So here is the result of the SOC accuracy test after 3 weeks. And it is not as straight forward as you may think.
3 weeks ago, we fully charged the batteries and reset all three devices to 100%. This was the common start point for this test. Since then, I let them cycle together with the battery shelf without fully charging or resetting them again. And today, with all the sunshine, we will watch all three devices reaching 55.2V.
Which one is the most accurate, which one the least?
I have also created this graph in the Victron VRM showing the three devices in a direct comparison over the last 3 weeks. Very interesting to analyse these curves...
