"Switching from a gas car to an EV entails a sharp learning curve. Having a charger installed with an outlet that didn’t previously exist isn’t an easy job. Josiah installed a new outlet, changed the paneling, and set up my charger in two hours. It’s hard enough just to get an electrician to show up.

The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000
Partial-Home Generators (9kW–20kW): $2,000 to $6,500
Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators.
