Sri Lanka Generator Buying Guide and Tips

• Right size: Add up your critical appliances (fridge, lights, router, small AC/pump). Many homes cope with 2–3 kW inverters, while businesses may need 5–15 kVA diesel sets.
• Noise: Inverter generators usually operate at 50–60 dB, while open-frame petrol or diesel units can exceed 70–85 dB. Consider neighbourhood noise tolerance.
• Fuel: Petrol inverters are best for portability and quiet use. Diesel sets are better for long runtimes and lower fuel costs in Sri Lanka’s market.
• Electrical safety: Always hire a licensed electrician for installation. Use an ATS kit or manual changeover switch—never backfeed the grid.
• Power quality: Choose pure sine inverter generators or AVR-equipped sets for sensitive electronics.
• Maintenance: First oil change after 5–20 hours, then follow manufacturer’s schedule. Keep filters, spark plugs, and oil in stock. Test monthly.
• Storage & weather: Sri Lanka’s tropical humidity means you need a covered, ventilated space. Use running covers for rainy days.
• Accessories: Fuel cans, wheel kits, rated cords, funnels, and small UPS units for routers and electronics.

Buying Generator in Sri Lanka FAQs

How much does generator installation usually cost in Sri Lanka?

How noisy can a generator be in Sri Lanka?
Inverter generators average 50–60 dB (conversation level). Open-frame petrol units usually run 70–85 dB, while enclosed diesel gensets are around 65–75 dB. Always check local noise restrictions in residential areas.

Which generator type and fuel are best for Sri Lanka’s climate?
For homes: petrol inverters (quiet, portable) are ideal for short outages. For frequent or long outages: diesel gensets with ATS offer efficiency and long runtimes in Sri Lanka’s hot, humid climate.

What are the typical warranties for generators in Sri Lanka?
Most portable petrol/inverter units come with 1–2 years limited warranty. Diesel standby gensets often carry 12–24 months or hour-based coverage when bought and installed via authorised dealers. Always confirm terms in writing.
