A solar power optimiser uses conversion and control at a selected module or input level.

## In plain English

### What does Photovoltaic power optimiser mean?

A solar power optimiser uses conversion and control at a selected module or input level.

### A simple example

A module-level optimiser can adjust its operating point within the chosen solar architecture.

### What the drawings help you do

Locate the optimiser between its selected solar input and downstream DC arrangement. It uses conversion and control near the module or input it serves. Show the downstream inverter as a separate function unless the selected equipment documentation explicitly combines the roles.

### Before using this reference

- Identify the module or input served by the optimiser.
- Reference the supported downstream equipment and communication.
- Show the selected input/output polarity and installation arrangement.

### Does an optimiser produce grid AC?

An optimiser is generally a DC-side conversion and control function. The equipment that creates the final AC interface must be identified separately for the selected system.

### Terms

- Optimiser: A conversion and control function applied to a selected solar input.
- Downstream: The next part of the electrical path receiving its output.

## How to read it

- Identify the module or input served by the optimiser.
- Reference the supported downstream equipment and communication.
- Show the selected input/output polarity and installation arrangement.
- An optimiser is not necessarily the equipment producing the final AC connection.

## Information to show or reference

- Identify the module or input served by the optimiser.
- Reference the supported downstream equipment and communication.
- Show the selected input/output polarity and installation arrangement.

## Important distinction

An optimiser is not necessarily the equipment producing the final AC connection.
