Panasonic Electric Works, a unit of Japanese electronics giant Panasonic, has developed a vehicle-to-home system (V2H) that facilitates two-way flows between solar-powered homes and electric vehicles.
The company said it will start selling its Eneplat system in Japan from February.
“In addition, from next summer we will also sell an upgraded version of our AiSEG2 management system that links various home appliances and equipment with Eneplat,” it said.
The company said its new V2H system is the first in the industry to handle the simultaneous charging and discharging of electric vehicles and batteries. The AiSEG2 system can reportedly forecast surplus power based on daily power consumption and automatically control the charging and discharging of batteries..
It has a rated output of 6 kW and can be charged with a maximum PV power output of 9 kW. The standard lithium-ion battery has a storage capacity of 6.7 kWh.
“The V2H system has a compact size and can be installed on a floor space smaller than that of one air conditioner outdoor unit,” Panasonic explained, adding it measures 1,250 mm x 420 mm x 210 mm and weighs 60 kg. “It is easy to install, even in a limited space in a parking lot.”
It said the system can increase the self-consumption rate of homes with rooftop PV and storage from about 50% to approximately 90%. It will sell for JPY 1.76 million ($13,075).
The company also said that in February, it will reveal which electric car models will be compatible with the new V2G system.

$13,000 seems very expensive for a device that simply allows a car battery to charge & discharge from a home’s solar panels.
“..the system can increase the self-consumption rate of homes with rooftop PV and storage from about 50% to approximately 90%” — so not as if your home’s self-consumption would go from 0 to 90%, but only increase from 50 to 90%.
For that price ($13k), you could get a big (15kWh+) Dedicated battery system, that wouldn’t get driven off periodically..for hours or even days at a time!
Besides that you are reducing the life of your car battery. Which is probably more expensive e
