Hi. Hoping for some remote support. Following a firmware upgrade to 2629_552 my GX restarts about every 2 minutes. The GX is running v3.33. It seems the inverter is working fine - there may be a problem with the GX board.

Multiplus-IIGX restarts every 2 minutes
@Ertcom Why did you update the firmware? First ensure you have uploaded the settings file after the update (all settings are reset to defaults), but I will suggest you roll back to the previous known working version you had which will require a dongle.
The settings file was uploaded OK after the update. Looks like the last stable version was 508. I will try to roll back. I assume the GX device is OK to remain on the latest (3.33)?
Rolled back to last know working version 508 - no change, GX reboots. Settings file reloaded with last known working version, GX reboots. Rolled back nanopi VenusOS version to 3.10 and still reboots. Looking like a hardware fault.
The GXcan be deliberately set to reboot when VRM connection is lost. Check you don't have something crazy set there..
No unfortunately. Also when it reboots the GX displays Hub-1 OFF.
I disconnected Grid and ACOUT from the Multi to see if there was a wiring or grid fault causing the reboots. Even on battery the GX is rebooting - every time the unit reboots it sends a new alarm to VRM for loss of grid. I think there's a hardware problem.
Looks like an alarm relay is triggering a fault condition causing the reboot. Does anyone know where the alarm relay is on a Multi-IIGX?
