South Korea Generator Buying Guide and Tips

• Right size: Small flats may only need a 1.6–2.2 kW inverter; larger homes or small businesses often require 5–10 kW; factories 10–100+ kVA diesel.
• Noise: Inverter models ~50–60 dB @ 7 m. Open-frame petrol often 70–85 dB. Diesel enclosures ~65–75 dB.
• Fuel type: Petrol inverters are portable/quiet for short outages. Diesel is best for long runtimes and efficiency. LPG/dual-fuel adds flexibility.
• Safety: Always use certified electricians for ATS/changeover installs. Never back-feed KEPCO lines.
• Electronics protection: Keep THD low for devices—choose pure sine inverter generators and good surge protection.
• Cords & outlets: Use 220 V-rated Type F cords (10–12 AWG equivalent). Keep runs short and dry.
• Maintenance: First oil change at 5–20 hours, then every 50–100 hours. Stock plugs, filters, and oil.
• Weather/storage: Korea’s humid summers and cold winters require sheltered, ventilated placement. Consider a running cover for outdoor units.
