We disagree on that, V is not SoC, especially over time.[/QUOTE]
Well, we can disagree on that.
In my experience, for all practical intents and purposes, for a 12 Vdc FLA bank on the hook...
When one wakes up in the morning before the sun shines on the
panels, if the bank reads 12.2 Vdc or more, all is well.
If they read higher, fantastic, the more the better. If they read less, capacity or
charging was insufficient.
About sunset, if the bank reads 12.7 Vdc, all is well. If it reads less, there's a good chance the bank wasn't fully charged.
If conditions are the same tomorrow, start the alternate
charging system to put more in the bank, so it will be fully charged, by sunset.
As experience is gained with the bank voltage under various charging and draining conditions, one learns to judge by about noon, if they will have to put more in the bank than the
solar is likely to deliver, to charge fully by sunset.
Whether one has a display (of questionable accuracy) in A-hrs charged or consumed to 2 decimal places, is really of little additional value.
Notwithstanding, if any customer wishes me to supply and install a
battery monitoring system of any description, I'll gladly comply.
On my personal
boat, I have a digital voltage reading on the
chartplotter display at the
helm, and on the inverter/charger display at the nav station, so I know where my bank is at all times.
