What happens when the Grid Power fails?
In the event of a Grid Power Failure, the inverter will automatically turn off to ensure that electricity is not being fed into an unsafe situation (e.g. power lines down). This is called anti-islanding protection and is a requirement of the Australian Standard AS4777 to ensure the safety of the network to which the inverter is connected.In order to maintain electricity supply during a blackout, you would require a system with an integrated UPS (Uninterrupted Power Supply). The equipment required to do that job is quite costly and out of reach of most people. If you only need to maintain supply to a small appliance such as a computer during a blackout, a more cost effective solution is to purchase a separate standalone UPS system for that appliance.
