Buying Guide: Key Purchase Considerations
- Power needs: Assess your essential appliances and their wattage. Look for units with peak wattage that exceeds your surge requirements to avoid tripping breakers.
- Fuel flexibility: Dual-fuel generators offer gasoline and propane options. propane typically stores longer and is cleaner burning, but gasoline can provide higher peak power.
- Transfer switch readiness: For home backup, a transfer switch compatible generator streamlines connection to your main panel and improves safety during outages.
- Safety features: CO sensors, low-oil shutdown, and remote start help protect your family and equipment during operation.
- Noise and emissions: Inverter-based models tend to run quieter and with cleaner emissions, but look at THD ratings if you plan to power sensitive electronics.
- Outlets and compatibility: Ensure the generator has outlets that fit your appliances, RV hookups, and workshop tools; consider RV-ready or Twist-lock outlets for heavy loads.
- Runtime and tank size: Larger tanks and efficient engines extend runtime between refuels, especially during extended outages or remote job sites.
- Portability vs. capacity: Heavier units may require wheeled carts or dedicated storage; balance portability with continuous power needs.
FAQ
- What does “peak watts” mean? Peak watts indicate the maximum power a generator can deliver for a brief surge, such as starting appliances.
- Is dual-fuel better than single-fuel? Dual-fuel offers flexibility and may extend runtime, but it can be more complex and heavier than single-fuel models.
- Do I need a transfer switch? For home backup, a transfer switch is highly recommended to safely connect a generator to your electrical system.
- What is CARB compliance? CARB approval means the generator meets California air quality standards and is considered permissible in many regions.
- Can I power my whole house with a 12000W generator? It depends on your home’s total running watts and peak demands. A transfer-switch with properly sized circuits is essential for safe, full-home backup.
- What is THD and why does it matter? Total Harmonic Distortion indicates how clean the electrical output is. Lower THD is better for powering electronics and sensitive devices.
