"The crew very polite and informative. The whole house generator installed in one day and my place was left clean. The installation project was done in a cosmetic pleasing manner and no ugly pipes or wires are visible. I was given a detailed cost of the project and kept informed at all times. It was not the lowest bid but the work was excellent and I am very happy with the finished project. The office staff are very helpful and their excellent service and detailed bid is why I chose to go with LT Generator."

"Sergio and his assistant installed an EV charger at my place, and they did an amazing job. I’m so glad I hired them. Their price was reasonable compared to other contractors. I highly recommend them and would definitely use their company again for any future jobs."

"The electricians installed two outlets and one LED light fixture in a very professional manner. They provided good advice and suggested that I consider rejunvenating my electrical panel as my home is now 26 years old without pressuring me to have it done immediately. I will definitely consider Trout Electric when I decide to have it done."

Generator Install questions, answered by experts

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. 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.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.
