Hub 1 fault, low battery, EasySolr II GX

We have 2 strings of 3x 320W panels into the invertor, and 4x 12V AGM batteries in series, no grid. System has been running fine nearly 2 months, powering a very light load of a caravan, small freezer, occasional low W power tools and chargers.

Sometime around 6am it stopped supplying AC power. When I investigated I found a message "Hub-1 Fault" and the battery voltage down around 45V. My only diagnostic tool is victron connect on android over bluetooth, which shows me that solar input yesterday was 55% of usual (but the weather was bad) and battery voltages were unusually low (51.34/46.35 V).

Is the Fault message really a fault or just low battery?

Is there a way to catch battery trends like the past day by exception, a proactive notice rather than having to watch an app all the time?
