Currently Tesla estimates the Powerwall 2 battery plus supporting hardware will cost $8750 in Australia, not including installation costs. This doesn't include a solar PV array. Prices may vary between suppliers. The battery is smartly styled and designed for easy connection into the home power system.
âGroundingâ a tool or electrical system means intentionally creating a low-resistance path that connects to the earth. This prevents the buildup of voltages that could cause an electrical accident. Grounding is normally a secondary protective measure to protect against electric shock. It will substantially reduce the
Regulations for earthing system vary considerably among countries and among different parts of electric systems. Most low voltage systems connect one supply conductor to the earth (ground). protective earth (PE), known as an equipment grounding conductor in the US National Electrical Code, avoids this hazard by keeping the exposed conductive surfaces of a device at earth potential. To avoid possible voltage drop no current is allowed to flow in this conductor under normal circumstances.
