The middle graph in the image I posted IS the SOC. Literally one report to the next it goes up. Straight line.
EDIT: I was using Ah remaining and dividing because it gave a much more even, accurate representation of SOC than the classic's own SOC which rounds to the nearest whole percentage, but the classic's SOC still matches my math.


Are you referring to the middle of the 3 graphs that is labeled "power"  ?   From 0 to 100 ?

Maybe you can post again if I'm not getting it.

If that graph I am looking at is AH-Remaining then I don't know why it would do that.

Does your other SOC meter show that ramp downward before the straight up ledge around 4 AM or so ?
Yes, that middle graph is the SOC. And it's more like 80% -> 95% most of the time (the bottom limit of the graph is dynamic, so it only shows the lowest value during that time).

And no, the other meter doesn't show that. It has the steady downward slope all the way until we start getting charge in the morning, and then the steady slope upward that you would expect.
1st System: 12.5kw on 5 Classics (3 150s, 2 250s), 1 classic 250 with wind turbine, 2 stacked Magnum 4024PAE inverters.

2nd System: 1250W solar on 1 Classic 150, two DIY3024 running separate breaker boxes, one hooked up to Magnum output for AC charging.

I just looked at My Midnite and every days SOC graph looks like I would expect and no jump ups like you see.
The next days charging SOC  is steeper than the nights discharge SOC but as expected.
see example below
