A customer has a CCGX system with 7 x MPPT BlueSolar and a BMV-700. MPPTs are connected through a 10-way externally powered USB hub. BMV is straight to the VE.Direct port. This has worked without any issues for the past year, showing all devices correctly. Recently the customer installed a set of 10 x Victron 300Ah LIFePO4 batteries with 2 x VE.Bus BMS (suggested by Victron) and 2 x Quattro in parallel.
Since the battery swap, the VE.Direct MPPT controllers have not appeared on the CCGX. My first thought was the USB hub - checked and this is still powered. Bypassing the hub (USB-VE.Direct straight to the CCGX) also does not show up the VE.Direct devices either. The BMV does show up correctly. This suggests a software issue to me.
Have tried updating all the MPPTs to the latest firmware using the bluetooth dongle and set them to the correct charge profile for lithium. Tried rolling CCGX firmware back to 2.16 (now 2.23) to no avail.
I'm aware the Octo GX is a more suitable product for multiple VE.Direct devices, however this was not available at the time and does not include the display that the customer wants. The CCGX has worked without issue with 8 VE.Direct devices for a year so shouldn't be a case of it no longer working and need replacing with an Octo.
Chargers are still charging but no communication. Any suggestions would be welcome.
