Electrical
A course by
WITT
This course equips electrical professionals with the knowledge to design, assess, and commission stand-alone power systems for off-grid and remote applications. Delivered through flexible online study and a practical on-campus component.
Blended study
This is a mix of online learning & face-to-face sessions
WITT Campus, New Plymouth
Core skills this course teaches
Assess site suitability and calculate energy yields
Participants will be able to assess whether a site is suitable for a stand-alone power system and calculate monthly estimated energy yields for clients.
Evaluate and profile client energy consumption
Graduates will be able to assess a client's energy use, create load versus renewable energy profiles, and estimate the proportion of renewable and generator-supplied energy.

What You're Signing Up For
Stand-alone Power Systems: Design only is intended for electrical engineers and technically trained professionals looking to gain advanced knowledge of designing, assessing, and optimising off-grid renewable energy systems. The course covers site and load assessment, battery technology, renewable resource integration, system design and safety, relevant standards, and commissioning processes. It builds upon knowledge from grid-connected PV and battery system design and is endorsed by SEANZ. The program is delivered with a blend of self-paced online study and a three-day in-person component.
