I’ve never seen that fault reported before (but I can see it listed in the fault codes), which inverter do you have ?

I've done a bit of research and this seems to be an occasional problem reported with the F series inverters (and often at dawn when it starts up), is that what you have ?.

I think the best plan is to contact your installer, or FoxESS support and raise a ticket - it could be resolved with a firmware update.
