Residential Energy Storage Systems

Store off-peak energy in storage system, Use excess solar power to capture maximum benefits at home

Solution promise and positioning

With the rapid growth of renewable energy, such as photovoltaic generation, the use of energy storage systems is expected to spread greatly and meet with increasing social needs.
Such systems will allow households to efficiently reduce electricity costs, by leveraging off-peak, e.g. night-time, power and storing excess solar power during daytime. Moreover, this stored power can be leveraged also during emergencies such as blackouts.
NEC provides "Residential Energy Storage Systems" to meet residential customers’ power needs. NEC has acquired in automotive-grade quality, reliability and mass production to provide best-in-class customer experience.
These "Residential Energy Systems" being designed and manufactured only for the Japanese market.
They are sold only in Japan.
