Observations, Thoughts and Bugs?

Happy Growatt/Hubble customer to date.  Thought I'd share some operational observations and perhaps others can add their own observations and thoughts to this thread.

340 cycles later and August it will be the first anniversary of being basically off the grid.
My Hubble BMS still reports full capacity within the SolarAssistant package. Can that be trusted?
So this morning my system shut down due to low battery voltage. It has been in Li mode protocol 52 as per the Hubble documentation since day 1, so the BMS will force the shutdown at 20% which happens to be the cutoff voltage of 42V. Thus I can only assume that the cells will not be stressed and that the only way to get more out of the battery would be USE mode and manual overrides.
Unfortunately I did not take manual Voltage readings at that time this morning.
I did however once it was fully charged. And none of the voltages actually correlate with what the Hubble specs on the battery state. 
Equalised V supposedly 53,6V and Float 52,6V.
Once my battery is full, Solar Assistant presents both the Inverter sensor data and also separately the BMS sensor data. One has to accept that as the truth in the absence of direct measurements. SA also only graphs the data from the Inverter which is unfortunate as the Battery SOC and Voltages are never the same as what the BMS reports.
Let me add the screenshots of both the Inverter and BMS stats as it was when the battery reached the supposed full capacity of 110A/h.

The Inverter states Battery has 52,3V whilst the BMS reports 52,1V
Not good enough. Took my Voltcraft multimeter and my trusted Fluke to measure on the terminals.
Voltcraft 51,7V  Fluke floating between 51,8 and 51,9V

None of these voltages come even close to the equalised 53,6V although it is preset as 53,6V in program code 19 and 20 by Protocol 52 and cannot be changed.
I thus have to assume that around 52V is actually 100% capacity and that 53,6V would be quite a bit over the maximum. Alternatively, the BMS Firmware reports a lower SOC % as 100% to prolong the battery life?  

Judging by these Voltages and the reported full capacity of 110A/h I can only surmise that this battery and the Protocol is well inside a safe window of max and min voltages and capacities which would predict a long battery life. Who knows.

Now getting back to SA and the graphing "bugs"
I have noticed that SA will continue to log and graph the last received data points, whether you shutdown the system or shutdown the Pi.
This mornings auto system shutdown is a good example. 
The SOC graph shows clearly the drop from 23% to 22% just after 7. Yes, not 20% because it graphs the SOC from the Inverter sensor and not the BMS. That 22% (20%) graph line then runs after system shutdown till where the system started up again after enough solar input just after 8. And there you can clearly see a vertical jump to 28% when it got the first data point after start up.
It just flatlines all graphs. The Battery Voltage graph is another example of this. The system and battery shutdown, yet I have a recorded constant 42V for that hour or so, until after it had started charging again.
And I have found that with all the graphs. It assumes the last received data to be valid till a new value is sensed. The lack of any values are not recorded. Not sure how the data interpretation in such instances is used to log the accumulative data which is then obviously not trustworthy.
