We are excited to announce that HEIWIT will attend Key - The Energy Transition Expo, the European event dedicated to energy transition, sustainable technologies and future energy solutions, scheduled to take place from 4 to 6 March 2026 at the Rimini Expo Centre.

Key is one of the leading B2B events in Europe for the energy sector: a unique opportunity for operators, installers, designers and companies interested in storage technology, energy efficiency, electric mobility and renewable energy.

HEIWIT sodium ion batteries: technology on show

During the fair you can see HEIWIT sodium ion batteries in single-phase version live, already available on the market and subject of the first installations carried out in recent months.
This technology represents a concrete and innovative alternative to traditional lithium batteries, with advantages in terms of durability, operational safety and environmental sustainability.

HEIWIT sodium ion batteries fit perfectly into storage systems for photovoltaic systems and hybrid solutions, contributing to greater energy independence and supporting the spread of renewables through solutions scalable and performant.

New: the three-phase battery for industrial applications

At the fair you can also discover the new HEIWIT three-phase battery, developed to respond to the industrial application needs.
This new product expands the HEIWIT range, offering a solution designed for higher power environments, where it is essential to ensure stability, efficiency and continuity of power supply.

Participating in Key will allow you to:

• get to know the Technical characteristics of HEIWIT sodium ion batteries, with a focus on reliability, sustainability and integration with photovoltaic systems;

• explore the functioning and benefits of the single-phase batteries already installed on real systems;

• discover the potential of the new three-phase battery for industrial applications;

• meet the HEIWIT team, ready to answer your questions and discuss the different applications of our solutions.
