Generator Basics
What’s the difference between kW and kVA? What is the Power Factor?
- kW (Kilowatt) is the actual power your generator can deliver.
- kVA (Kilovolt-Ampere) is the apparent power produced.
- The Power Factor (PF) bridges the two:
kW = kVA × Power Factor
Most single-phase generators have a PF of 1.0, while three-phase units average around 0.8–0.9.
What is an inverter generator?
An inverter generator:
- Produces clean, stable power ideal for electronics.
- Features ECO mode for improved fuel efficiency and low noise.
- Is compact and portable — perfect for camping, outdoor events, or residential use.
What’s the difference between continuous and maximum watts?
- Continuous (Rated) Watts: Power your generator can run at safely for long durations.
- Maximum (Peak) Watts: Extra power available for a few minutes to handle start-up surges (e.g., motors, pumps).
What’s the difference between Single-Phase and Three-Phase generators?
| Feature | Single-Phase | Three-Phase |
|---|---|---|
| Voltage Range | 220–250V (or 110–120V) | 380–440V |
| Use Case | Homes, small tools | Factories, large equipment |
| Wiring | 3 wires (Live, Neutral, Earth) | 5 wires (3× Live, Neutral, Earth) |
| Power Capacity | Up to ~10kW (some 50kW) | Starts ~5kW and above |
What is a portable power station used for?
Portable power stations provide battery-powered electricity for:
- Camping & Outdoor Use
- Emergency Backup
- Campervans & Boats
- Construction Sites
- Off-grid Living
Benefits: Silent, emission-free, low maintenance, and safe for indoor use.
Choosing and Sizing Generators
What size generator do I need for my house?
- Whole-home backup: ~23kW (for 100A distribution board).
- Essential appliances only: ~5–7kW.
Example usage:- Lights: 60W
- Fridge/Freezer: 200–600W
- Kettle: 3000W
- Microwave: 1700W
Use our Power Calculator for accurate estimates.
Using and Maintaining Generators
What oil should I use?
- Petrol Generators: SAE 10W-30 (general use), SAE 5W-30 (cold climates)
- Diesel Generators: SAE 15W-40
- Always check your owner’s manual for specific recommendations.
Generator Safety and Installation
How do I safely connect a generator to my house?
- Install a changeover switch: Must be done by a qualified electrician to isolate from the mains supply.
- Ensure RCD compatibility: May require linking neutral to earth.
- Never backfeed through a wall socket: This is dangerous and illegal.
Always follow local regulations and consult a professional for installation.
