South Australian John Altree-Williams has seen the summer quarter power costs for his Adelaide house plunge by 80 per cent from the previous summer after installing a Redflow-based energy storage system. As well as reducing electricity costs and improving energy independence by guaranteeing power supply during any grid blackouts, ZCell offers an Internet-enabled Battery Management System that allows Mr Altree-Williams to monitor closely his home’s energy usage patterns, enabling him to ensure it operates at peak efficiency so he can automate the system in future.
