Enphase Energy, Inc., a global energy technology company, today announced that it has made a USD$4.4 million investment to expand its global research and development (R&D) facility in Christchurch, New Zealand. Located in Wigram, Christchurch, the new R&D facility was officially opened today by the Hon. Steven Joyce MP, Minister of Science and Innovation. Gareth Hughes MP, Green Party of New Zealand and Dr Megan Woods for Wigram, were in attendance at the event. This new facility will allow Enphase to conduct global compliance testing and verification capabilities for its microinverters and expand on the future development of the Enphase AC Battery™, a modular energy storage system that integrates with the Enphase Home Energy Solution. The facility also has the capacity to allow for future expansion as the company assembles its second largest engineering workforce in the world outside of its lead engineering team in Petaluma, California.
