When it comes to ensuring uninterrupted power in your home, especially during outages, the importance of choosing the correct size generator cannot be overstated. This article will guide you through everything you need to know about what size generator do I need for power needs.
Whether you’re facing repeated power outages or just want to be prepared, understanding the power-requirement and the type of generator suitable for your home is crucial.
What Size Generator Do I Really Need?
What size generator do I really need? The size of the generator you need depends largely on your power-requirements. Calculating the total wattage of appliances you need to run simultaneously is the first step.
For example, if you want to power essentials like a refrigerator, lighting, and a heating system, you’ll need to add up their wattage requirements. This will give you a baseline for the size of generator needed.
Mathematics Behind Generator Size Measurement?
To determine the size of the generator you need, you can follow a simple mathematical calculation. Here’s a step-by-step guide:
List Your Essential Appliances: First, list all the essential appliances and devices you want to run on the generator. This typically includes refrigerators, lights, heaters, air conditioners, computers, etc.
Find the Wattage of Each Appliance: Look for the wattage of each appliance. This is often found on a label on the appliance or in the user manual. There are two types of wattages to note:
Running Watts (or Rated Watts): The continuous watts needed to keep the appliance running.
Starting Watts (or Surge Watts): The extra watts needed for a few seconds to start motor-driven products like refrigerators or air conditioners. This is usually higher than the running watts.
Calculate Total Wattage: Add up the running watts of all the appliances. This will give you the total running watts you need.
Account for Starting Watts: Identify the appliance with the highest starting wattage. Add this starting wattage to the total running watts of all other appliances. This sum will give you the maximum wattage your generator should support.

Here’s an example calculation:
- Refrigerator: 700 running watts, 2,200 starting watts
- Lights: 300 running watts (total for all lights)
- TV: 200 running watts
- Laptop: 50 running watts
Total Running Watts: 700+300+200+50=1,250
Maximum Wattage Required: 1,250 (total running watts) + 2,200−700 (additional starting watts for the refrigerator) = 2,750 watts
So, you would need a generator that can handle at least 2,750 watts.
Remember, it’s always a good idea to have a bit of extra capacity, so consider a generator with a slightly higher wattage than your calculation. Also, for appliances with motors, like refrigerators and air conditioners, using the higher starting wattage in your calculations is crucial to ensure the generator can handle the initial power surge.

Why Power Outage Preparedness Matters
The outage of Power can happen unexpectedly and can be a major inconvenience. Having a generator that can provide power to your essential appliances ensures that your home remains functional and safe during these times. It’s not just about comfort, but also about preventing potential losses, like food spoilage. The size of the genset depends on the total wattage of the appliances you want to power.
When you are looking for a generator to power your house, you need to know about generator sizes and how they affect your power needs. The size of the generator is measured by the amount of power it can provide, which is usually expressed in watts or kilowatts.
The more power you need to start and run your appliances, the big a generator you will need. You can use a whole-house generator sizing guide to calculate how much generator power you’ll need to power your home. You also need to consider when choosing a generator the type of fuel it uses, the noise level it produces, the maintenance it requires, and the safety features it offers.
Some generators run on natural gas, which is convenient and clean, but may not be available in some areas. Others run on gasoline, diesel, or propane, which are more widely available, but may be more expensive or polluting. You also want to select a generator that can run for a long time without overheating or needing refueling.
A generator that is too small may not be able to handle the load on the generator, and may damage your expensive electronics. Maybe a generator and your expensive appliances are damaged.
A generator that’s too big may produce more power than you need, and may waste fuel and money.
The best generator for your home use is the one that can provide enough power to run the devices you need, but not more than that. A generator that can run efficiently and safely will keep your home comfortable and secure in case of a power failure.
