Sao Tome and Principe Generator Buying Guide and Tips

• Right size: Calculate essential loads (fridge, lights, water pump). Small homes often need 2–3 kW inverters; businesses may require 5–20 kVA diesel sets.
• Noise matters: Inverters are 50–60 dB at 7 m; open-frame petrol >70 dB. Consider neighbors and noise restrictions.
• Fuel choice: Petrol inverters are lightweight and portable. Diesel sets are more fuel-efficient and suited for long outages in the tropics.
• Electrical safety: Hire a licensed technician to install ATS or changeover switches—never back-feed power lines.
• Humidity and storage: Store under cover with ventilation; humid weather requires more frequent filter changes. Consider a running cover.
• Maintenance: First oil change at 5–20 hours, then every 50–100 hours. Stock filters, plugs, and spare oil.
• Accessories: Wheel kits, fuel cans, funnels, rated generator cords, and UPS backups for routers.
