Lunar Energy has unveiled a 25-kilowatt home DC fast charger that will do more than just power up a car quickly, Electrek reported.
Paired with its next-generation home battery system, the Lunar Fast Charger will also let a compatible EV help keep the house running during an outage and potentially earn money by sending electricity back to the grid. The new battery system will be available to customers in early 2027, with the charger rollout expected in mid-2027.
Lunar says its home DC fast charger can add roughly 100 miles of range in an hour at up to 25 kW. Actual results will depend on the vehicle and charging conditions. This is a DC charger, according to Lunar's product specifications. It connects directly to the DC side of the Lunar Battery, and Lunar says that setup avoids an electrical panel upgrade for the charger. The product page lists CCS and NACS connector support but does not specify which cars will support bidirectional charging. That distinction matters. Charging an EV and sending power back are separate capabilities, so buyers will need to check vehicle compatibility before relying on home backup, Electrek noted.
Backup power, grid payments, and where it is made
With a compatible EV, Lunar says vehicle-to-home charging could extend backup power through a multi-day outage. How long it lasts will depend on the car's available battery capacity and what is running in the house. Vehicle-to-grid payments will also depend on the availability of programs. They are not an automatic benefit of installing the charger.
The updated Lunar System has a 13.4 kW inverter and uses 5 kWh battery modules. A single tower holds 10 to 30 kWh, while towers installed side by side can provide up to 300 kWh. Lunar is also expanding into small businesses, with pad-mounted configurations reaching 1 MWh. Businesses could use the batteries for backup and to reduce demand charges, or fees tied to their highest power draw. The system can work with new solar using Lunar Maximizer panel optimizers, existing solar, or no solar at all. Lunar says assembly takes place in California, Georgia, Idaho and Washington, with engineering and research and development in Mountain View, California, Electrek reported. The dates to mark are early 2027 for the new battery and mid-2027 for the 25 kW charger. Until those products ship, the announcement is a specification and a timetable, not a charger already on a garage wall.
