A CLEARER BUYING DECISION
Six checks before you buy
Work through these in order and avoid choosing on VA alone.
- 01
Calculate load
Add expected watts and VA for every connected device.
- 02
Allow headroom
Leave capacity for peaks, future equipment and runtime.
- 03
Choose topology
Match protection architecture to the application.
- 04
Check waveform
Confirm output suits connected equipment.
- 05
Set runtime
Use the model’s runtime curve at your expected load.
- 06
Match the site
Check format, phase, plugs, outlets and software.

Topology describes how a UPS handles incoming power and when its inverter and battery become involved.
Standby UPS
Basic battery backup for suitable home and office electronics that primarily need outage protection.
Shop standby UPS →Line-Interactive
Automatic Voltage Regulation can correct certain input variations without using the battery.
Shop line-interactive →Online Double Conversion
Continuously regenerates output and offers strong isolation from input disturbances.

UPS BUYING QUESTIONS
Answers before you choose
Clear guidance on capacity, runtime, topology, batteries and installation.
Browse all UPS →What is a UPS and what does it do?+
A UPS provides short-term battery power when mains power fails. Depending on its design, it can also provide surge protection, voltage regulation and power conditioning.
How is a UPS different from a surge protector?+
A surge protector helps reduce the effect of voltage spikes but does not normally keep equipment running in a blackout. A UPS adds battery backup for brief operation or safe shutdown.
How do I choose the right UPS size?+
Add the expected wattage of every connected device, then choose a UPS whose watt and VA limits both exceed that load. Allow headroom for peaks, future devices and useful runtime.
What is the difference between VA and watts?+
Watts measure real power used by equipment, while VA measures apparent power. The connected load must remain within both ratings.
How much spare capacity should I allow?+
Avoid planning to run at the maximum rating. Around 20% or more headroom is a useful starting point, but use the exact model’s sizing and runtime information.
How long will a UPS run during an outage?+
Runtime depends on the battery system and connected load. Higher loads normally reduce runtime, so check the manufacturer’s runtime curve at your expected watt load.
What are standby, line-interactive and online UPS systems?+
Standby provides basic backup, line-interactive adds voltage regulation, and online double-conversion continuously regenerates output for more sensitive or critical equipment.
What is AVR?+
Automatic Voltage Regulation can boost or reduce incoming voltage on supported line-interactive systems without using battery power.
Do I need pure sine wave output?+
Pure sine wave is often preferred for sensitive electronics and active-PFC power supplies. Check the requirements of the equipment you intend to connect.
Should I choose desktop, tower or rackmount?+
Choose the format that fits the installation. Capacity and runtime still need to be sized separately.
What is single-phase versus three-phase?+
Single-phase is common in homes, offices and small server environments. Three-phase supports larger loads. Match the UPS to the site supply and protected equipment.
What is VRLA versus lithium-ion?+
VRLA is sealed lead-acid technology widely used in UPS systems. Lithium-ion designs may offer lower weight, faster charging and longer service life in supported products.
Can I replace the battery?+
Many models support replacement batteries, but the battery or cartridge must be specified as compatible with the exact UPS.
How often should a battery be replaced?+
Service life varies with chemistry, temperature, loading and discharge frequency. Use battery-health indicators, testing and manufacturer guidance.
Can I connect any extended battery module?+
No. Extended battery modules are model-specific because voltage, connectors, charging capability and firmware support can differ.
