High voltage issues are often ignored or simply not even considered. However, if not managed properly, it can become an annoying problem for your household. In Australia, the normal grid voltage is between 225 and 240 Volts (V). Voltage levels will fluctuate during the day depending on how much power is being drawn from the grid, and how much solar is being sent back. It is up to the electricity distributor to monitor the voltage levels; however, it is becoming more difficult to keep voltage levels below 254V.
