There are several things you will need to consider when figuring out the size of your whole house generator. These include the square footage of your home, the total power requirements of your appliances, and other factors.
Calculate the total power requirement for appliances
If you are planning to buy a whole house generator, you should consider the power requirements of your appliances. A good start is to make a list of all the appliances in your home. Then, you can add them up and get a general idea of what size generator you should purchase.
Most electrical appliances are rated in watts or amps. Watts are equal to the current drawn by an appliance multiplied by the voltage used. It is easy to find out the wattage of an appliance by checking the label or nameplate.
Many electrical appliances have a range of settings, so the actual wattage of a product may vary. For instance, a radio set at high volume uses more energy than a radio set at low volume. You can use a wattage calculator to estimate how much power is needed for a particular appliance.
Appliances can be grouped into two categories: resistive loads and motorized loads. Reactive loads have lower power demands when they are off, and motorized loads have higher power demands when they are turned on.
Determine your home’s square footage
When you’re in the market for a whole house generator, the size of your home plays an important role. If you don’t know how big your home actually is, you may end up getting one too small to power your whole household. This can also have an impact on your property tax bill. The best way to go about figuring out your home’s square footage is to take measurements of your room sizes, such as the width and length.
For example, if your floor plan is an L shaped house, the easiest way to measure the size of your rooms is to measure the width and length of each wall. You can then add the dimensions together to get the room sizes.
A whole house generator is a good investment if you live in an area that’s regularly hit by tornadoes, hurricanes or other storms. However, a unit that’s too large for the job can waste fuel and waste precious resources.
Calculate the starting wattage required
When you are buying a whole house generator, it is important to calculate the starting wattage required. This is because appliances in your home may require different power sizes. Using the appropriate calculator can help you determine the proper wattage for your household.
The most common type of load is the inductive load, a load generated by coils of wire. Other types include the resistive load, which is a load generated by moving parts. There are also the motorized and electrical loads, which are both reactive.
To calculate the starting wattage required, you can use the formula of starting current x voltage for watts. For example, the starting wattage for a 600 watt motor is 1,800 watts.
Running watts are another important measure. These are the maximum watts your generator can deliver while it is running. You can calculate these numbers with a wattage calculator or by reading the owner’s manual.
It is not uncommon for some appliances to require more starting watts than running watts. Refrigerators and air conditioners are just two examples.
Consider other factors that affect the size of your generator
If you live in an area prone to storms, installing a whole house generator is a smart investment. However, it is important to consider other factors when determining how large a generator you will need. For example, the square footage of your home will determine how much power you need. Also, you’ll need to decide how many appliances you’ll need to run with your generator. These include items like lights, security systems, and high-wattage items such as microwaves, water heaters, and clothes dryers.
You’ll also want to factor in how often you plan to use your generator. The more power you need to run your home during an outage, the larger your generator will need to be. This is especially true if you live in an area prone to prolonged blackouts. To calculate your power needs, check your owner’s manual or your generator’s manufacturer for wattage requirements.
If you’re still not sure what you need, you can always contact an electrician to get a rough estimate. Remember, you don’t want to overdo it. It’s best to choose a generator that is slightly larger than you need.
