The cost of the generator is a very important component in the buying process of a generator. The cost depends on various factors such as the brand, performance and build quality, type of generator, and advanced features such as remote start, CO sensor, and economy mode.
In this article, we have done our best to estimate the cost of a 75000-watt generator in terms of both upfront and running costs. For our analysis, we chose the best 7500-watt generator available in the market.
The upfront cost of a 7500-watt generator, which includes the generator, transfer switch, inlet box, cord, and labor installation, will cost you around $3485 for a single fuel, $3569 for dual fuel, $3844 for an inverter generator, and $4619 for a standby generator. The running cost will be $6.7 per day and $203 per month if you run it daily for three hours at half load.
