Have a Color Controller GX with
1 - BMV-712,
1 - 12/3000Multi Plus.
2 - SmartSolar 70/30
VE bus connects the Multiplus to the CCGX
VE Direct connects BMV-712 to CCGX
Each smart solar connect to a VE Direct to USB which combine in a hub and are connected to one USB port on the CCGX.
Color controller is malfunctioning for a week now and constantly rebooting. Furthermore CCGX will not display solar charging information. CCGX also reported false notifications that the 12/3000 multiplus battery temperature warnings; the 12/3000 has been shut off over this time.
I seem to think the CCGX needs to replaced? It is 6 years old now.
