Local electronic printed circuit board (PCB) manufacturer Bosco is using a flow battery energy storage system alongside a rooftop solar energy and a battery management system (BMS) to keep a crucial production line and its engineering and sales departments free of disruptions caused by power outages that are common in South Africa. The main competitive advantage the company has over duty-free imported PCBs is its ability to serve its local clients quickly and accurately, which means it must prevent disruptions to its ability to engage with its clients, provide quotes and ensure its engineering and design department continues to operate, explains Bosco Director Philip Verheul.
