Will my solar system still work when the power goes out?

If the electricity / power goes out on a grid connected solar system the setup of nearly all inverters is to stop any delivery of power to loads throughout the house and grid. The purpose of this is for safety, if you can image that a linesman is fixing a fault on the High Voltage lines and has isolated power to the bloke and then a solar inverter was pushing power back through the system if would be a very deadly situation. Because of this inverters by regulation must disconnect from the grid. There are more specific inverters like Selectronics that are designed for storage capacity that can come with a changeover switch and allow power production but these are not the standard inverters in market and will require a most larger quantity of money to install.
