The internet at the customer site went down as did the mains power., The system was functional during the whole time as there are 10kwh LiP04 batteries and virtually no load to speak of. The internet connection is back up yet I have missing data for about 15 days.
Set up is 36 x 320W PV Panels 5kva Multiplus, 3 x 150 MPPT, GX Colour Control, 10kwh LiP04 battery. What could the reason be for the missing data. We log every 15 min and do not have a micro SD card installed yet have 26.43M bytes of free disk space. Will adding a SD card help and if so what is the recommeded size?
