A whole house diesel generator is a backup power system that is permanently installed outside your home. It is connected to your home’s electrical system and powered by a diesel engine. When the main power supply fails, the generator automatically starts and provides electricity to your entire home. These generators are designed to handle high power loads and can run for extended periods, making them ideal for homes in areas prone to frequent power outages or extreme weather conditions.
Why Choose a Whole House Diesel Generator?
Whole house diesel generators offer several advantages for homeowners:
Automatic Operation: They start automatically during a power outage, ensuring uninterrupted power supply.
High Power Output: Whole house generators can power an entire home, including essential appliances like refrigerators, air conditioners, and heating systems.
Fuel Efficiency: Diesel engines are more fuel-efficient than gasoline engines, reducing operating costs.
Durability: Diesel generators are built to last and can withstand heavy use.
Low Maintenance: With fewer moving parts, diesel generators require less frequent maintenance.
Key Features to Look for in a Whole House Diesel Generator
When selecting the best whole house diesel generator for your home, consider the following features:
Power Output: Ensure the generator can handle the total wattage of your home’s essential appliances.
Fuel Tank Capacity: A larger fuel tank means longer runtimes without refueling.
Noise Level: Look for generators with low noise emissions, especially if you live in a quiet neighborhood.
Automatic Transfer Switch (ATS): This feature allows the generator to start automatically during a power outage and switch back to the main power supply when it is restored.
Safety Features: Overload protection, low-oil shutdown, and circuit breakers are essential for safe operation.
