My issue is random and intermittent, works fine until it doesn't and there are no error codes being logged.

Do you know if this happens before or after the grid relay engages when grid power is restored?

Have you tried to extend the time delay between when grid is restored and the inverter reconnecting to the grid?

If you can simulate the behaviour by dropping and reengaging the grid with your change over switch the problem is likely localised as opposed the being caused by an unstable grid supply.

No, it happens without any grid issue. Happened again this morning at around 2:18, grid was stable.

At least it did log a fault this time, and it does seem to be the F18 AC Overcurrent fault, although that does seem to be misleading as it was the middle of the night and nobody was using anything, the stats in Solar Assistant show nothing out of the ordinary, only that there is a blip where the inverter shutdown for those 30-60 seconds.

There are a lot of results when searching for the F18 error online but they all involve the grid coming back from an outage, in my case it's just happening randomly.
 
Anyone had the screen and LEDs die on the front of your inverter?

My wifi module expired and now this.
 
I contacted Sunsynk for the firmware upgrade, they couldn't for some reason perform a remote update (maybe my firewall rules are too strict) but they provided me the firmware files and instructions - seems pretty simple. Will do it this weekend.

Good luck. I always have cold shivers when I do firmware upgrades.
 
Did everyone else also receive these error codes yesterday (27-October)?

I saw a post on FB of someone posting similar warning codes on their SunSynk as well.

Seems to be a syncing error between the device and the SunSynk servers?
