This course provides electrical workers, engineers, and technical salespeople with the practical knowledge to design safe and effective grid-connected battery storage systems. It covers operating theory, safety requirements, system components, regulations, and optimisation for renewable energy self-consumption. The structure combines online self-paced modules, a three-day intensive at WITT New Plymouth campus, and a post-course assignment. Participants will learn site and load assessment, battery technologies, system design with relevant standards, and best practice commissioning and optimisation. SEANZ endorsement affirms alignment with industry needs. A certificate of completion is awarded (non-NZQA).
