I have had a MPPT 100/20 running for almost 3 years, and I've exported all the data from it periodically to save it in CSV files and spreadsheet. I've just recently setup a Raspberry Pi running Venus OS and integrated it with my 100/20 MPPT and a smart shunt, which is all working beautifully.
I was hoping I would be able to import the relevant historical data I have from the MPPT history into the system so I can make use of that data from the last few years. It seems I might be able to do this by inspecting the data that's stored when an internet connection is not available, formatting my data in a similar way and injecting it into those files. Anyone have any tips on doing that? where is the data stored (in what file, and what directory) when internet connection is not available?
Any tips or thoughts gratefully received.
