Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.
