9 months ago I've spent some time trying to figure out what my issue is.
Anyway I've managed to find my SOC value by brute force cutting the growatt plain data at 930. Not sure why my SPH5000 is different from other SPH5000 inverters where the "T05NNNNXSPH" layout specifies that SOC value is at 742. The value at 742 for returns 0 for me.
I now realise that the above log dump was an irrelevant part of the log, so here's a dump of the relevant part:
