I have a pair of Sunny Boy 5000 PV inverters without Speedwire/Webconnect modules. Is it possible to connect their output via a 100A/50mA CT to my Cerbo GX or Multiplus II? I have read that I need the Speedwire module, but don't believe this as all I want is a CT's signal named PV or whatever that's read by my Victron equipment.
