Buying Guide
What to consider when choosing a house-backup generator:
- Power needs: List essential circuits and total watts to determine required running watts. Larger homes or multi-apartment spaces benefit from models in the 9,500–13,500 running watts range.
- Fuel type and availability: Dual-fuel and tri-fuel units offer flexibility during outages. Consider fuel storage, fuel cost, and emissions when choosing gasoline, propane, or natural gas options.
- Transfer switch readiness: If you want seamless power to your home circuits, choose models with transfer-switch compatibility or ready-to-wire configurations.
- Run time and tank size: Larger tanks deliver longer runtime. Match tank capacity with typical outage durations for your area.
- Outlets and safety: Check outlet types (GFCI, RV, 30A/50A) and safety features like rubber outlet covers and CO shutdown sensors.
- Portability vs. permanence: Portables are easier to move, but heavier units may require a dedicated storage area and a stable setup for outdoor use.
Frequently Asked Questions
- What is the difference between peak watts and running watts? Answer: Peak watts indicate maximum surge power, while running watts reflect continuous output. Choose a unit with running watts that cover your essential loads with some margin for surge.
- Which fuel is best for home backup? Answer: Dual-fuel or tri-fuel units offer flexibility; natural gas can provide continuous supply if connected to a gas line, while propane allows easy storage. Gasoline typically offers higher peak watts.
- Do I need a transfer switch? Answer: A transfer switch enables seamless handoff of power from the grid to the generator for selected circuits, improving safety and convenience during outages.
- How long do these generators run on a full tank? Answer: Run-time varies by fuel type, load, and tank size. Look for models with larger fuel tanks and efficient engines to achieve longer runtimes.
- Are there safety concerns with using a generator indoors? Answer: Do not operate generators indoors or in enclosed spaces. Use outdoors on a dry, level surface with proper ventilation to avoid carbon monoxide risk.
- What maintenance is required? Answer: Regular oil checks, spark plug inspections, and air filter maintenance are typical. Digital hour meters help schedule servicing and oil changes.
