Generators for Emergency Backup
For emergency backup, a standby diesel generator with an auto-transfer switch (ATS) starts automatically within 10-30 seconds of a power outage. Homes need 6-22kVA, businesses 22-100kVA, and critical facilities 100kVA+. Hanson Hire supplies, installs and services standby generators, plus 24/7 emergency hire.
Emergency backup power keeps businesses running when the grid fails. Hanson Hire supplies and installs standby diesel generators with auto-transfer switches for automatic startup, plus 24/7 emergency hire for unexpected outages.
Generators for Emergency Backup
When the grid fails, businesses and critical facilities need automatic backup power to avoid costly downtime, data loss and safety risks. Standby generators with auto-transfer switches (ATS) start automatically within seconds of a power outage.
What Emergency Backup Needs
- —Standby diesel generators with ATS for automatic startup
- —Single-phase (6-22kVA) for homes and small businesses
- —Three-phase (22-500kVA) for commercial and industrial facilities
- —Heavy industrial (500kVA+) for data centres, hospitals and large infrastructure
- —Diesel refueling for extended outages
How Standby Generators Work
A standby generator is permanently installed and wired into your switchboard via an auto-transfer switch (ATS). When mains power drops, the ATS signals the generator to start, then transfers the load — typically within 10-30 seconds. When mains power returns, the ATS transfers back and the generator cools down and shuts off.
Sizing for Emergency Backup
For essential home circuits (fridge, lights, some power points), a 6-11kVA standby unit is typical. For whole-home or small business backup, 11-22kVA. For commercial facilities, 22-100kVA. For data centres, hospitals and large industrial sites, 100kVA to 1000kVA+. Use our size calculator or get a quote for a tailored recommendation.
