The companies have been collaborating on electric mobility and home storage since 2013.
With the launch of the first models in the Neue Klasse, the BMW iX3 and the BMW i3, BMW says it is beginning the rollout of its bidirectional charging technology.
Following Germany’s first commercial Vehicle-to-Grid (V2G) offering – available since March 2026 – the next logical step for Vehicle-to-Home (V2H) is now being taken: BMW iX3 and BMW i3 customers can now make even more extensive use of this new technology in their vehicles.
BMW points out that with the increasing electrification of mobility and customer households, new opportunities are emerging for holistic energy optimisation and the integration of both ecosystems.
As part of this, BMW and SOLARWATT are optimising the integration of the electric vehicle into the customer’s household. To this end, the SOLARWATT Manager home energy management system (HEMS) will serve as the link between both ecosystems in the future.
The SOLARWATT HEMS handles the central and intelligent control and optimisation of energy flows in the household via coordinated and communicating components. This, the companies say, efficiently optimizes the generation, storage, and consumption of energy.
The electric vehicle is seamlessly integrated into the interaction between the photovoltaic system (PV system), home storage, and consumers in the home as an additional storage unit.
This home network integration is made possible by combining BMW Neue Klasse models with the bidirectional BMW Wallbox Professional, which not only charges the vehicle but can also feed energy back into the home when needed.
The market launch for the integration of bidirectional BMW vehicles into SOLARWATT’s new HEMS for Vehicle-to-Home (V2H) applications is planned for late 2026 in Germany, Austria and the Netherlands.
BMW and SOLARWATT launched a home storage system featuring a battery module in 2021 that incorporates components also used in the BMW Group’s electric vehicles. Since 2025, the successor model, SOLARWATT Battery vision, has been available, with its housing and design created by BMW Designworks USA.
“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. For many homeowners, the prospect of expanding an existing home battery storage system with an electric car is highly attractive. This significantly increases the benefits of one’s own PV system, lowers electricity costs, and makes the home even less dependent on purchasing electricity from the grid,” says SOLARWATT CPO Peter Bachmann.
“At the same time, bidirectional charging holds enormous potential for the energy transition, as the batteries of electric vehicles collectively form a massive storage reserve. If this flexibility is intelligently integrated into energy markets and households, it can help relieve the strain on power grids, better integrate renewable energy, and make additional storage capacity available quickly and cost-effectively,” says Marcus Krieg, Vice President New Business at the BMW Group.
