Buying Guide
Key considerations when selecting a 12,500-watt generator include fuel flexibility, startup method, and run-time expectations. Compare peak watts to your essential loads to avoid underpowered outages. Look for transfer switch readiness, safety features like CO sensors, and durable construction for long-term use.
- Fuel flexibility: Dual-fuel or tri-fuel options offer backup options beyond gasoline when supply is disrupted.
- Starting method: Remote electric start provides quick power with minimal effort; recoil or manual starts are more basic.
- Run-time and fuel tank size: Larger tanks extend operation during outages; check runtime at half or full load to estimate needs.
- Safety features: CO sensors, automatic shutdown, and grounded outlets help prevent hazardous conditions.
- Outlets and transfer readiness: Ensure the model has the needed 120V/240V outlets and that a compatible transfer switch is available.
Frequently Asked Questions
- What does “12,500 starting watts” mean versus running watts?
– Starting watts are the surge power a generator can supply to start devices; running watts are the steady-state power during operation. - Do I need a transfer switch?
– A transfer switch allows safe connection of a generator to home circuits; it is highly recommended for whole-home backup. - Is dual-fuel better than single-fuel?
– Dual-fuel offers flexibility if one fuel type becomes scarce; it may come with added weight and cost. - How important is CO safety?
– CO safety auto-shutoff protects against dangerous carbon monoxide exposure in enclosed spaces. - Can I run these indoors?
– Generators should always be used outdoors with proper ventilation to avoid hazardous fumes and heat buildup.
