"Tui and his sons provided outstanding service to us, helping resolve an electrical problem we had experienced for years. Our home had too many appliances running on one circuit, which caused the breakers to trip, especially when using the air conditioners. Tui and his sons were able to run a new line to help distribute the electrical load, allowing us to run our AC units without constantly tripping the breakers. Their quick service, knowledge, kindness, and genuine care brought much-needed relief to us, especially in the heat. Beyond solving the electrical issue, they provided peace of mind and showed what it means to serve others with aloha. We are truly grateful for the work Tui and his sons did for our family. We highly recommend them to anyone looking for honest, dependable, and caring electrical service. Mahalo nui loa, Tui to you and your sons!"

"The job is half complete, they are waiting for HEC to confirm when electric can be turned off to finish the job of installing a meter on the outside of the house. So far, their service and desire to help ground the electrical outlets has been very good."

Generator Install FAQs, answered by experts

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.
