# Create Inverter (File Upload)

> Create an inverter by uploading a PVsyst .ond file

# POST /inverters

Upload a PVsyst `.ond` file to create a new inverter in the workspace. The server parses the file to extract inverter properties (Pnom, Vmax, efficiency parameters, etc.) and efficiency curves, then stores the inverter.

## Notes

* Requires a valid JWT with write access to the workspace.
* The request body must be `multipart/form-data` with a single `file` field containing the `.ond` file.
* The inverter name is derived from the uploaded filename (without the `.ond` extension).
* Returns `400` if the `.ond` file cannot be parsed.
* Properties are stored as a flexible key-value dictionary reflecting the PVsyst file structure.
* If you already have structured inverter data and do not have an `.ond` file, use `POST /inverters/json` instead.
