My Victron system is grown over three years, starting with some flying solateur and added compounds in three stages. It looks a bit like that 
.
1st Stage:
4.4 kWp AC roof 10° Northeast
Sofar Solar 5.5 KTL-X inverter
Multiplus II
Pylontech 2000C starting with one grown to four (9.6 kWh)
Cerbo GX
ET340
2nd Stage:
2,4 kWp facade (60°) southwest
5.6 kWp roof roof 10° Northeast
Kostal 8.3 DCS
3rd Stage:
2x0.96 kWp roof and fascade south east 90°
Smart solar 150/45 MPPT
Victron is running as ESS with node red.
The visualization is via Solaranzeige
The Inverter data are send to Venus OS via MQTT
An additional script made the ET340 giving reasonable data in the VRM portal.
My home visualization is running on an outdated tablett with Kiosk browser.
I use the „solaranzeige“ to push my heatpump with excess PV yield and the Venus OS/node red for a simple grid friendly mode.
The stage 1 including the Multiplus was installed in my cellar staircase not knowing that it can be noisy, so I enclosed it with a light weight wall and a door. Later I equipped this with some noise canceling material. Know it looks like the chamber Harry porter lived in. Of cause if you open the door it is more like R2D2‘s home
