Buying Guide: What to Look For in a Generator for Small House Backup
Selecting the right generator for your small house depends on various factors:
- Power Output: Calculate your essential appliances’ total wattage. Small homes typically need between 3,000 and 10,000 running watts depending on load.
- Fuel Type: Common options are gasoline, propane, natural gas, or tri-fuel. Tri-fuel models offer flexibility during shortages or price changes.
- Runtime and Tank Size: Longer runtime means fewer refuels during an outage. Consider daily power needs and fuel availability.
- Portability vs. Standby: Portable generators can be moved and used in different locations but require manual setup. Standby generators automatically power your home and are mounted permanently.
- Noise Level: For residential areas, quieter inverters or muffled generators reduce disturbance, often rated as decibels (dB).
- Starting Method: Remote electric start adds convenience compared to manual pull-start.
- Safety Features: Look for automatic low-oil shutdown, CO sensors, and transfer switch compatibility to protect equipment and users.
- Connectivity: Multiple outlet types, including RV-ready, household, and transfer switch plugs expand usability.
- Size and Weight: Smaller, lightweight models ease transport and storage in limited spaces.
- Warranty and Support: Longer warranties and responsive customer service add long-term confidence.
By assessing these key areas, you can select the generator that best matches your small house’s power requirements, budget, and lifestyle.
