What Happened

BMW and SOLARWATT are strengthening their partnership to deliver holistically optimized home energy solutions. With the launch of the Neue Klasse models iX3 and i3, BMW introduces bidirectional charging technology. The integration with SOLARWATT’s Home Energy Management System (HEMS) allows the electric vehicle to serve as additional storage for solar power, feeding energy back to the home when needed. The market launch is planned for late 2026 in Germany, Austria, and the Netherlands.

“Drivers of a Neue Klasse electric car like the BMW iX3 can use the additional storage to make even more efficient use of self-generated solar power, increase self-consumption, and thus reduce their reliance on expensive grid electricity.”
— Peter Bachmann, CPO, SOLARWATT
“Bidirectional charging holds enormous potential for the energy transition, as the batteries of electric vehicles collectively form a massive storage reserve.”
— Marcus Krieg, Vice President New Business, BMW Group

Why this matters

This partnership enables homeowners to use their electric car as a battery for solar power, reducing electricity costs and supporting the energy transition by making renewable energy more accessible.
