Buying Guide: Key Considerations For Emergency Home Generators
What size do you need? Estimate total running watts of the appliances you intend to power during an outage. Choose a generator with a bit more capacity than your total to handle startup surges.
Gas vs propane vs dual fuel: Gasoline is common and convenient, propane stores longer but may have limited availability in shortages. Dual-fuel units offer flexibility for longer outages.
Quieter operation and safety features: Inverter generators tend to run quieter and deliver cleaner power. Look for CO alarms, automatic shutdown, and proper ventilation.
Portability vs standby capability: Portable open-frame units are affordable and flexible. If you want seamless automatic power during outages, explore transfer switches and standby systems (often integrated with whole-house panels).
Safety and compliance: Ensure EPA, state, and local requirements are met. Consider models with low oil shutdown and overload protection for safer operation.
Frequently Asked Questions
- What size generator do I need for a typical home outage?
Common homes may require 4000-7000 running watts for essential circuits. For whole-home backup, consider 10000 watts or more, depending on your appliances and climate control needs.
- Is dual-fuel better than single-fuel?
Dual-fuel offers flexibility and longer run times in emergencies, especially when gas supply is uncertain. It can be heavier and more complex to operate.
- Do inverter generators provide enough power for home backup?
Inverter generators are efficient and quiet, suitable for powering essential circuits and smaller loads. For full-house power, larger models or parallel setups may be necessary.
- What safety features should I look for?
Look for CO alarms, automatic shutdown on low oil, overload protection, proper ventilation, and transfer switch compatibility to safely connect to home circuits.
- How important is a transfer switch?
A transfer switch simplifies connecting a generator to home circuits. It protects the grid and reduces the risk of backfeeding when outages occur.
- Can I run a generator indoors or in a garage?
Generators should always operate outdoors in a well-ventilated area to prevent carbon monoxide buildup. Never operate in enclosed spaces.
