Uninterruptible Power Supply (UPS) Vs. Backup Generators
Difference Between Uninterruptible Power Supply (UPS) and Backup Generators
They both sound like the answer to your power outage problems – but they are actually two very different systems that can either work independently or in-line with each other. We discuss the differences between the two in detail and the merits and disadvantages of each.
Uninterruptible Power Supply
A UPS is a system that will step in instantly when there is a power outage, ensuring nothing turns off or stops as soon as there is a loss of power. As you can imagine, hospitals, data centres and emergency services all have these in place.
A UPS isn’t a long-term fix to the power outage – generally, they run from a few minutes to an hour post outage (depending on type). This gives you time to get your generator or backup power supply running.
- Power consistency
- Power continuity
- Prevents loss of data
- Protects machines/equipment
- Reduced noise when running
- Generally smaller than a backup generator
- Requires high-quality batteries
- The performance is affected by the environment it’s placed in
- Requires expert installation
- Uses power when not in use
We recently wrote a blog that covers the advantages and disadvantages of a UPS in more detail.
Backup generators are sat waiting for the blackout to happen and have to be booted up once everything is off. They don’t jump in and keep things running seamlessly like a UPS does, but backup generators do provide a longer lasting solution whilst the power supply is off.
- Continual flow of power
- Dependable electrical power when needed
- Ensures a longer duration of power after an outage
- Protects you against electrical surges
- Come in a range of sizes dependant on your business needs
- Noisy – they need to be housed in their own room
- Requires an expert to install
- Can be a costly form of power
- Doesn’t kick in seamlessly when power outages happen (10-20 second delay) – this can lead to data loss and machine damage
- Requires a fuel supply which can be an added expense
- Can be dangerous if gas or diesel supply is compromised
- Requires regular maintenance and servicing
Using Both a UPS and a Backup Generator
In an ideal world, you would want to invest in both a UPS and a backup generator as they are built to work together during a power outage. They both have a wide range of benefits and disadvantages, so the main question you need to ask is: “Can my business afford to lose any power during an outage, even if it’s just 30 seconds?”
If the answer to this is yes, then you may wish to use just a backup generator and manage without power until a trained individual is able to start the backup generator. We’ve written an article on the effect power outages can have on your business.
If the answer is no, then it’s essential for your business to invest in a UPS!
