Buying Guide for Whole House Backup Generators
When selecting a whole house backup generator, consider the following key factors to ensure you choose the right unit for your needs:
Power Output
Determine your home’s power requirements by calculating essential appliances and systems to run during an outage. Generators range from 7,000 watts to over 28,000 watts; a higher wattage supports large homes and multiple devices simultaneously. Make sure the generator can comfortably handle peak and running wattage demands.
Fuel Type and Availability
Common fuel sources include gasoline, propane, natural gas, and battery power. Tri-fuel generators offer versatility, allowing the use of multiple fuels depending on supply and emergency conditions. Consider local fuel accessibility and storage when picking a fuel type.
Transfer Switch and Integration
A transfer switch is essential to safely transfer power to your home’s electrical circuits without back feeding the grid. Ready transfer switches or included ones simplify installation and operation. Ensure compatibility with your home’s electrical panel.
Portability and Installation
Portable generators offer flexibility but may require manual setup and refueling. Standby generators typically install permanently outside your home and start automatically when power fails. Battery-based options like the EF ECOFLOW are quieter and require no fuel but have capacity limits and longer recharge times.
Safety Features
Look for carbon monoxide (CO) shutoff systems and alerts to prevent dangerous fume buildup. Automatic low oil shutdown protects the engine from damage. Rubber-covered outlets enhance electrical safety. Some units include remote monitoring or app-control for added oversight.
Runtime and Fuel Capacity
Consider the size of the fuel tank and how many hours the generator can run at half or full load. Longer runtime reduces the need for frequent refueling during extended outages. Built-in fuel gauges aid in fuel level monitoring.
Noise Level
Generators produce noise which may be disruptive in residential areas. Battery-powered generators tend to be quieter, whereas large gasoline units can be louder. Check the decibel levels and consider placement to minimize noise impact.
