Lunar Unveils Home DC Charging for Electric Vehicles with Backup Power
Lunar has unveiled a 25 kW home DC charger: a compatible electric vehicle will be able to power a home during a grid outage. The battery will launch in early 2027, and the charger in mid-2027.
The device connects directly to the Lunar System battery and, according to the company, does not require an electrical panel upgrade. The charger supports CCS and NACS connectors, though Lunar has not yet specified which electric vehicle models are compatible with bidirectional energy transfer.
Charging a vehicle and sending power back to the home are separate functions. With V2H (vehicle-to-home) support, an electric vehicle will be able to extend the operation of home systems during prolonged power outages. The actual duration of backup power will depend on the vehicle's charge level and the appliances connected.
Through V2G (vehicle-to-grid), the owner may also receive payments for supplying energy back to the grid when demand rises. However, such payments depend on the availability of relevant programs and are not an automatic result of installing the charger.
The updated Lunar System features a 13.4 kW inverter. The modular battery can be scaled: multiple towers in a single home provide up to 300 kWh of storage. The system works with new or existing solar generation and can also be used without solar panels.
Lunar AI manages the timing of charging and energy discharge: the program considers tariffs, weather forecasts, and household energy consumption habits. Adding an electric vehicle allows coordination of its battery with the home storage system and solar panels. The company also offers the option to combine storage systems into virtual power plants managed by energy providers.
