HV Battery Energy Storage Systems (BESS) Course

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.

🧠 What You’ll Learn
