Buying Guide
What should I look for in a 15000-watt generator?
Key factors include fuel type and availability, run time at typical loads, starting method (electric vs recoil), transfer-switch readiness, and safety features like CO sensors. A dual-fuel design adds versatility during fuel shortages. Consider your home’s total load to ensure the generator can handle essential circuits.
Gas vs. propane: which is better for long outages?
Gas will typically provide higher peak power, while propane burns cleaner and stores longer. For long outages, propane can be advantageous due to shelf life and availability. Some models offer tri-fuel options for even more flexibility.
How important is run time and fuel capacity?
Longer runtimes reduce refueling needs during emergencies. Look for large tank capacities (6–10+ gallons or more) and high efficiency. Run time varies with load; plan for the essential circuits you want to keep powered.
What about noise and placement?
Noise levels vary by model; many generators operate around 70–78 dBA at a distance. Place the unit away from living spaces, or use a sound-reducing enclosure and proper ventilation. Always follow local noise and clearance regulations.
Are automatic start and transfer switches necessary?
Automatic start with a transfer switch makes power transfer seamless during outages, reducing manual steps. If you rely on a home generator for critical loads, ensure the model supports ATS compatibility and NEMA outlets suitable for your transfer switch.
Safety and maintenance considerations
CO detection and automatic shutoff features mitigate fumes risk. Regular maintenance, oil checks, and air filter cleaning extend life. Always use fresh fuel and store it safely, away from living spaces.

FAQs
- What is the difference between peak watts and running watts?
- Is a dual-fuel generator better for home backup?
- Do I need a transfer switch for home backup?
- How loud are these generators?
- What maintenance is required for these generators?
Peak watts are the maximum surge power the generator can deliver briefly, while running watts represent continuous power during normal operation. For essential loads, rely on running watts.
Dual-fuel offers flexibility if one fuel source becomes scarce. It also enables longer operation with propane, which stores longer without degradation.
For safe power transfer to home circuits, a transfer switch is recommended. It prevents backfeeding and coordinates with your electrical panel to power selected circuits.
Most units operate around 70–78 dBA at a distance. For noise-sensitive areas, consider placement, enclosure, or selecting models marketed as quieter operation.
Regular oil changes, air filter checks, spark plug inspections, and fuel stabilization are standard. Follow the manufacturer’s maintenance schedule for optimal performance.
