Buying Guide
What size do you actually need?
Estimate your essential circuits and total load to determine running watts. Prioritize models with a buffer above your calculated needs to avoid overloading during peak demand.
Fuel type and availability
Dual- or tri-fuel options add flexibility when a single fuel source is scarce. Consider your maintenance routine and local fuel costs when selecting.
Portability vs. power
Open-frame designs offer higher output at the cost of portability and noise. Inverter models prioritize clean power and quiet operation but may cap maximum wattage.
Safety and startup features
CO sensors, automatic low-oil shutdown, and remote starts improve safety and convenience. Ensure your setup includes proper transfer switches and weather protection for outdoor use.
Maintenance and run time
Check fuel tank capacity and expected runtime at typical loads. Look for hour meters and user-accessible oil and air filter maintenance points to simplify upkeep.
Which one should you buy?
- For maximum flexibility and multi-fuel options: Generac Tri-Fuel and Westinghouse Dual Fuel 12,500/13,000+ watts.

Frequently Asked Questions
- What does “dual fuel” mean in home backup generators?
It means the generator can run on more than one type of fuel, typically gasoline and propane, increasing fuel choice during outages.
- Are inverter generators suitable for whole-house backup?
Inverter generators are ideal for sensitive electronics and quieter operation, but may not meet very high wattage needs for large homes.
- Do I need a transfer switch for a home backup generator?
Yes, a transfer switch safely routes power to essential circuits and prevents back-feeding into the grid.
- What maintenance is typically required?
Regular oil changes, air filter checks, spark plug replacement, and fuel stabilization as needed are common maintenance tasks.
- How long can these generators run continuously?
Runtime depends on tank size and load; consult each model’s specifications for approximate hours at a given load.
