Hi all,
Sorry if this is a dumb question.
In a typical solar installation we have a mains grid supply and a Solar Panel / inverter mains supply joined together. This combined mains supply supplies the house. If an excess of power is generated by the solar panel after supplying the house it is exported to the grid.
How does the house "know" to take it's supply from the inverter first and not the grid?
Dave.
