KOSTAL Solar App

Using the KOSTAL Solar App, customers can also monitor their systems easily via their smartphone or tablet – free of charge, of course.

With the KOSTAL Solar App, you can conveniently monitor your solar systems either on the move or from your home sofa and display relevant system data. You have the option of obtaining consumption and generation data over various periods such as day, week, month and year, as well as access to the historical data of your system so that you are always up to date.
The holistic PV monitoring of the KOSTAL Solar App also includes, for example, how much energy is stored in the battery and how the own consumption is made up of PV and battery.

Even if you do not have a battery yet, you can calculate an individual forecast thanks to the virtual battery. In addition, the app gives you an overview of how many kilometres you could drive with an electric vehicle or how long you could shower with your own generated energy using a heat pump.
The free KOSTAL Solar App offers you professional monitoring of your photovoltaic system at any time simply and conveniently via smartphone or tablet.

To set up and use the app, you need access to the KOSTAL Solar Portal and an inverter set up there. The same access data as for the solar portal is required for logging in to the app.

The KOSTAL Solar App is available for the Android and iOS operating systems.
