Generators & UPS Systems
Depending on your power needs, your backup setup may involve a generator, a UPS, or both. Generators provide long‑duration backup during extended outages, while UPS systems deliver instant, clean power when the mains supply drops, making them essential in power‑critical sectors such as hospitals and data centres where even a split‑second interruption can cause damage or safety risks.
A UPS protects sensitive equipment from dips, spikes and short interruptions, while the generator sustains your operation for the full duration of an outage. Used together, they create a resilient power strategy: the UPS absorbs the immediate impact, preventing downtime or data loss, and the generator seamlessly takes over for long‑term support.
The right setup ultimately depends on how much interruption your organisation can tolerate. If a brief power dip is acceptable, a generator alone may be sufficient. But if uninterrupted power is essential, even for a few seconds, a UPS‑and‑generator combination ensures your operations stay online regardless of grid instability or unexpected outages.
Generators vs UPS – What’s the Difference?
UPS (Uninterruptible Power Supply)
A UPS provides instant, no‑break power the moment mains supply fails.
It protects your equipment by:
- Delivering immediate backup with zero interruption
- Filtering spikes, surges and transients
- Maintaining power until the generator starts
Generators
Generators provide long‑duration backup power for extended outages.
They:
- Support full site loads for hours or days
- Automatically start when signalled by your UPS/ATS
- Keep your facility operating throughout prolonged failures
Do You Need Both?
Whether you need both a generator and a UPS in your power resilience setup depends on your power demands.
- UPS = first seconds of protection
- Generator = sustained power
