Solar Energy - Grid-Connected Battery Storage Systems: Design & Installation


Grid-Connected Battery Storage Systems, particularly those integrated with Grid-Connected Photovoltaic Systems, provide many valuable options to home and business owners. However it is essential that electrical workers involved with these systems fully understand the operatingtheory and safety requirements in order to design and install safe and effective systems, as well as adequately manage customer expectations.

Course Structure

The delivery of this course is designed for busy tradespeople who do not have the time to attend lengthy face-to-face courses.  The online component is fully flexible to allow students to complete the theory in their own time.

  • Pre-course learning:  Online self-directed learning at your own pace, with tutor support (100 hours)
  • Three day course at WITT/Infrastructure Park (24 hrs)
  • Post-course assignment (16 hrs)

This is a recommended pre-requisite course for those wanting to install complete standalone (off-grid) systems and builds upon the basic knowledge provided in Grid-Connected Photovoltaic Systems.
