Neue Klasse vehicles are becoming a central component of the home energy ecosystem: BMW and SOLARWATT are expanding their partnership.

Munich/Dresden. BMW and SOLARWATT are further expanding their collaboration in the field of smart energy and home charging solutions.

With the launch of the first models in the Neue Klasse, the BMW iX3 and the BMW i3, BMW 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.

With the increasing electrification of mobility and customer households, new opportunities are emerging for holistic energy optimization and the integration of both ecosystems.

As part of this, BMW and SOLARWATT are optimizing 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 optimization of energy flows in the household via coordinated and communicating components. This 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 have been collaborating in the field of electromobility since 2013. In 2021, the two partners also launched a home storage system featuring a battery module 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.

Smart Connectivity: Energy Management and Home Network Integration in perfect harmony

Since the launch of the Neue Klasse, BMW has relied on Vehicle-to-Home (V2H) technology as a gateway to bidirectional charging, the use of solar energy, and the reduction of energy costs.

The offering is now being expanded to include home network integration for optimal energy management. This marks a significant advancement for V2H applications. The intelligent interaction of all components (BMW electric vehicle, BMW Wallbox Professional, HEMS from SOLARWATT, home storage, and other consumers) creates a holistic system that not only optimizes self-consumption but also takes the flexibility and efficiency of the home energy supply to a new level.

Homeowners control their settings via the My BMW App and the SOLARWATT Home app. With the V2H option, the electric car serves as additional storage for surplus solar power generated by the PV system. In addition to optimizing the interaction of all components, the SOLARWATT Manager allows for the integration of dynamic electricity rates and the incorporation of solar forecasts to further optimize charging and discharging processes, further reduce energy costs, and increase self-sufficiency.

The SOLARWATT Manager is designed to be open: In addition to SOLARWATT's product range, home storage systems from other brands can also be integrated. This creates a flexible home energy system that can be expanded in stages.

Overall Optimization: Electric Car Complements Home Battery Storage

“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.

Market Launch and Future Strategic Direction

Following the next public milestone at Intersolar (The Smarter E), the focus is on the phased implementation of the next project milestones leading up to the market launch at the end of this year.

BMW and SOLARWATT consistently place the customer and their entire ecosystem at the center of their efforts. The partners aim to enable seamless and reliable interaction between all components in the home and in the vehicle. In doing so, they create a consistent, integrated customer experience and strengthen their position as leading companies in the field of connected vehicle and home usage.
