headroom for growth and start-up surges. Under-sizing trips the UPS on overload; grossly over-sizing wastes capital and efficiency.
2. Decide how much runtime you need
Battery backup is chosen for a target autonomy — long enough to ride through short outages, or long enough for a generator to start and stabilise. Runtime is set by the battery bank, not the UPS rating.
3. Match topology to criticality
For servers, medical, telecom and industrial control, choose Online double-conversion for zero transfer time. For low-criticality desktops, line-interactive or offline units are more economical.
4. Choose the battery chemistry
- SMF / VRLA — lowest upfront cost, familiar, 3–5 year design life.
- Lithium-ion — 2–3× longer life, half the footprint and weight, faster recharge and lower TCO.
