My Roadster arrives in a couple of days. Already I am figuring about the charging. I have 18kWp Solar Power on the roof which is connected to the State Grid.
Now, as we do have periods of no power (at night or cloudy days), I use a "Current measuring Relay" in the PV system to switch a contactor which in turn will only connect to a bigger Load (e.g. the Tesla) when there is enough power from the solar panels.
This means, I do not want to charge the Roaster at night or when it is an overcast day. This system works perfect with a 9 kW hot water boiler.
So I wonder if it is possible to use it for the Roadster: to plug-in, slide the switch and let the relays do the job. Would the Tesla SW lock me out altogether if I slide the switch and if the power from the Contactor is dropped?
PS: Will Tesla do something for the 3-phase systems? Here in Europe almost every home has 240/400 V
