The energy of the Sun, at night.

Inside a simple and elegant design Ra.Store K hides its state of the art technology. Ra.Store K contains everything you need to install a new PV plant and reach even higher efficiency levels. Already set up for the new Smart Grids, Ra.Store K is the ideal Energy Manager for your house.

Ra.Store Kuses LiFePO4 batteries batteries with state of the art performance that need no maintenance with a guaranteed life cycle of more than 10 years

Ra.Store K can be configured so it can adapt to the photovoltaic plant’s needs to get the best performance with minimum stress.

The 2,5 kWh battery modules get checked one by one on our test benches in ATON facilities before we put them into our systems. This allows us to extend the standard warranty to 7 years (upgradeable). The system’s modularity is a core characteristic of our efficiency/effectiveness idea: having a smaller than optimal capacity doesn’t allow reaching the maximum possible saving because a lot of the energy made by the PV plant will be sold to the grid (at a low price), in the meantime an excessive capacity compared to the PV plant leads to efficiency problems in the long term (because batteries won’t be charged fully). Not to little, not too big: just right, that’s the way we do it.

Ra.Store K provides power to the house during power shortages.

Ra.Store K is constantly connected to the ATON Storage net to be monitored 24/7, it can communicate anomalies and malfunctioning so the technical team can intervene and restore full capabilities in no time.

PV energy provides mainly the home, the possible energy excess charges the batteries. Stored energy helps keeping everything online during low or no solar power and during high power uptakes. Discharges and withdrawals to and from the grid are kept to a minimum.


Stored energy is used in scheduled times (time shifting): in the other hours of the day the battery gets only recharged, even buying from the grid (optional) when the needs are low. This allows focusing the stored energy use on the highest needs hours and facing planned power shortages.


Some energy is stored in the battery – eventually buying from the grid (optional) – to use it when the system foresees high energy consumption or absorption compared to production (peak-shaving). It makes use of provisional models based on weather forecast, historical consumption data and machine learning.


In different scheduled hours the battery gets fully charged gathering from both PV and grid and then discharged (optional), selling to the grid or powering the house. Useful during a holiday trip or to exploit energy cost differences between time frames.


In the event of a grid malfunction, the utilities are powered by quickly activating the Off-Grid output.
