Enter the DC Output and AC Capacity into the calculator to determine the DC to AC Ratio. This calculator can also evaluate any of the variables given the others are known.

## Dc To Ac Ratio Formula

The following formula is used to calculate the DC to AC ratio.

DC to AC Ratio = DC Output / AC Capacity

Variables:

- DC to AC Ratio is the Inverter Load Ratio (ILR)
- DC Output is the power output of the solar panels (Watts)
- AC Capacity is the power capacity of the inverter (Watts)

To calculate the DC to AC ratio, divide the DC output of the solar panels by the AC capacity of the inverter. A higher ratio indicates that the solar panels are capable of producing more power than the inverter can handle, potentially leading to energy loss. Conversely, a lower ratio indicates that the inverter has more capacity than the solar panels can produce, potentially leading to underutilization of the inverter.

## What is a Dc To Ac Ratio?

The DC to AC ratio, also known as the Inverter Load Ratio (ILR), is a measure used in solar energy systems. It refers to the ratio of the Direct Current (DC) power output of the solar panels to the Alternating Current (AC) power capacity of the inverter. A higher DC to AC ratio means that the solar panels are capable of producing more power than the inverter can handle, which can lead to potential energy loss. Conversely, a lower ratio means that the inverter has more capacity than the solar panels can produce, which can lead to underutilization of the inverter.

## How to Calculate Dc To Ac Ratio?

The following steps outline how to calculate the DC to AC Ratio:

- First, determine the DC Output (power output of the solar panels in Watts).
- Next, determine the AC Capacity (power capacity of the inverter in Watts).
- Next, gather the formula from above = DC to AC Ratio = DC Output / AC Capacity.
- Finally, calculate the DC to AC Ratio.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

DC Output (Watts) = 500

AC Capacity (Watts) = 400
