There’s much backstory to write here so I’ll write like a robot to make it faster. (Or skip to Now the question)
Installed panels in 08 September 2012.
Didn’t buy companion tablet for monitor, ridiculously expensive (850€).
I monitored the system from invoices only.
March 2015 fuse tripped in main electrical panel, system went off, I had no idea.
Found out from invoice, lost 3 months of sunlight.
Did a lot of searching so I could avoid a similar occurrence. Found pvoutput.org, created account. Experimented with RPi zero, and Gen 3 later on, couldn’t make it work. Found an app for android called “Oxley Solar” it monitored panels perfectly. Been using it ever since.
Today I thought to check panel activity degradation during the years. Free app goes back only one month. Bought pro app. Noticed it has a pvoutput functionality. Found my old account, got it working somehow.
Now the question.
Can I upload the whole database from my inverter somehow?
The Oxley solar app gives me a backup feature, and an export to csv feature.
The .bak is random gibberish when read like text, so it’s a format for the app only, or certain apps.
The .csv is in normal text, and can show the daily total for all years, or a much more detailed output of per 5 minutes production for all 24 hours, but that only goes back to December 10 2021, and I think the inverter itself overwrites previous entries, which is a real shame knowing all that data is lost now.
So can I upload any of that to my system entry in pvoutput? That way I can get a better picture of my system, and also keep the hourly data.
