Schneider Electric and NGK Insulators have reached the conclusion of a memorandum of understanding (MOU) under which both companies will explore global opportunities to jointly market NGK's NAS (R) battery and Schneider Electric's inverter (Conext Core XC ES).

Back in November 2016, both Schneider Electric and NGK successfully completed integration testing of the system between the NAS battery and ES Box at NGK's factory in Komaki City, Aichi Prefecture, Japan.

Integrating Schneider's energy management technology with NGK’s battery storage technology makes it possible to store large amounts of electricity with a smaller footprint. The battery uses a sodium-sulfur (NaS) chemistry and has been commercially available since 2002, used in 530MW of deployed projects at grid-scale globally. 

The Conext Core XC ES is a series of central inverters designed for high efficiency and flexibility for battery-based energy storage systems — with the series boasting a peak efficiency of 99.1%. NGK commercialised the NAS battery system, which is capable of storing MWs of electricity.
