GENERATOR SELECTION MADE EASY
- List down the wattages of all the appliances you need to run together. If an appliance is rated in Amps only, multiply AMPS x VOLTS = WATTS
- Add up the total of WATTS of all these appliances.
See example below: - From the Gentech brochure select a generator that can deliver both the running and starting watts with ease.
| UNIT | RUNNING WATTS | STARTING WATTS |
|---|---|---|
| Fridge | 300 | 750 |
| TV | 120 | 120 |
| Lights | 75 | 75 |
| Freezer | 200 | 500 |
| 1 hp Pump | 750 | 4500 |
| TOTAL | 1445 | 5945 |
IMPORTANT: All Gentech portable petrol sets can provide twice their normal output for a short period. Therefore in the above example, a 4.4kVA Gentech generator can deliver 3500 watts running and 7000 watts starting.

kW/kVA @ 8pf kVA x 0.8 = kW 2000 Watts = 2.5kVANote: Electric motors need 3x motor hp to start than to run, add this to your required kW.
