Whole Home Generators

Stay your house prepared for power outages

What is A Whole Home Generator and How does it Work?

A whole home generator, also known as a standby generator, is a backup power system designed to automatically power the entire home during a power outage.

Whole-house generators provide backup power during a power outage and their working principle mainly includes the following steps. When the power grid is out, the generator detects the power outage through the built-in automatic monitoring system, immediately starts and prepares to supply power. The generator is then connected to the home circuit through a transfer switch or smart distribution panel to ensure that all electrical devices are quickly restored to power.

For solar whole-house generators, it uses solar panels to capture sunlight, convert it into electricity, and store it in large-capacity batteries for later use. This system not only provides stable power support, but also effectively reduces the family's energy bills and promotes the use of renewable energy.

Home Solar Generator vs. Home Standby Generator

Home standby generators are typically fueled by gas or propane and provide immediate power during outages, automatically starting when needed. They are reliable for high power demands but require fuel storage and regular maintenance. In contrast, home solar generators harness sunlight through solar panels, converting it into electricity stored in batteries. They offer a sustainable, renewable energy source, reducing electricity bills while providing backup power. Solar generators have lower operating costs over time but may require sunlight to recharge.

FAQ

How to Choose A Whole Home Generator

Determine Your Power Needs: Assess your home's essential appliances and systems-like HVAC, refrigerator, lights, etc.-to calculate the total wattage required during an outage. Generators are generally sized by their power output, so select the one matching your energy needs.

Standby vs. Portable: Determine whether to purchase a standby generator that will automatically provide power to one's home during an outage or a portable model that requires the manual setup of the device. Standby generators are permanently installed and offer greater convenience and reliability.

Fuel Type: Determine the fuel type with which the generator is designed to run; common types include natural gas, propane, diesel, and solar. Choose among these according to their availability, cost, and environmental impact. For example, natural gas supplies fuel continuously if it's available in your home.

Runtime and Efficiency: These generators run on efficient fuel consumption with longer run times, which is important in extended power outages.

Noise Level: If it is to be placed near living areas, then look at the decibel rating. Some models offer quieter operation, and that may be of importance for residential areas.

Automatic Transfer Switch (ATS): If a generator has an automatic transfer switch, it will, without requiring human intervention, switch the power from the grid to the generator upon an outage. That convenience is vital to make sure your home is powered up really fast.

Budget and Installation Costs: Besides the cost of the actual generator, consider how much installation will cost-for example, labor and permits for a standby unit. Indeed, more money means more features-think weather resistance or Wi-Fi monitoring.

Brand and warranty: Every owner wants a well-renowned brand that would provide decent customer support; warranty coverage is necessary. A good warranty will provide long-term peace of mind for maintenance and repairs. By considering these factors, you can select a whole home generator that suits your specific needs, ensuring reliable power during outages.

Is a whole house generator worth it?

Generally speaking, a whole-house generator will be worth the investment for those living in areas where power outages are very frequent, utilize important equipment, and are looking for additional value and security for their homes. If the home is in an area where there are few power interruptions, such a high cost may not be reasonable. That just depends on your priorities for convenience, safety, and long-term savings.

Can a portable generator power a whole house?

A portable generator can run an entire house, but there are some important considerations. Because portable generators have a tendency to supply less wattage than standby generators, they may not be able to operate all of a whole house's electrical needs at one time. The following procedure is for using a portable generator with whole-house power:

Choose the Right Size: Portable generators are designed in various watt sizes, spanning from 3,000 to 10,000 and upwards. To power up your house, at least during an outage, you would want a higher wattage model at least 7,500 watts. It may well keep on essentials like lights, a refrigerator, and HVAC but cannot be kept running all together.

Selective Power Consumption: The portable generators have limited power output; hence, you have to manage the usage depending on which appliances or systems you employ at the same time. For instance, you can able to power up an essential device, but you cannot power up heavy-draw appliances such as an oven and central air conditioning together.

Transfer Switch: The installation of a transfer switch will connect the generator safely with your residential electrical panel, for reasons assured hereafter. The switchboard will enable you to transition smoothly between utility and generator power with no back-feeding-an occurrence very dangerous to utility workers and your home.

Setup Manually: While whole home standby generators automatically come on at the time of an outage, portable generators need to be set up manually by fueling, starting, and connecting to your home. In brief, a portable can power a whole house but often has some compromise in terms of which appliances you use at one time. A standby generally covers the whole home, and with complete coverage, it's often automatic.

Can a solar-powered generator power a house?

Yes, that is possible. A solar generator's ability to power your home depends on several factors, including the capacity of the generator, your home's energy needs, and the specific appliances and devices you want to power. This is achievable when it has an output power and capacity greater than what your appliances and equipment require.

While solar generators can currently provide backup power for certain essential appliances and devices in the event of a blackout or off-grid, they may sometimes not be sufficient to continuously power an entire home like a grid-connected solar system.

What size generator do I need to run my whole house?

To start with, your entire house needs identification of your home power needs and the appliances or systems that you would want to operate during a power outage. First, highlight all the important things you normally use inside the house, such as a refrigerator, HVAC, lights, and water heater, by computing their total wattage usage. For example, most refrigerators require up to 600 watts, while a central air conditioning unit may need between 2,000 to 6,000 watts. You also have to take into account surge power: the extra wattage needed to kick-start some appliances. In general, a generator in the range of 3,000-7,500 watts will cover partial home power, serving basic needs, while 7,500-10,000 watts will serve most average-sized homes. To serve a whole home, including major appliances such as air conditioning, generally a generator rated at 10,000-20,000 watts is needed. For large homes that demand high power, 20,000+ watts may be needed. Standby generators provide reliable, whole-house coverage with wattages ranging between 10,000 to 20,000 watts. In situations where partial use is intended, a portable generator would be far better. Consult an electrician to get the right size suitable for a particular unit of use.
