## Inverter Power Formula

The following formula is used to calculate the Inverter Power.

**Pi = RP * E/100**

- Where Pi is the Inverter Power (watts)
- RP is the rated inverter power (watts)
- E is the efficiency (%)

## How to Calculate Inverter Power?

The following two example problems outline how to calculate the Inverter Power.

**Example Problem #1:**

- First, determine the rated inverter power (watts). In this example, the rated inverter power (watts) is measured to be 89.
- Next, determine the efficiency (%). For this problem, the efficiency (%) is calculated to be 60.
- Finally, calculate the Inverter Power using the formula above:

Pi = RP * E/100

Inserting the values from above and solving the equation with the imputed values gives:

Pi = 89* 60/100 = 53.4 (watts)

**Example Problem #2: **

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

rated inverter power (watts) = 5

efficiency (%) = 2

Entering these values into the formula or calculator above gives us::

Pi = 5 * 2/100 = .10 (watts)
