Buying Guide for Whole House Inverter Generators
Power Output and Load Capacity
When selecting a whole house inverter generator, understand your power requirements by calculating the total wattage of essential appliances and systems you want to run simultaneously. Generators range from 5000 watts up to 22,000 watts or more, so choose one that covers your peak load plus a margin for startup surges, especially for HVAC units and refrigerators.
Fuel Type and Efficiency
Dual fuel models provide flexibility to run on gasoline or propane, useful in emergencies when one fuel type may be scarce. Portable units with eco-modes reduce fuel consumption. Standby generators often run on natural gas or propane connected directly to home supply, offering continuous power without manual refueling.
Portability vs. Standby Installation
Decide if you need a portable generator you can move for outdoor use or an automatic standby unit permanently installed outside your home. Portable inverter generators offer quiet operation and clean power but typically serve smaller loads compared to standby systems designed for whole house integration.
Start Mechanisms and Controls
Remote electric start and wireless key fobs enhance convenience, letting you start the generator from a distance. Automatic transfer switches enable seamless power transition during an outage, especially for standby models. Digital displays and WiFi monitoring add helpful real-time data about fuel and generator performance.
Safety Features
Look for generators with low THD (<3%) for protecting sensitive electronics. Carbon monoxide sensors that automatically shut down the generator when dangerous fumes build up are essential for indoor use or enclosed spaces. Transfer switch readiness ensures safer connection to home electrical circuits.
Noise Levels
Inverter generators are known for quieter operation compared to traditional models, with noise levels typically between 60 and 70 decibels. Consider noise if you live in noise-restricted areas, use your generator for camping, or prefer minimal disturbance during outages.
Warranty and Durability
A strong warranty and durable build materials provide peace of mind and protect your investment. Look for units backed by multiple years of warranty and featuring weather-resistant enclosures if the generator will sit outdoors.
