# Energy system validation

**In this document**

You'll learn how the Energy system designer's validation tool checks for compatibility issues (matching transformer/grid voltage, phase compatibility, and other electrical requirements), how it runs automatically on every design change or save (and can be triggered manually via System → System validation), how to interpret the validation status icons (needs changes, may affect results, no issues) and act on the guidance provided, and how to disable automatic validation via the Auto-update design setting for smoother editing of large power plants.

## Energy system validation

The energy system designer offers many customization tools, and users may inadvertently misconfigure it, potentially leading to compatibility issues.

The **system validation tool** helps you identify such issues quickly. Its advanced algorithm checks factors like matching voltage on transformers and the grid or compatibility of phases. The system validation tool will indicate what needs to be changed to make the system compatible and viable.

## Activating system validation

System validation is triggered every time you make **changes** to the design or when you **save** your project. If you want to validate the system manually, navigate to the **System** and select **System validation**. The validation result will show on the screen.

For every calculation, there’s an indicator with the actual operation being performed and its progress is indicated with a progress bar, shown in the screenshot below.

## Validated parameters

You can examine the validation results by clicking the **System validation**.

This insight indicates what you need to change to ensure the system passes validation. To fix the issues in this case, you need to:

- **Select inverters with the same Vac** for all inverter setups.
- **Decrease the string size** per inverter in the array settings.

> [!TIP]
> **Note**: You can save an invalid design and return to it later to fix the issues. Minor issues may still allow you to execute the simulation.

## Deactivate automatic system validations

To disable the automatic system validations, navigate to **System** and uncheck the option **Auto-update design.**

> **Tip:** Diabling atutomatic system validations, allows to make several changes without triggering the automatic validation after each step, keeping the interface responsive when working on very large power plants.
