# Create Inverter (JSON)

> Create an inverter from a JSON request body

# POST /inverters/json

Create a new inverter by providing structured JSON instead of uploading an `.ond` file. This is useful when inverter specifications are already available in your application or when programmatically building an inverter library.

## Notes

* Requires a valid JWT with write access to the workspace.
* The request body must include `name` (non-empty string) and `properties` (dict of inverter specifications). The `efficiency` field is optional.
* The `properties` dict should contain the same key-value structure produced by `.ond` file parsing (Pnom, Vmax, efficiency parameters, etc.).
* Extra fields beyond `name`, `properties`, and `efficiency` are rejected (`400`).
* For uploading a PVsyst `.ond` file directly, use `POST /inverters` instead.
