Hello friends,
I wanted to ask if anyone can help me with this application.
I have voltaic panels and I would like to inject the surplus energy (when there is some) into an electric water heater.
So the power to the water heater from the electrical network will drop.
I don't know how to call this device in English.
Does it exist ready made or DIY (triac, ...)?
It would also be necessary not to send parasites, polluting frequencies towards the network of the distributor.
Thank you.

You cannot mix grid supply and your solar supply willie nillie.
It must be an approved grid tie system which automatically drops out when the grid goes down.
Reason being, without this, your system could backfeed the grid and create a fatal situation for line workers etc.

Other than that I have misunderstood your query.

Not sure but I think you are referring to a solar water heater controller or solar diversion controller.
