Question

I was playing around and downloaded the logged data in a .csv file onto a flash stick via a USB OTG. I had a look around the forums to see if anyone has posted the correct parsing but could not locate it. This is my interpretation, does anyone know if any of the fields are incorrect? Any idea what the field between Output Hz and Battery voltage is?

I plugged in a USB flash stick (formatted FAT32) using a microUSB OTG cable. Press and hold the top left button next to the screen until the USB menu comes up. Then select Log and yes using the buttons next to the relevant option.

Hi Shadders

Did you have any joy in identifying the unknown field?

The SOC column in your log looks very similar to mine, showing the SOC dropping from 100% down to about 50% the moment the GRID power stopped. Any idea on what is going on there?

Thanks for the column info, it's a great help.

I use a lithium battery so the cut-off and bulk charge values are very close. The inverter "measures" SOC by using the terminal voltage so as soon as grid power drops/battery leaves float the SOC reading drops like a stone because it assumes a linear relationship between SOC and the voltage. This is not the case over the range programmed into the inverter.

Looking at the data again I think it's the decimal points for the frequency. Nothing else makes much sense.

I'm glad the information has been a help๐Ÿ™‚
