Smart storage
Our intelligent software manages your battery automatically by making the most of your solar production and charging when it is cheapest, whether from your solar panels or from the grid. By using price and production forecasts to make optimal decisions, the software will even sell energy back to the grid when financially beneficial. All of this happens in the background, with no manual input required.
The savings shown are based on a 10 kW / 20 kWh home battery, an annual consumption of 6,000 kWh and an annual solar injection of 6,000 kWh. All savings are compared to a situation without a battery. Calculations are based on a grid offtake rate of €0.19/kWh and an injection rate of €0.04/kWh. The saving for Smart Storage vs. Self-consumption + Dynamic reflects actual results from our smart services in 2025. The saving for Self-consumption + Dynamic vs. Self-consumption + base rate is based on a comparison between the base fixed market rate as of 15 May 2026 and the realised dynamic price over 2025. Shown savings are indicative and no rights can be derived from these calculations.

Smart Storage is a service within Frank's home energy optimisation software. All your energy assets now work together as one:
This allows you to prioritise self-consumption wherever possible and minimise the energy you draw from the grid, reducing taxes and surcharges on your bill.

The software continuously determines the best energy source at any given moment. This means you use your solar production when it is most beneficial, charge from the grid only when it is cheapest, and avoid consuming power during expensive periods. The result is a more efficient use of power and real cost savings.
We continue to develop new features, such as automatic power trading to sell power back to the grid when it is financially beneficial. We keep evolving so your electricity always works in your favour.
