Limitation: manufacturer guidelines should be followed for optimal CO sensor maintenance.
Generac 12,500 Starting Watt Tri-Fuel
Generac’s tri-fuel portable generator provides 12,500 starting watts and 9,500 running watts with easy electric start. It offers COsense carbon monoxide detection and a 7.5-gallon fuel capacity for extended runtimes. Best for: households requiring dependable start-up and safe CO isolation. Caution: ensure compatible transfer switch and fuel supply planning for natural gas operation.
Buying Guide
What to consider when choosing a natural gas powered generator for backup power:
- Power needs: Compare peak and running watts to ensure the unit can handle essential circuits and appliances.
- Fuel flexibility: Tri-fuel options offer resilience beyond natural gas, but verify gas line requirements and storage for alternate fuels.
- Starting method: Electric start is convenient, but check battery maintenance and cold weather performance.
- Transfer switch compatibility: A transfer-switch-ready outlet simplifies integration with home electrical systems.
- Runtime and tank size: Larger tanks extend runtime on gasoline or propane; natural gas operation depends on supply pressure.
- Safety features: CO monitors and watchdog sensors help reduce risk during operation in occupied spaces.
- Portability vs. standby readiness: Heavier units offer more power but require proper handling for relocation.
Frequently Asked Questions
- What does tri-fuel mean and why is it useful? It means the generator can run on gasoline, propane, or natural gas, providing fuel options during shortages or outages.
- Is a higher peak wattage always better? Higher peak wattage helps handle startup surges, but running watts determine sustained loads. Match to your essential circuits.
- Do these generators require professional installation? For transfer switches and natural gas connections, professional installation is recommended to ensure safety and code compliance.
- How long can these run on natural gas? Runtime on natural gas depends on gas supply pressure and load; some models emphasize longer gasoline or propane runtimes.
- What safety features should I look for? Look for CO sensors, automatic shutdown on low oil or CO, and robust engine protections.
- Can I use these indoors? No. Always operate generators outdoors in a well-ventilated area to avoid CO buildup.
