Elements & performance criteria

Performance evidence

• representing the proposed system using labelled diagrams or digital simulations to show how the system works
• communicating information about the proposed system while participating in project activities with others, using appropriate energy sector terminology to explain how the system supports residential energy needs
• interpreting a project brief to identify the requirements and plan a basic ELV d.c. energy model that replicates residential battery storage functions to show how energy can be stored and transferred to meet basic energy needs during a simulated loss of power supply or limited grid access
