# AC to DC Amperage Conversion Calculator: How to Convert AC Amps to DC Amps Through an Inverter

If you have an electrical household device that you need to run but have no regular grid power available, you’ve come to the right place. Keep in mind that this should not be confused with a converter, which takes AC to DC.

Our AC amps to DC amps conversion calculator can help you convert electric currents from an alternating current (AC) to a direct current (DC). For this, you need a DC-to-AC power inverter that takes the DC voltage a battery provides and inverts it to AC voltage so that you can run an AC-powered device.

Read on to learn how to convert AC to DC with our voltage-to-amperage calculator.

## AC to DC Conversion Calculator

The first step to sizing a battery pack when using a DC to AC power inverter is to know your DC amp rating. Our calculator will help you determine the DC amperage as it passes through a power inverter and provides the wattage rating you are pulling so you can properly size the power inverter you need.

Just enter your AC voltage and AC amperage into the fields below and we will do all the hard calculations for you. Note: This calculator includes the typical inefficiencies to give you a realistic DC amperage rating.

## FAQs about DC and AC Conversions

### How does DC work?

DC power flows is unidirectional, meaning electrons only flow in one direction through the wire to the device it is powering. Once at the device, the DC power is used and will then continue through the device and complete the circuit.

### How does AC work?

The electrical current in AC power works by periodically changing direction in a circuit at regular intervals. It’s the most common form of electrical power used for creating and distributing electricity to supply houses and businesses.

### How to convert DC to AC?

DC to AC conversion involves using a device called an inverter to convert DC voltage to AC voltage. Inverters consist of switches, transistors, and other components to regulate the flow of the current.

### What are the differences between DC and AC?

In DC, the electric current flows solely in one direction, whereas in AC the power changes direction.

### Do I need a DC to AC Inverter

For homes or businesses that are off-grid and are powered via solar power, or you need to use an appliance that requires AC power but is not connected to the electric grid (e.g., you rely on batteries or power banks), you will need a DC to AC inverter.

### What inverters convert DC to AC the best?

Battery Stuff offers a large selection of exceptional DC to AC converters, including highly rated pure sine wave power inverters, which help to prevent short circuits, overloads, and overheating.

### Can all DC to AC Inverters convert AC to DC if used in reverse?

Unfortunately, No. In a DC-to-AC inverter, the energy only flows one way. If you want to convert AC-to-DC, then you would need a charger or a charger converter/power supply. A battery charger takes the AC voltage and converts it to DC and chargers a battery or battery pack. For those trying to run a load with or without batteries, they will need a charger converter/power-supply. Converters are popular in RVs and boats, where you plug into AC shore power to charge a battery pack while at the same time running a DC load, such as your water pump, fan, or other accessories.

### Where can you buy a DC-to-AC converter?

We offer an extensive selection of top-grade DC to AC converters — and unlike some of our competitors, we stock all major brands in our state-of-the-art 14,000-square-foot facility. Browse our collection.
