United States of America Generator Buying Guide and Tips
- Right size: Add up wattage of essentials (fridge, lights, sump pump, router). Portables handle 2–8 kW; whole-house standby units often 10–24 kW+.
- Noise levels: Inverters ~50–60 dB, open-frame portables ~70–85 dB, standby units ~65–75 dB. Check local ordinances for neighborhood noise restrictions.
- Fuel choice: Gasoline is common; propane and dual-fuel extend runtime and storage life. Diesel suits heavy-duty or commercial needs.
- Safety first: Never backfeed. Use transfer switches or interlock kits. Install a CO detector nearby.
- Accessories: Wheel kits, rated generator cords, covers, and surge protectors make ownership easier.
- Maintenance: First oil change after 5–20 hours, then every 50–100 hours or annually. Keep oil, filters, and spark plugs handy.
- Weather & storage: Place units on a stable, ventilated, weather-protected surface. Use running covers for safe operation outdoors.
