Buying Guide: Key Considerations for Whole House Generator Systems
Choosing the right whole house generator requires evaluating several important factors to meet your home’s power needs safely and efficiently.
Power Output
Assess your home’s total power requirements by adding the wattage of essential appliances and systems you want to keep running (HVAC, refrigerator, lighting, sump pump, etc.). Generators range from 10kW to over 20kW in output—select according to your consumption demands.
Fuel Type and Efficiency
Whole house generators commonly run on natural gas, propane, gasoline, or dual fuel. Propane and natural gas offer cleaner burns and longer fuel storage, while gasoline provides easy initial availability. Dual fuel models deliver fuel flexibility, beneficial during prolonged outages.
Transfer Switch and Installation
A transfer switch automatically shifts power from the grid to the generator during outages. Ensure your system either includes or is compatible with a transfer switch rated for your home’s amperage. Professional installation is recommended for safety and code compliance.
Noise Level
Generators produce noise during operation. Models with sound-dampening features or quieter mufflers reduce disruption, making them suitable for residential areas where noise ordinances exist.
Safety Features
Look for generators equipped with carbon monoxide (CO) detectors and auto shut-off capabilities to prevent hazardous fume buildup. Remote monitoring options add convenience and safety by providing real-time generator status.
Durability and Warranty
Outdoor standby generators should have weather-resistant enclosures, often aluminum or steel. A comprehensive warranty protects your investment, especially for long-term usage scenarios.
Additional Features
Wi-Fi connectivity for remote monitoring, electric start, and self-diagnosis functions ease operation and maintenance, enhancing the user experience and reliability of your whole house power backup solution.
