How does a power inverter work?

A power inverter is a device that converts DC from a battery into AC that can be used to power 120-volt electrical devices. The inverter is connected to the battery by a cable, and it is plugged into a 120-volt outlet to power the devices.

The inverter is a mechanical device that uses a very complex and powerful circuit called a pulse width modulator to convert the DC to AC. Power inverters can be designed to output many different types of current, including the current used in Europe.

Since the currently available in Europe is different than the currently available in the United States, you need to know your needs and select the correct type of inverter.

What to Consider Before Buying?


The first thing to consider is whether it can properly operate your pump. It’s pointless to buy an inverter that overloads as soon as the pump begins, flooding your basement. To avoid this, we’ll delve deeper into sizing in the following section.

When it comes to capacity, you want to make sure that the inverter can handle running your pump. This means checking the specs to see if the wattage and surge rating are high enough. Some pumps require more power than others, so you’ll want to make sure that the inverter you choose is up for the task.

Another thing to look at is how long the inverter will run your pump. If it only has a short runtime, that might not be enough for a big job. Conversely, if it has a very long runtime, you might not need a big inverter. It all depends on your needs.

Finally, you’ll want to consider whether the inverter has a built-in charger.

Power type:

There are two types of Power Inverters to choose from:

  • Modified Sine Wave Power Inverter
  • Pure Sine Wave Power Inverter

Modified sine wave inverters have a cheaper price tag, but they also come with their share of problems. Their low-quality output can result in slow starting motors, noisy operation, and even damage to your appliances.

If you want to be sure that you’re getting the most out of your inverter, go for a pure sine wave option. These inverters are more expensive but they produce a clean, consistent power signal that is safe for all electronics. They also start up motors quickly and quietly, making them a great option for any job.


In addition to the basics, there are a few extra features that you might want to look for when choosing an inverter.

Some inverters come with built-in USB ports or cigarette lighter adapters. This can be handy if you need to charge your phone or run another small appliance while the pump is running.

Others have digital displays that show you how much power is being used and how much runtime is left. This can help decide when to shut the pump off.

Finally, some inverters have a built-in alarm system that goes off if the voltage or wattage gets too high or low. This can help protect your pump from damage.

Frequently Asked Questions:

How to size an inverter for your pump?

When you are choosing an inverter for your pump, you need to consider the wattage of the pump. You will also need to consider the starting power of the pump. The PowerVerter APS1250 has a starting power of 3750 watts and a continuous power of 1250 watts. This inverter is perfect for those who have a soft starting pump. The Power Inverter WZRELB has a pure sine wave power output of 2000W. This Power Inverter is perfect for those who have a hard starting pump.

The only way to know if an inverter can operate your pump is to verify the current capacity. It’s usually located on the nameplate at the top. If you know what type of pump you have, you may look it up on the internet.

Let’s suppose your pump is operating and the starting current is 5A, while the running current is 15A. The result of each of them multiplied by 120V is 600W and 1800W. You’ll need an inverter with the capacity to handle that amount of power.

The PumpSentry 822 PS or the PumpSpy backup inverters have a capacity of 1200W. You’ll be able to run the pump with no problem and you can even add additional devices to that inverter.

How to size the battery:

When it comes to the amount of power required, consider a 100-gallon or larger pond pump. A 5A/120V pump uses 600 watts. To achieve a tenth of the voltage at 12V and 10 times the current at 50A, you’ll need ten times as much power. You’ll need a 75AH battery to keep the pump running for 24 hours.

The greatest choice would be a deep cycle battery. It works best with sump pump load patterns. Don’t use automobile batteries because they are not appropriate for usage. Also, make sure your cables are rated to handle the proper amount of current flow through them. The manual usually contains the recommended size.

Steps to install a power inverter for the sump pump:

  • Make sure the outlet is grounded
  • Check the circuit breaker to ensure that it is working
  • Connect the inverter to the circuit and test the inverter to see if it works
  • Connect the wires to the inverter and the sump pump
  • Attach the sump pump to the wires and connect the wires to the power inverter
  • Connect the wires to the sump pump
  • Test the sump pump to see if the inverter has worked
  • Connect the power cable to the power source
  • Test the sump pump to ensure that it works
  • Disconnect the wires from the outlet
  • Remove the cover of the outlet to expose the wires
  • Remove the cover of the power inverter
  • Attach the wires to the outlet and the power inverter
  • Test the sump pump to ensure that it works
  • Turn off the switch when not in use

Why use a power inverter instead of a battery backup pump?

Power inverters are much more economical for turning DC power into AC power. It is estimated that you will save about $1,000 in the lifetime of your purchase by using a Power Inverter instead of buying an expensive battery backup pump system.

Power inverters can take care of up to 900 watts which many pump brands recommend as the minimum wattage to handle their specific models accurately. Some models have built-in transient protection which can save time and money when installing or moving houses unnecessarily.

Another great benefit is having two pumping systems available with the Power Inverter so if one fails, there’s another one intact to take care of any issues.

Is this like a UPS for sump pumps?

A UPS, or Uninterruptible Power Supply, is a device that provides emergency power to a computer or other electronic device in the event of a power outage. A Power Inverter for a Sump Pump is not exactly like a UPS, but it serves a similar purpose.

A power inverter takes DC power (from batteries or solar panels) and converts it into AC power, which can be used to run devices like sump pumps. If you have a Power Inverter for your sump pump, you will never have to worry about losing power during a storm and having your basement flooded.


When it comes to choosing the best power inverter for your sump pump, there are a few things you need to take into consideration. The first is the size of the inverter. It needs to be able to handle the starting current and running current of your pump. The second is how large of a battery you will need to keep the pump running for an extended period. And lastly, you need to make sure that your cables are rated to handle the amount of current flowing through them.
