Dominica Generator Buying Guide and Tips

• Sizing: Add up your essentials—fridge, lights, router, fans, small pump. A 2–3 kW inverter handles small homes; larger homes or businesses may need 5–10+ kW.
• Noise: Inverters run 50–60 dB, while open-frame petrol/diesel can exceed 70–85 dB. Mind neighbours in urban Roseau.
• Fuel choice: Petrol inverters are portable for short outages. Diesel sets excel for long hurricane-related outages.
• Electrical safety: Always use a licensed electrician. Install a compliant changeover or ATS—never back-feed the grid.
• Power quality: Sensitive electronics require pure-sine inverter generators or AVR-equipped diesel sets.
• Cords & outlets: Use 230 V-rated cords (10–12 AWG). Protect from rain with outdoor covers.
• Maintenance: Do first oil change early, then follow service intervals. Keep filters, plugs, and spare oil handy. Test monthly.
• Weather & storage: Tropical humidity requires covered, ventilated placement. Consider a running cover.
• Accessories: Wheel kits, fuel cans, funnels, heavy-duty cords, and UPS units for routers.
