Buying Guide for Diesel Whole House Generators
Power Output and Capacity
Assess your home’s total power requirements before choosing a generator. Consider appliances, HVAC systems, lighting, and critical electronics to determine the wattage needed. Generators range from 10,000 watts to 22,000 watts and beyond, with higher wattage providing coverage for larger homes and heavy usage.
Fuel Type and Efficiency
Diesel generators are prized for fuel efficiency and longevity. Some models use natural gas, propane, or dual fuel technology (gasoline & propane), offering flexibility based on fuel availability and cost. Propane is cleaner burning, while gasoline offers ease of refueling. Look for models with fuel efficiency features to reduce operating costs over time.
Installation and Transfer Switch
Automatic transfer switches (ATS) are vital for seamless power transition during outages without manual intervention. Evaluate the amperage rating (commonly 100-200 Amps) to match your home electrical system. Lower installation complexity reduces upfront costs. Some generators come with Power Line Carrier technology, simplifying wiring.
Noise Level
Consider the generator’s noise output, especially if you live in a noise-restricted area. Models utilizing sound dampening technologies or inverter designs operate quieter. Residential-friendly noise levels typically range between 60-70 dBA.
Control and Monitoring Features
Remote monitoring capabilities via Wi-Fi or mobile apps provide real-time status and maintenance alerts. Digital displays, remote starts, and self-diagnostic features enhance ease of use and maintenance management.
Safety Features
Look for carbon monoxide (CO) detection systems, low-oil shutdowns, and overload protection to ensure safe operation especially during long runtimes or enclosed spaces.
Durability and Warranty
A generator with a sturdy build, such as all-aluminum enclosures or corrosion-resistant components, will endure harsh weather conditions. Warranties ranging from 3 to 5 years provide added assurance on product longevity.
