Understanding Whole House Generators
Be it a blizzard, snow, tornado, or flood – nature is not under the thumb, and for that reason, a reliable power supply is a must for the well-being of your loved ones. We do rely on electricity for almost everything nowadays, and the consequences of power failure can be far-reaching. There is an entire list of unpleasant situations you may encounter when the power fails, such as no lighting, no cooking, no cooling or heating, no refrigerator or water pumps, and no work being done. These are just a few examples of the possibilities when there’s no electricity at home, so when the power goes off, the generator steps in as the electricity source.
What is a Whole House Generator?
A whole-house generator is a backup power system designed to provide electricity to the entire residence during a power interruption. These devices are permanently installed outside the house, and they are connected directly to the electrical system, unlike portable generators. The whole-house generators are equipped with an automatic transfer switch for uninterrupted power distribution when the leading utility fails. I have come across these generators in different sizes, some of them being able to provide power only for the basic needs such as refrigerators, air conditioning systems, and lights, while others can completely supply power to a big household. The new generation is amazing, silent, fuel-efficient, and monitored. Hence, they are a reliable power source during blackouts, which is essential for our daily lives. However, installing a whole-house generator provides a sense of peace of mind and ensures that your house stays operational even if the power is cut.
Benefits of a Whole Home Generator
Uninterrupted Power Supply
A generator system installed in an entire home guarantees that the energy flow in your house won’t be disturbed even during conditions when the electrical grid is down. Power outages have hit an all-time high in the USA, with more than a 70% spike in frequency over the last decade, proving the increasing usefulness of backup generator systems.
Protection for Essential Appliances
The generator systems are generally configured only to power up the most essential appliances like refrigerators, HVAC systems, medical devices, and lighting. This is to avoid the aforementioned omniscient critical scenarios.
Enhanced Property Value
The market value of properties with a backup power generator rises. According to the real estate data, properties with the above systems are much more desirable and therefore would fetch a higher price when sold.
Fuel Efficiency and Cost Savings
From an energy perspective, modern generators for a complete house are much more fuel-efficient, meaning they require less gas or propane to produce energy stably. Hence, the cost of running these generators is less than that of older models or portable generators, in addition to the benefit of lower emissions.
Convenience and Automation
Considering the state-of-the-art technology, these systems can identify the problem in an instant and immediately start up, cutting the trouble of booting up a manually placed standby generator. In addition, a lot of the machines can be controlled through a smartphone application over the internet.
Weather Resilience
When compared to portable generators, home standby generators are made and designed to be exceptionally weatherproof, allowing them to operate during hurricanes, storms, or freezing conditions. This durability is also essential in areas where the weather is likely to be destructive.
How Does a Standby Generator Work?
Every time there is a power outage, a generator in a “dormant” state feels the problem thanks to the transfer switch. When this happens, it sends a start signal to the generator along with a portion of the house’s energy, with the grid previously being the source. After that, the generator delivers energy through its internal combustion engine, which runs on natural gas, propane, or diesel, among other fuels. As we mentioned, the generator serves as the provider in this case. When the utility power is back on, the transfer switch changes the source back to the grid, shuts down the generator, and then returns to standby mode. As far as the source of the power is concerned, very few conditions occur for such generators. That is because the seamless operation of these generators ensures the continuous provision of the standby power. They can only be equipped with the latest technology, allowing for precise control and monitoring of their functions. Such standby generators operate without any issues during outages, and they meet all the stringent industry requirements in accordance with applicable standards.
