HEIWIT sodium ion storage for three residential installations in Veneto

Jan 30, 2026 | Gallery installations

Three residential projects in Veneto with storage systems HEIWIT to sodium ions, made by ARCA 360 SRL between the provinces of Vicenza and Padua.

Work on private homes between Vicenza and Padua

The installations were realised in the context of private homes in Veneto, in Creazzo (VI), Rubano (PD) and Altavilla Vicentina (VI).

Overall, three separate interventions were carried out:

  • two installations on existing photovoltaic systems but initially without a storage system
  • a complete replacement of an existing, non-range storage system HEIWIT

The interventions made it possible to integrate or renew the storage function in existing systems, improving the management of energy produced in the household.

Installation by ARCA 360 SRL

The realisation of the three interventions was carried out by ARCA 360 SRL, a company active in the field of renewable energy installations in the residential sector.

During installations, ARCA 360 SRL was able to deal directly with the service HEIWIT, and found good availability and effective support in the operational phases.

Installation experience and first evaluations

From an operational point of view, the overall experience was positive.
Installations were regularly completed both in cases of integration on existing systems and in the complete replacement of the existing storage system.

Residential storage and energy management

The project involving the three homes between the provinces of Vicenza and Padua represents a concrete example of the application of HEIWIT sodium ion storage systems in the residential sector.

Interventions of this kind demonstrate how it is possible to integrate storage on already operational photovoltaic systems or to replace previous systems, contributing to a more efficient management of the energy produced.
