Hi I have an (off grid) EasySolar 48/3000/35 Mppt 150/70 the CCGX has stopped showing PV Charger, When I have rebooted and it will appear on CCGX for about 90sec then disappears, the solar charger is still working (can see it on Bluetooth Dongle) and voltage at battery is showing so too. As the PV charger is not showing on CCGX it is not showing correct SOC either.
I have also changed ve direct ports on back of CCGX but no different.
help : )
Hi @Mike45 First question I always ask is, has anything changed? Firmware update? Which software versions are the devices on? Are the connections at the MPPT still fitting ok? I'd disconnect the mppt too, reboot the cgx without it then reattach and see if it picks it up.
No firmware updates as everything has been going good until this, so will look at doing updates, connections seem good, and did reboot without Mppt it did pick it up when reconnected but only for 90sec then gone. System been running for 2years. Maybe new cable needed.
I also have this exact same problem on a 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 show "MPPT not connected". 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?
It turns out the CCGX was faulty. Replacing it fixed the problem
