or is it possible to connect a ccs (combined charging system) to a home battery?

We have one solution to this: Assuming you have a Victron GX device and Victron Solar Charger: use a PLC to read the dbus register 784 "Yield kWh today" (you can also read and add "yesterday" and average if you wish and store this value as "derived storage yield". Then validate the battery (assume a CANbus connected battery that can be read into GX) charge at register 302. If sufficient charged capacity over a threshold you set, then turn on a Multi or Quatro and release the amount of energy to the vehicle as per the derived storage yield. It would be great if you could read the vehicle's energy deficit before charging to validate the residual charge left in your battery system. If insufficient then you could switch to grid feed and store the used energy as a deficit in the "derived storage yield" and watch this recover on a day you dont use the vehicle.
