What Size Generator Do I Need?

The generator size you need depends on total running load, startup power requirements, and how equipment is used. Correct sizing improves reliability, efficiency, and reduces the risk of breakdowns. A professional assessment ensures the generator meets operational demands safely.

Common Generator Sizing Mistakes

  • Ignoring startup loads

  • Running generators at full capacity continuously

  • Not accounting for future expansion

Long-Term Performance Depends on Maintenance

Correct sizing alone is not enough. Ongoing servicing ensures:

  • Rated output is maintained

  • Electrical systems remain stable

  • Fuel consumption stays efficient

How do I know what size generator I need?

Generator size is determined by adding total running load and startup load of all equipment that will operate simultaneously.

Yes. Oversized generators can operate inefficiently, leading to increased fuel consumption and mechanical issues if not properly loaded.

If you’re located in Brisbane, the Gold Coast, Toowoomba, or the Northern Rivers and require reliable generator servicing or repairs, Equipment Services and Machinery provides professional inspection, maintenance, and ongoing support. Phone 07 3607 3311 for enquiries.
