Whether at home or on the road: the KOSTAL Solar App makes your energy flows visible and understandable. You can see at a glance how your PV system is working, how much electricity you are using yourself and how your electric vehicle is being charged. Intuitive to use, clearly presented - for more independence and a good feeling with every kilowatt hour.

The most important functions:

Plant list - The central starting point
The new plant list presents all plants in a clear and modern way. In phase 2, it will again be possible to create new systems.
Dashboard - the heart of the app
The new dashboard provides a clear, intuitive overview of the entire energy balance. The modern visualised energy flow and the flexible floating date picker (integrated and "floating" date selection for day, month and year views) allow you to switch quickly between time periods and analyse your system transparently.
Device list - all components at a glance
All devices in the system, visualised, with image, firmware and status. You can use this list to access your devices in the home network. In later phases: detailed device views, remote access, analysis functions.
App settings - simple, clear, self-explanatory
The app settings enable simple, self-explanatory management of all central areas. This includes your KOSTAL Solar Terminal account information, general app settings and data protection options. There is also a direct link to the KOSTAL ticket system for quick help.
Wallbox charging mode in the app
With the wallbox charging mode, you can control central charging functions of your wallbox directly via the app. The various charging modes can be conveniently switched and flexibly adapted to your individual requirements. The web server interface is still available for further or detailed configurations.

Stylish: the new dark mode

The new Dark Mode not only provides a modern, pleasant low-contrast display, but also automatically adapts to your smartphone's system mode – or can be activated manually at any time.
