Your electric dryer might have a low priority and the well pump a high priority. Some of the newer power management systems allow priorities to change as needed with a convenient smart phone app. A whole house generator with power management installation uses a smaller generator that costs less to purchase and install and uses less fuel than the larger liquid-cooled models. By feeding the main circuit breaker panel from the generator, the whole house generator powers everything including major and large appliances like Electric Ranges, HVAC, and Water Heaters.
Whole-House Generator Cost by Type of Fuel
Persistent overloads can burn the motor and generator windings, causing damage and failure. Depending on their BTUs or tons, HVAC systems can be several different sizes, drastically affecting the generator size that is appropriate for your house. Refer to your HVAC unit’s user manual for more information on the total system wattage needed to power it. Central heating and air conditioners use more electricity than any other devices in your home, so it’s important to get an accurate measurement on this device as well. The key goal of how to size a generator is to figure out the running and starting wattages. When you have done that, you can choose a generator that matches (or goes beyond) that wattages the closest.
#3 Sum All Running Wattages And Add The Highest Starting Wattage
There’s also a balance between power and cost – high-powered generators are significantly more expensive. For some appliances, you can look at the data tag and calculate the running watts required to power the device. To calculate the operating wattage, multiply the amperage by the voltage. For a microwave that requires 13.4A and 120V, the operating wattage would be 1,608 watts.
Inverter Generators
In our case, that’s either the 2,200W starting wattage fridge/freezer or 2,200W starting wattage window AC. That’s why we have prepared a sample table (you will find it below) of average wattages for home appliances, camping appliances, RV and camper electric devices, and so on. Running watts are the electric power an electric device needs to operate continuously. Usually, we have no problem finding a generator with enough running wattage to power all our devices. Having an emergency standby generator in a home, particularly homes of higher value in Southeastern Wisconsin, is becoming an expectation nowadays.
Homeowners who have breathing machines, respirators, home dialysis machines, or other power-assist devices in their homes know that power loss is a matter of life and death. A whole-house generator, even a smaller one that only powers the medical devices, is crucial in this case. Sump pumps are an automated way to keep basements and low-lying areas of the home from accumulating water or flooding—at least if they have power. Part of a whole-home generator installation is installing a permanent resting spot.

An essential power standby generator uses less fuel than one powering the entire home. Only powering essentials lowers the electrical load—important for installations that rely on a propane tank for fuel. In the middle of winter, the generator may have to share the propane supply with the furnace. Whole house generators produce enough power to handle everything in your house at the same time.
” will want to consider how frequently they anticipate needing backup power. Those who experience frequent and prolonged power outages may choose a large inverter or a home standby generator, also known as a whole-house generator. The size of a whole-house generator can vary, but most will be able to provide enough energy to power an entire home.
A home in the Desert Southwest probably uses more power in the summer than a house near the northern border. An important part of sizing includes local building codes which may include requirements not listed here. A whole house generator for a small home might only have enough capacity for essentials at a large home. A whole house generator with power management for a large home is probably more power than a small home needs. If a portable generator is adequate, most homeowners can prepare the generator before an anticipated outage or get it running pretty quickly after an unanticipated one. However, a larger standby or backup generator is not a DIY installation.
What Generator Size Will Work Best for Your Home?
These generators can save homeowners money if they don’t mind having a generator stored in a shed or garage and manually hooking it up during a power outage. Large inverter generators are efficient and quiet but can be expensive. Some large portable generators can be connected to a breaker panel, and they’re louder than a large inverter generator.
Homeowners can compare portable vs. standby generators to find which would work best for their home. For someone who rarely loses power but wants peace of mind just in case, a recreational inverter or a midsize inverter generator has enough power to run a few essential items. These portable models can also be used for tailgating to power a cooktop or a TV.
Natural gas is the most common type of fuel for whole house generators. It's a bit more expensive than natural gas, but it's easy to store and transport. It's more expensive than natural gas and propane but has a longer runtime.
They can be connected directly to the home’s circuit breaker panel to run devices that are hardwired in the home and are essential during a power outage, such as a water heater, HVAC unit, and sump pump. A generator specialist will determine the right size generator for the home, and they’ll complete the wiring job. These generators can be permanently installed and will automatically kick in when there’s a power outage to provide seamless energy. It may also be worthwhile for a homeowner to invest in one of the best generator covers to extend the lifespan of the unit.
When in need of temporary power for medical, heating, cooling or electrical reasons, Angi’s electricians can help. For example, you may need to keep your refrigerator, freezer, well pump and lights running continuously and charge your laptop or use your microwave on top of this. Since September 2020, she has been offering readers advice about general home improvement, kitchen renovation, service and product costs, and repairs.
