Enter the inverter power (watts), the inverter voltage (volts), and the power factor into the calculator to determine the Inverter Current.

## Inverter Current Formula

The following formula is used to calculate the Inverter Current.

I = Pi / (Vi * PF)
• Where I is the Inverter Current (amps)
• Pi is the inverter power (watts)
• Vi is the inverter voltage (volts)
• PF is the power factor

To calculate the inverter current, divide the inverter power by the product of the inverter voltage times the power factor.

## How to Calculate Inverter Current?

The following example problems outline how to calculate Inverter Current.

Example Problem #1

1. First, determine the inverter power (watts). In this example, the inverter power (watts) is determined to be 40 .
2. Next, determine the inverter voltage (volts). For this problem, the inverter voltage (volts) is measured to be 85 .
3. Next, determine the power factor. In this case, the power factor is found to be 74.
4. Finally, calculate the Inverter Current using the formula above:

I = Pi / (Vi * PF)

Inserting the values from above and solving yields:

I = 40 / (85 * 74) = .0063 (amps)

Example Problem #2

Using the same method as above, determine the variables required by the formula. For this example problem, these are:

inverter power (watts) = 10

inverter voltage (volts) = 50

power factor = .4

Enter these given values into the calculator or above yields:

I = 10/ (50* .4) = .5 (amps)
