I have a grid-connected solar inverter. In the swtich board the incoming wire from the street, the incoming wire from the inverter and the outgoing wire to the loads in my house are all connected together (wired in parallel).
It appears that the loads in the house will consume all available solar power (if needed) before drawing power from the grid.
How does this work? Why doesn't the load draw power equally from the solar inverter and from the grid?
I suspect that the inverter monitors the grid voltage and produces an output voltage that is just a few volts higher. Is that all that is needed for the loads in the house to use all the solar power before using grid power?
