Buying Guide
What type of backup power do you need? Consider whether you want a standby system that automatically starts during an outage or a portable unit you power manually. Standby generators typically offer seamless whole-house protection, while portable models excel in flexibility and short-term usage.
Key considerations
- Power needs: List essential appliances (refrigerator, heating/cooling, lights, medical devices) and estimate total wattage. Choose a model with a comfortable wattage headroom above your peak needs.
- Fuel type: Natural gas or liquid propane offer reliability in area outages. Dual-fuel options provide flexibility when one fuel source is unavailable.
- Transfer switch compatibility: For whole-house backup, a transfer switch ensures safe, automatic switching without manual unplugging.
- Mobility vs. permanence: Standby units stay outdoors and auto-start; portable units move where needed but require manual operation.
- Remote monitoring: WiFi or cellular connectivity helps track status and maintenance; assess app reliability and any subscription requirements.
- Installation and maintenance: Standalone standby systems often require professional installation and service plans; portable units need routine maintenance and fuel management.
Planning tips
- Match generator output to your critical circuits first, then expand as budget allows.
- Consider noise levels and neighborhood restrictions when selecting a portable model.
- Store fuel safely and follow local regulations for fuel storage and generator placement.
FAQ
- What is the difference between standby and portable generators?
- Should I choose dual-fuel or single-fuel?
- Do I need a transfer switch?
- How do I determine how much wattage I need?
- Is remote monitoring important?
- How long do generators typically run on tank fuel?
Standby generators are permanently installed and configured to start automatically during an outage. Portable generators are moveable units that require manual operation and setup.
Dual-fuel provides flexibility when one fuel source is scarce, making it a resilient choice for longer outages.
For automatic whole-house backup, a transfer switch is essential for safe switching and to protect the generator and home wiring.
Add up the running watts of essential devices and apply a safety margin. Include air conditioning, refrigerator, furnace, and lighting as core considerations.
Remote monitoring helps track performance and maintenance without on-site checks, which is useful for off-site homeowners or long outages.
Run time varies by model and load. Portable units with larger tanks can run for many hours at partial load; standby systems vary by fuel source and use.
