When buying a generator, it is essential that you purchase the right size to avoid issues like insufficient power supply, unit failure, or capacity overload. Choosing the wrong size won’t provide you with the adequate power or efficiency you need during emergencies. However, most homeowners don’t know how to determine the right size for their energy-efficient generator. If you are also in the same situation, fret not! We’ve got you covered.
Here’s our step-by-step guide to calculating the generator size for your home.
Step # 1: Calculate the wattage
The first step is to determine the total running wattage of your home. For that, you need to sum up the wattage of all the appliances and equipment in your home. All devices have wattage information written on them, or you can check with the manufacturer.
Step # 2: Calculate the power requirement
Once you have calculated the wattage needed to run the electrical appliances, you need to calculate the wattage for all the motors you have in your home and add them. If your sump pump or other heavy-duty motors require 600-800 watt motors, you need to multiply their wattage three times as they need that much power to kick start. Adding them all, you get your total power requirement.
Step # 3: Determine the surge wattage you need
Once you have the wattage requirements, you need to determine the surge rating you need for your generator. Surge rating determines how much power surge your generator can handle before it breaks down.
To determine the surge rating, you need to add your equipment’s highest surge watt rating, as sometimes the motor may run at a higher rate than the standard wattage. Then you need to add the total wattage and surge wattage to get the total surge wattage. Once you have the surge wattages, you can search for generators that support that much power requirement and surge wattage.
Step # 4: Find adequate generator cords
The generator cords you use are as necessary as the generator size. Use generator cords that do not have the carrying capacity when the generator is running. Your equipment may not get enough power, and you may also damage the generator. Hence, always find the right cords along with the generator.
Step # 5: Hire a professional contractor
If you find the DIY approach to calculating the right size generator too complicated and exhausting, the easy way out is to hire professional generator installers like Nebraska Generator Service. They can help you find the right generator according to the power requirements and also help install it correctly.
Why is finding the right generator size important?
Here are the problems you can face if you find the generator of the wrong size.
If you get one in a smaller size, it can cause:
- Generator damage or overheating
- Insufficient power supply
- Critical system failures
If you get one in a too-large size, it can cause:
- Damage to appliances
- Additional operating costs
- Inefficient power production.
Hence, both the scenarios are not favorable for your home and generator.
