Fronius Energy Cost Assistant

AI-based energy management

Optimized energy flows, maximum savings

The Fronius Energy Cost Assistant automatically supports you as a PV system owner with battery storage to improve your energy use. This allows you to get the most out of your storage system and also save on electricity costs.

Thanks to advanced AI technology, the energy cost assistant continuously analyzes the expected PV production of your system, your energy consumption and the current electricity price and adapts the storage strategy accordingly. Your benefit: not only does your electricity bill drop significantly, you also make optimum use of your energy resources without any additional hardware, simply in the app.

What are variable tariffs?
Variable electricity tariffs are price models in which electricity prices fluctuate depending on consumption or market conditions. In contrast to fixed-price tariffs, they can be both cheaper and more expensive. However, they offer a high degree of flexibility in energy use and can therefore be used optimally with an intelligent system.

Using variable tariffs economically  

Even variable electricity tariffs become your advantage with the Fronius Energy Cost Assistant: it reacts reliably to fluctuations in energy prices and thus always determines the ideal time to charge or discharge your battery.

Energy prices are retrieved directly from the exchange and integrated into the AI-supported energy optimization. If the electricity price is low at night, for example, your battery is automatically charged via the power grid. This allows you to benefit from low electricity prices, even when the sun isn't shining.  

The assistant also limits the discharge of your battery when the electricity price is very low. This leaves enough energy in the battery that you can easily access later when the electricity price rises. In this way, high consumption peaks are absorbed and expensive electricity tariffs are avoided

As the degradation of the battery is taken into account, the service life of the storage system is not jeopardized

Everything in one app

You can easily activate the Energy Cost Assistant via the Fronius Solar.web web view and make all the settings. Our app not only provides you with up-to-date information about the consumption and yield of your system, but also whether the Energy Cost Assistant is currently active. If required, the Energy Cost Assistant can be deactivated at any time.

Activate the Energy Cost Assistant with your Fronius Solar.web Premium account and save money.
