8 kW to 20 kW Multiple rooms or small to medium homes (up to 2,500 sq ft) $2,500 - $6,000 Powering several large appliances or systems, small to medium-sized homes
21 kW to 50 kW Large homes, offices, commercial spaces (2,500 to 10,000 sq ft) Starting at $10,000 Extensive residential properties, larger office spaces, commercial or industrial needs

Up to 7.5 kW

These are the most accessible generators, designed for light to moderate use. They can support individual appliances such as fridges, freezers, or a handful of essential household devices. The price range for these generators is typically from $300 for the simplest, less powerful models, to $2,500 for the more advanced, near 7.5 kW units equipped with features like quiet operation and fuel efficiency. These models are especially favored for temporary solutions like outdoor events, small workshops, or emergency power for critical household appliances.

8 kW to 20 kW

Generators within this power range are more robust and can support several large appliances or systems simultaneously. This makes them suitable for powering multiple rooms, or even entire small to medium-sized homes, during an outage. The starting price for the lower end of this spectrum is around $2,500, stretching up to $6,000 for the high-end models. The mid-range generators offer a balance between the portability of smaller units and the comprehensive power capabilities of larger systems.
