Electrical
A course by
WITT
A practical micro-credential for electricians and related professionals to design, install, and commission grid-connected battery storage systems integrated with photovoltaic (solar) power, focused on safety, industry standards, and system optimisation.
Blended study
This is a mix of online learning & face-to-face sessions
WITT Campus, New Plymouth
It will take a total of 3 weeks
Core skills this course teaches
Assess site suitability and calculate energy yield
Evaluate the appropriateness of a site for grid-connected battery storage and estimate potential energy yield for clients.
Analyse and optimise energy consumption
Assess a client’s consumption, create load/PV profiles, and provide options to improve self-consumption of PV energy.
Select appropriate battery technologies
Determine and recommend the best battery type for various scenarios based on technical and practical considerations.
What You're Signing Up For
This Level 4 micro-credential is designed for registered electrical workers who want to develop the skills and knowledge to design and install grid-connected battery storage systems, especially when combined with photovoltaic (PV) systems. The flexible course includes self-paced online modules, a three-day intensive on campus, and a post-course assignment. Topics span battery technologies, safety, system design, installation, regulatory compliance, and real-world application scenarios. The qualification is NZQA-registered and endorsed by SEANZ, the Sustainable Energy Association of New Zealand.
