Similar issue to https://community.victronenergy.com/questions/19635/connecting-two-vebus-inverters-to-color-control-gx.html.
I successfully connected one Quattro inverter/charger (24|5000|120) to my Color Control GX with a VE.Bus connection and was able to set it up. I just got my second Quattro installed, but no matter how I cable them together, I can't get the CCGX to show two inverters. As long as they are connected to one another, I get one or two errors:
#25 Firmware incompatibility. I can't get the CCGX to recognize the second Quattro, so I can't get it to update.
#17 Phase master disconnected(?)
My goal is to configure the Quattros to run split phase 240V, but I can't get them to work together or with the CCGX. Any ideas?
