Nissan is the latest automaker to enter the market for in-home power storage.
The Japanese automaker earlier this month announced a deal with industrial giant Eaton to develop what they say will be the most affordable energy storage unit on the market.
The xStorage system, like other home energy storage units, could store intermittent renewable power sources — particularly solar — for future use.
It could also enable homeowners to curb their power use during expensive daytime hours, maintain power during outages or sell unused energy back to the grid.
Nissan and Eaton also said that xStorage would be the first fully integrated storage system for homeowners; essentially, once installed by a professional, the unit would give consumers "the ability to plug in and power up easily."
The system will also include Internet connectivity to ensure that homeowners can switch between power sources using a smartphone.
"We want to make energy storage exciting and affordable to everyone, not least because it delivers real consumer benefits whilst ensuring smarter and more sustainable energy management for the grid," Nissan Europe Chairman Paul Willcox said in a statement.
xStorage is powered by 12 Nissan battery modules recovered following their initial use in the company's electric vehicles.
Nissan is one of a handful of companies to apply their automotive battery advancements to power storage, including Mercedes-Benz owner Daimler and electric car pioneer Tesla.
The companies — which are focused on the European market and have no plans to sell the system in the U.S. — expect to sell more than 100,000 units within five years. Pre-orders are slated to begin in September at a starting price of 4,000 euros for 4.2 kilowatt-hours of power capacity.
