Volts to Amps

Find out how to calculate volts to amps to be more energy efficient and reduce the risk of electrical overload

Many homeowners naturally want to make sure their homes are safe and efficient to protect their family and property. Understanding electrical safety is crucial to minimize the chances of accidents or damage caused by electrical issues at home. Familiarizing yourself with basic electrical concepts like voltage and amperes (amps) can go a long way in ensuring your electrical system is both safe and cost-effective. You can use the volts to amps calculators online but it is also helpful to understand how these components work together. Let's explore these essential principles to help you create a secure and efficient environment at home.

Volts and Amps at Home

An easy way to remember what volts are is if you think about it as the force that pushes the electric current through a circuit. Amps or amperes on the other hand is the rate at which electric charge flows. Volts and amps work together to deliver electrical power to gadgets, large appliances, and other electrical devices. One helpful illustration is if you will think of this concept as the water and hose in your backyard. The force or pressure that pushes the water out of the hose is the volts whereas the amount of water that flows through the hose is like the amps in an electrical circuit. The amps tell us how much electricity is flowing.

The formula to calculate amps is:
I(Amps) = P(Watts) ÷ V (Volts)

Volts to Amps of Homes without Solar Panels

If you solely rely on the grid and don't have solar panels yet, you can calculate the amps by first finding each of your devices' power ratings in watts. You can look for the labels on the device itself, box, or user manual. The standard voltage for household outlets in most homes in the United States is 120 volts. However, it's essential to double-check your local voltage, especially if you're in a different country. 

If you already know the watts and volts you can plug in the values by using the formula mentioned earlier. You can repeat this calculation for each device or appliance to know how much current they use individually.

For instance, if you are setting up your home office and you are planning to plug multiple devices into one power strip that is rated for 120 volts and 15 amps, you can manually calculate the load of each device to ensure safety. This means that you need to check if all of the devices that you will plug in should not exceed 15 amps.

For this home office example, we can assume that a lamp operates with 60 watts and a computer with 300 watts.

You can calculate the amps used by a lamp and computer plugged into a standard 120-volt power strip by substituting the values in the formula as shown below:

Solving the Amps for the Lamp:

I(Amps) = 60 Watts ÷ 120 Volts = 0.5 Amps

Solving the Amps for the Lamp:

I(Amps) = 300 Watts ÷ 120 Volts = 2.5 Amps

This means that the lamp and the computer approximately consume 3 amperes of current to work.  This simple calculation shows that the combined load of the electronic devices is within the safe limits of the power strip. However,  if you need to determine a more exact measurement of the rated current for multiple devices that require more power, you can use tools such as the clamp ammeter or as some people call the "amp clamp" to measure the real-time current accurately. Keep in mind that you must always exercise caution whenever you deal with electrical devices or consider consulting with a professional if you have doubts or safety concerns.

Volts to Amps of Homes with Solar Panels

If you already have solar panels installed in your home, you can use the same formula 

but you need to know the output of your solar panels in watts. Solar panels generate electricity when exposed to sunlight. This output depends on factors like the size of your solar panel system and the amount of sunlight it receives. The solar panel installer or system specifications should have this information. For instance, Nature's Generator Powerhouse Gold System has two 410-watt power Panels which, as a bundle, can power multiple devices from laptops, and TVs, to refrigerators. It is powerful enough to serve as your whole home's power backup.

Keep in mind that solar panel performance can vary due to factors such as shading, temperature, and angle of the panels. To get a more accurate estimate of the amps your solar panels generate in real-world conditions, you may need to consult your solar system's monitoring equipment or consult with a solar professional.

Once you know the output of your solar panels in watts, you can calculate the total power consumption of your home by adding up the power ratings (in watts) of all the electrical devices and appliances you want to operate with the power from your solar panels.

For example, you want to power the following devices with your solar system:

  • 4 light bulbs with 60 watts each
  • refrigerator with 150 watts
  • computer with 300 watts
  • microwave with 1,000 watts

You just need to list down their power ratings in watts and add them all up to find their total power consumption as shown here:

Total Power Consumption = 240 watts (lights) + 150 watts (refrigerator) + 300 watts (computer) + 1,000 watts (microwave) = 1,690 watts

Next, you can use the same formula to know the current being produced by your solar panels and the current being used by the devices in your home as shown below:

For solar panels:

I(Amps) = Solar Panel Output (Watts) ÷ V (Volts)

For home consumption:

I(Amps) = Total Power Consumption (Watts) ÷ V (Volts)

When you have the approximate figures, you can compare the current produced by your solar panels to the current used by your home. If the current from your solar panels is less than the current that your devices need, you are drawing electricity from the grid or batteries to meet your needs. On the other hand, if the amperes for the solar panels are greater than your energy consumption, your solar panels are producing more electricity than your home is using, and you may be sending excess electricity back to the grid or storing it in batteries if you have a storage system. If you are looking into investing in a solar battery, you can check out Nature's Generator Eco-Intelligent Li or you can contact our support team for more information.

To recap, you can calculate the amps in a home with solar panels by:

  • Knowing  the output of your solar panels in watts
  • Calculating  the total power consumption of your devices
  • Comparing  the current produced by your solar panels to the current used by your home

These calculations can help you understand how much electricity your home consumes and how your solar panels contribute to meeting that consumption. It's important to monitor your solar system's performance regularly to ensure it meets your energy needs and to optimize energy usage and savings. You can also consult with a qualified electrician or solar panel installer to ensure that your solar panel system is safely integrated into your home's electrical system.

Understanding how volts and amps work is essential because it allows you to ensure that your electrical system is compatible with the devices or appliances that you use at home. It can also help reduce your electricity bill because you will have a better understanding of how you can be more efficient in consuming electricity from the grid or your whole-home solar system.
