"In May of 2023 I had a system installed. When hurricane Milton ? came through the system failed. Called for emergency repair. Was told for an upfront payment, a technician would arrive within 48 hours. Technician did not come. After repeated calls. I was told because of an over abundance of calls I was pushed back a week. Duke Energy restored power to our home before Genrex came by. Mind you the Generx is supposed to perform during emergency. Now to get a service for a annual check up, to maintain warranty. Was told my last service person used superior parts. Why would they not supply quality products initially? I am very unhappy with Generx. I will not recommend Generx. In fact I will strongly advocate against this company to family and friends. "

Generator Install questions, answered by experts

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

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.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

No, you cannot plug a generator directly into a wall outlet in your home. Plugging in a generator without an interlocking kit, extension cord, or wall outlet receptacle is incredibly dangerous and can cause back-feeding—power from the generator back-feeds into utility lines. Also, if the main power comes back on while your generator is on, it could damage the generator and cause a house fire.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.
