Use all your potential.

STON is the storage system that enables even preexistent photovoltaic plants to store produced energy to use it when the Sun sets. You only need to install it to instantly start storing energy during the day and have it ready to use in the evening or night, when you need it the most.

STON uses LiFePO4 batteries with state of the art performance that need no maintenance with a guaranteed life cycle of more than 10 years

STON 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.

STON 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. Read more about ATON-CARE.
