missing data from SmartSolar MPPT RS 450/200

[dimitri-b1]

Hello,
I have a new system and just installed this plugin. It worked well and pulled bunch of data into 3 distinct devices - battery, system and vebus, which corresponds to unique IDs in Modbus TCP server on my Ekrano GX device.
However, I don't see much data from solar charger RS 450/200. I have the bare minimum DC PV Power in sensor.victron_system_dc_pv_power, but I was expecting other useful data such as yield and trackers, etc. which is exposed in VRM and GX screens.
Is it possible that scan is not picking up all available vebus registers from my solar controller?
BTW, this controller is connected to GX via VE.CAN
