GENERATOR SIZING
A disciplined preliminary sizing route—not a substitute for final engineering verification.
Use connected load, starting behavior, duty and reserve to frame the likely generator class before final model selection.
SIZING LOGIC
Four inputs determine whether a simple load sum is misleading.
1
Running loadTotal expected simultaneous kW/kVA under the operating scenario.
2
Motor / compressor startingLargest starting event can dominate transient performance.
3
Load sequencingStaged starts can materially reduce the required transient capacity.
4
Reserve & dutyPrime/standby operation and growth margin affect final selection.
| Input | What to provide |
|---|---|
| Largest loads | Motor, AC, pump, compressor or other starting load |
| Total operating load | Expected simultaneous kW or kVA |
| Duty | Prime, standby or continuous project requirement |
| Automation | Manual start, ATS/AMF or synchronization |
| Site | Indoor/outdoor, temperature and acoustic constraints |
