Lunar Energy has announced the launch of a 25kW DC fast home charger, designed to work in tandem with the company's next-generation home battery system. The new charger does not only charge electric vehicles at faster rates, but also allows compatible vehicles to support home operations during power outages and potentially generate profit by redirecting excess electricity to the public power grid.
According to the timeline announced by the company, the updated home battery system is scheduled to be rolled out to customers in early 2027, while the fast home charger is expected to launch in the middle of the same year. The technical design shows that the charger connects directly to the DC side of the Lunar battery, a design the company asserts avoids the need for costly home electrical panel upgrades. The charger also supports CCS and NACS connectors, with the caveat that users must verify their vehicle's compatibility with bidirectional charging features.
What does the new system offer in practice?
The fast home charger can add a driving range of approximately 100 miles per hour when operating at its full 25kW capacity, with actual results varying based on vehicle type and charging conditions. With a compatible vehicle, Vehicle-to-Home (V2H) technology can extend the backup power duration throughout an outage for several days, depending on the vehicle's battery capacity and the home's consumption level. Similarly, payments resulting from Vehicle-to-Grid (V2G) charging are tied to the availability of local and utility-provided programs.
Home battery specifications and commercial sector expansions
The updated system comes with a 13.4kW power inverter and relies on 5kWh battery modules. A single tower provides capacities ranging from 10 to 30kWh, while towers installed side-by-side can provide up to 300kWh of energy. Furthermore, the company has expanded to serve the small commercial sector with configurations reaching up to 1MWh to reduce peak demand charges. It is worth noting that the system supports both new and existing solar energy systems or can operate entirely without solar panels, with assembly operations carried out in California, Georgia, and Washington.
Smart energy and price management
The company's software ecosystem relies on smart algorithms that process electricity prices, weather forecasts, and consumption rates to determine the optimal timing for charging batteries or discharging energy. The company indicates that its customers in California achieved an average additional saving of $338 last year thanks to the use of the smart operating mode compared to traditional systems. Conversely, the company has not yet released official pricing details or a list of vehicle models compatible with bidirectional charging features, which are essential details awaiting announcement.
