Battery SOC Curve

Sunsynk 8kW

2x 5kW Freedom Won eTower

Grid charge disabled. 

Noticed this morning in SA that my batteries SOC seems to randomly fluctuate. 

Is this normal? 

Day View: Note the small spikes then frequent spikes there after.

Zoomed: High Point 38%, Low Point 34%

Yes, that is fairly normal. The SOC is the result of an algorithm that calculates the approximate state of charge. There are many factors that influence the state of change such as temperature, cell chemistry, age of batteries, speed of discharge, etc. It is virtually impossible to calculate it 100% accurately, so what you are seeing is an estimation and is perfectly fine.

Thanks @HendrikBigChief. Weird I haven't noticed this before 😄
