Nissan said the storage units, which are available to pre-order from September, are designed to be the most affordable in the market at £3,200 for the full installation of a 4.2KWh unit.
It said it expects to sell more than 100,000 xStorage units within the next five years as consumer appetite for this type of technology grows.
The launch also marks the start of a longer-term commitment by Nissan and Eaton to widen the portfolio of energy storage solutions available to both private and commercial customers.
The fully integrated devices also give a second life to electric vehicle (EV) batteries, with each unit consisting of twelve Nissan EV battery modules.
Domestic energy storage will allow consumers to take advantage of time of use tariffs which will be introduced following the rollout of smart meters alter this year, cutting their energy bills in the process.
Consumers utilising these tariffs can charge their unit when demand, and therefore prices, are low and avoid using energy during peak periods, or use the power from an installed solar PV system. The xStorage system can also be controlled via a smartphone.
Nissan Europe chairman Paul Willcox said: “The new xStorage solution combines Nissan’s expertise in vehicle design and reliable battery technology with Eaton’s leadership in power quality and electronics, resulting in a formidable second life battery solution.
“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.”
Eaton Electrical EMEA’s vice president marketing Cyrille Brisson said: “The collaborative development between Eaton and Nissan enabled us to optimize development and production costs and deliver a well-integrated offer to consumers.
“Our policy is to avoid hidden extra costs and achieve a lower total cost of ownership than other major offers already announced.”
