Multiplus2 48/5000 GX installed as ESS in Nov 2020 working fine until 6days ago when communication stopped as well display froze and system went into passthrough. Rebooting system brings back normal operation, unusual slow takes 4 to 10min). It than stays on for 10min to 1 h before Wifi communication freezes, screen on multiplus 2GX changes to blank, and than displays VictronEnergy. System resets itself randomly after 10min or as long as 2h (as so far observed). But than freezes up again and goes to passthrough.
It also appears that system freezes within a few seconds after connecting ethernet cable back in GX card.
Actions taken: Upgraded GX firmware to latest v2.93 from original 2.72 (upgraded via USB slot as ethernet port does not communicate)
Manual reset the system a few times. (by fully de-energizing system from AC and DC)
Also checked internal GX card appearance and cable connections. All clean and tight.
It appears that GX card needs attention?
Any suggestions would be highly welcome.
