1How do I know what size generator I need for my home?
Add up the wattage of essential appliances you want to run simultaneously—typically your AC unit (3000-5000W), refrigerator (600W), lights (500W), and water pump (1500W). Buy a generator rated 20-30% higher than this total to handle startup surges and ensure it runs efficiently.
2What's the difference between inverter and conventional generators?
Inverter generators produce stable, clean power safe for sensitive electronics like laptops and phones, while conventional generators are cheaper but can damage electronics. Choose inverter if you need to run computers or modern appliances; conventional works fine for power tools and basic lighting.
3Should I choose a petrol or diesel generator?
Diesel generators are more fuel-efficient and better for heavy, continuous use, while petrol generators are lighter, quieter, and cheaper upfront. For household backup during occasional outages, petrol is practical; for construction sites or long-term use, diesel saves money.
4What maintenance should I expect with an emergency generator?
Plan for regular oil changes (every 50-100 hours), fuel stabiliser if storing long-term, and monthly test runs to keep it working. Proper maintenance prevents starting issues and extends the generator's lifespan significantly.
5Is it worth paying more for a portable generator with wheels and handles?
Yes, if you need to move it between locations or store it in tight spaces—wheels save effort and prevent back strain. For permanently installed backup power, a stationary model offers better stability and is usually more durable.
