A backup generator is your first line of defense against power outages. After all, outages entail risks, such as security threats, frozen pipes, flooded basement, and spoiled food. As a homeowner, these are the last things you will want to deal with.
Fortunately, a backup generator can save you from trouble as it keeps the appliances up and running even when there is no power.
Skimping on the generator size sounds tempting as it can save you dollars, but you may end up spending on one that doesn’t even cover your basic needs. Moreover, your appliances and devices are at risk if you go too small.
Conversely, opting for a large machine increases the starting cost and fuel expenses. It is vital to choose wisely, and here is a size guide that can help.
Choosing the Generator Size

Understand Your Requirements
When it comes to choosing the size of the backup generator for your home, everything boils down to your requirements. Start by listing the devices you expect to run, determine the wattage for each piece, and calculate the total power requirement by adding them up.
You will get a fair idea of the minimum wattage needed to support the appliances and ensure that they run smoothly. Opting for a generator that does not deliver enough wattage is a bad idea as your devices are likely to get damaged.
Examine Generator Performance
Calculating your power requirements gives you a good start because you have a clear idea of what you are looking for. But you also need to examine the performance of the generator you plan to buy to cover your requirements.
It isn’t as technical as it sounds because manufacturers provide performance charts to help buyers assess the product. Before you go ahead with generator installation, ensure that the chosen unit comes with the necessary power rating to run the appliances you want.
Generators are rated in kilowatts and come in different capacities, so it makes sense to research a bit before you buy. Alternatively, you can seek expert opinion from a professional, for example if you want a powerful, yet quiet generator.
Consider Outages in Your Area
This one is a no-brainer, as long and frequent outages will require investment in a bigger size. You will not want to run out of power in the middle of an extended outage every now and then only because you picked a smaller generator.
Before you opt for a unit, consider the frequency of severe weather events, such as hurricanes, blizzards, and ice storms in your area. Some locations are more likely to have outages than others, even when the weather is not a concern.
Keep track of the outage pattern and consult an expert regarding the choice of the unit. They can assess your requirements better because they have the right expertise and experience.

Final Thoughts on a Backup Generator
A backup generator keeps your living space safe and comfortable even during extended power outages. But you must spend wisely because it is a considerable and long-term investment. Opt for the apt size because it determines the value you get from the unit.
