Purpose

This guide explains how to reduce the ramp‑up time (faster power increase after start or grid recovery) on Kostal inverters using the Kostal web interface / app. The screenshots provided are used as reference.

⚠️ Important: Grid‑related settings are usually restricted by local grid codes (e.g. BE C10/11). Only certified installers should change these values. Always comply with local regulations.

Step 1 – Log in as Installer (required)

Many ramp‑up and power gradient parameters are not visible unless you are logged in as Installer.

  1. Open the Kostal interface and go to Settings.
  2. Select User management.
  3. Log in using the Installer credentials.
  4. Confirm that you now see advanced settings such as Grid settings and Power adaptation/controls.
