I have a cerbo gx, rec bms, a 100/50 mppt, and a 150/75 mppt. Started with just 100/50 everything worked fine. I added the 150/75 and 2 Panasonic vbhn340sa17 panels got a DVCC firmware 48 warning. I went to the VRM portal to update firmware both mppt were on my device list but trying to up date the firmware it said there were no undateable devices. I deleted my 150/75 to see if that would fix the problem. It didn't. Now I can not get it back on my device list. The 100/50 has now disappeared from my touchscreen and is not sending data to the VRM and is not in the cerbo menu. help.
