Category: Solar & Battery

Amp hours become an energy quantity only when a voltage is supplied. Electricity units use kilowatt hours.

Enter the nominal battery values and select the conversion basis. Apply usable capacity and inverter losses in their own worksheets.

## Inputs and controls

* Known energy: Voltage and Ah to energy; kWh to required Ah
* Amp hours (Ah). Allowed range: 0 to 1000000000
* Energy (kWh). Allowed range: 0 to 1000000000
* Nominal voltage (V). Allowed range: 0.01 to 2000

## How to use

* Choose known energy. Enter amp hours, energy and nominal voltage.

* Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.


## Why use this tool

The converter provides a common nominal energy unit for comparing differently labelled capacities.


## Before relying on the result

One electricity unit means one kWh. Conversion is nominal energy only and excludes DoD, health, inverter losses and idle draw.


## Tool limitations

One electricity unit means one kWh. Conversion is nominal energy only and excludes DoD, health, inverter losses and idle draw.

## Questions

### Does one electricity unit equal one kWh?

Yes. This conversion uses one unit as one kilowatt hour, without deducting battery or inverter losses.

### What should I check before using Battery Energy Unit Converter?

Check Known energy, Amp hours, Energy and Nominal voltage. Use the exact units shown beside the controls and replace any example values with your own inputs.
