I have an existing simple ESS system currently using a single Multiplus II GX, mains connected on the input only, using the simple wired CT plugged directly into the Multi. It's working fine.
I want to expand the system using a second parallel slave Multi II (non GX) with VE.Bus.
Question is, does the slave require its own CT plugged in?
When I tried it without a second CT, VRM Remote Console reported export to grid at the same rate as the AC load even though grid setpoint was set at zero..
I will need to order a second CT if needed, hence the question.
Thanks, Guy
