A generator keeps lights and fans on — or becomes a noisy money pit if you undersize/oversize wrong.
Size From Your Loads
Add watts of devices you’ll run together (lights, fans, fridge surge, router, TV). Fridges and pumps need startup headroom.
If you only need the router + lights briefly, compare with a UPS/inverter first.
Petrol vs Diesel vs Inverter Generators
| Type | Notes |
|---|---|
| Petrol | Common, lighter; fuel cost/noise vary |
| Diesel | Often better for longer heavy use; heavier |
| Inverter generator | Cleaner power for electronics; pricier |
Safety Non-Negotiables
- Never run indoors — carbon monoxide kills
- Proper outdoor placement and dry footing
- Changeover/transfer done by a qualified electrician — don’t backfeed the grid
- Fresh fuel storage away from kids/heat
Buyer Checklist
- Spare parts availability in your city
- Warranty + service centre
