Course Overview
The HV Battery Energy Storage Systems (BESS) course is designed for qualified electricians, solar installers, and contractors who want to move beyond residential work and confidently enter the Commercial & Industrial (C&I) solar sector.
This programme provides practical, real-world insight into the design, sizing, safety, and commissioning of high-voltage battery storage systems — where precision, compliance, and risk management are critical.
Unlike conventional solar design courses, this masterclass goes far beyond theory. It focuses on what really happens on-site, from feasibility studies to commissioning, fault-finding, and financial performance evaluation.

Avoiding common financial pitfalls in energy storage
This course is led by Carel Ballack, one of South Africa’s leading solar energy experts and compliance specialists.
With decades of hands-on experience in PV auditing, energy performance, and system safety, Carel has a rare ability to simplify complex HV systems through real project examples. Participants will gain a deep, practical understanding of how to succeed in commercial HV installations.
📸 Case Studies & Real Installations

I struggled at first with the order because it kept asking me for the address, even when it was an online purchase. I put my address in, but for some reason it kept returning an error message. At long last, the order went through and I received the SANS 10142 book as ordered. Thank you to TDMI Training.
Thanks TDMI for the new digital SANS 10142-1 edition 3.03. It was quickly received and installed on my phone. It is now quick and easy to find the correct regulation I need on a site or anywhere at any time I need to.
The online video sessions are very helpful, not rushed and things are explained thoroughly. I love the fact that there are quizzes at the end of each video as that helps me test if I understood the content and if I missed anything, I could go back to the video again.
The Student Portal is very easy to navigate and very user-friendly.
I am finding it great learning all the regulations on Paper 1 haven't started with Paper 2 yet. All the material I received I am pretty sure will assist me to get me prepared for the upcoming exams.
I can genuinely say this course has been one of the best investments I’ve made in my career.
What I love most is that I don’t have to rely on memory alone. Instead of trying to absorb everything in a one-week class, I have lifetime access to the lessons. I can go back, rewatch the videos, and learn at my own pace whenever I need a refresher.
The practical demonstrations are what make this course so valuable. Seeing exactly how the testing, inspections, and COC process are done has given me so much confidence.
Thank you for creating something that doesn’t just teach us to pass a course,it equips us to become better electricians. I highly recommend it!
