The need to be able to accumulate the energy of the sun, to use it in periods of low or strictly light at night, is increasing exponentially and people are constantly looking for their own energy independence.

For this reason, Western CO., leader in the sector of off-grid systems, has designed, produced and placed on the market a line of storage systems suitable for the residential market.

With the Leonardo PRO and Leonardo 4K systems, the user can add an accumulation system to an already built system connected to the distribution grid, or he can build a new photovoltaic system with battery storage.

Thanks to the combinations with the best brands of lithium batteries, the performance and useful life of these systems have increased significantly.



Existing PV systems

To improve the performance of your system

Do you have a photovoltaic system with incentives and close to expiration? Do you want to continue to get benefits from your PV system even when the incentives end? The ideal solution is our Leonardo PRO.

The Leonardo PRO is a grid-connected storage system specifically designed to be installed in existing on-grid photovoltaic systems in order to increase the share of energy self-consumed by the user and thus maximize energy independence.
It is compatible with any PV system, including those with government incentives (such as the “II-V energy bill” decrees) without altering the amount of energy produced and incentivized. In the event of a power failure, the Leonardo PRO is able to completely power the house until the battery is completely discharged.

È inoltre possibile monitorare il vostro sistema in qualsiasi momento tramite app o web.

New PV systems

For a system with very high performance

Have you decided to build a PV system and want to store the energy produced during the day to be able to use it when you mostly need it? You don’t know which one to choose between the many storage system manufacturers? The solution for you is the Leonardo 4K.

This storage system is entirely designed and manufactured in Italy. The security of having a national manufacturer that has been on the market for over 30 years is a guarantee with respect to the coming and going of new and questionable storage systems. The Leonardo 4K is certified with the best lithium battery brands on the market today. Furthermore, you can monitor your system at any time via app or web.

The Leonardo 4K is a management and control system for a storage and solar photovoltaic production system. It is able to reduce the withdrawal from the network meter, to guarantee the complete self-consumption of the energy generated and to maximize the energy independence of the domestic user. Since the Leonardo 4K does not feed energy into the grid, there is a significant simplification and reduction of bureaucratic practices related to the installation.
