In this explanation of @mvader (Victron Energy Staff) in this youtube https://www.youtube.com/watch?v=tbpQzEZTElI is shown dat a solarpowered multiplus with batteries can also deliver back to the grid without any extra pv inverter.
My Victron situation is exactly the same. What do i have to setup within the Multiplus to deliver acpower back to the grid. And can this be done through the same 230V ac input cable i use for charging my batteries through the Multiplus when there is not enough solarpower.
