In addition to charging electric vehicles from homes, it is also possible to supply power from electric vehicles to homes. Domestic electric vehicles can be used as storage batteries!

Our company sells the "EV Power Station," which allows the electricity stored in electric vehicles (EVs) to be used as household power, and we provide information on the V2H system. By charging the EV at night when electricity rates are low and discharging it during the day when rates are high, it is possible to reduce electricity costs. Additionally, by effectively utilizing solar power, we can achieve a lifestyle that minimizes risks and allows for long-term peace of mind. Our company has experience in installing solar power systems for both single-family homes and large-scale projects, and we take responsibility for maintenance as well. If you have any questions regarding proposals or information for homeowners, including pricing and estimates, please feel free to contact us. 【Features】 ■ Reduces electricity costs through peak cutting ■ Incentive BCP through peak shifting ■ Social contribution through the utilization of electric vehicles ■ Emergency power outage measures (BCP) ■ Compatible with VPP (Virtual Power Plant) *For more details, please refer to the related links or feel free to contact us.
