CCGX loses connection to VE.direct Charge Controller 90sec after reboot

EasySolar 24/3000/70 Mppt 150/70 that we installed for an off grid client. The system has been installed and working fine for 2.5 years and then suddenly the PV Panel does not show on the CCGX display, device list shows "MPPT not connected". However, the MPPT charger is fine and is charging the battery.

A reboot of the CCGX always brings the connection to the MPPT back to life, however after 90 seconds it loses the connection again. This behaviour is repeatable with loss of connection about 90 seconds after a reboot.

There is no USB hub or VE.direct extension cables in the system and this is the original Victron-supplied VE.direct cable that has up till now been working fine. This is an EasySolar system with the VE.direct cable prewired inside the EasySolar. This is a single EasySolar system with no other devices.

I have unplugged and replugged both ends of the VE.direct cable and the problem is still there. No firmware updates have been done as this system is not internet connected. Is this a cable problem or something else? Why would there be a fault now after 2.5 years of good operation?

Hi @MartinD Have you tried using the other ve.direct port on the CCGX, another cable, a CCGX reset and as a last resort a mppt reset even? (don't forget to backp/record any custom settings) There are so many possibilities as to what can go wrong from HW issues to corrupt memory segments etc etc. Prolonged use combined with heat, humidity and electricity may also eventually expose HW weak points. It may also be of interest to update all the firmware if an opportunity presents itself. If by process of elimination you can identify, which component, you can call on the 5-year warranty if it still applies. Hopefully it is just some software going a bit rogue and is begging for a reset and upgrade.

It turns out the CCGX was faulty. Replacing it fixed the problem
