Quick Answer
The cost of whole-house generators is influenced by factors such as capacity, fuel type, and advanced features like automatic transfer switches and remote monitoring. Larger generators with higher capacities and advanced features tend to be more expensive. Additionally, the cost of installation and maintenance also plays a significant role.
Generator Capacity and Fuel Type
Whole-house generator capacity is a critical factor in determining cost. A 20-kilowatt generator, for example, may cost between $3,000 to $6,000, while a 50-kilowatt generator can range from $8,000 to $15,000. Fuel type is also a significant factor, with propane and natural gas generators generally being more expensive than diesel or gasoline generators. For instance, a 20-kilowatt propane generator can cost around $5,000 to $10,000, while a diesel generator of the same capacity may be priced between $3,000 to $6,000.
Advanced Features and Installation
Advanced features like automatic transfer switches, remote monitoring, and load management systems can significantly impact the cost of a whole-house generator. An automatic transfer switch can add $1,000 to $2,000 to the overall cost, while a remote monitoring system may add an additional $500 to $1,000. Installation costs can also vary greatly depending on the complexity of the job and local labor costs. On average, installation costs can range from $1,000 to $3,000, although some projects may require more extensive work, increasing the overall cost to $5,000 or more.
