After rebuilding the attic of my house I came around to reinstating the logging of my SMA inverter through SBFspot on a Raspberry Pi yesterday (https://pvoutput.org/list.jsp?userid=17849).
I used the PVOutput CSV loader to load the missing daily values which I got from SMA’s Sunny Explorer (with a quick compare with SMA’s Sunnyportal values). All daily and monthly values on PVoutput once again correspond with the values of the inverter. All is well. However, the PVOutput ‘system lifetime generation total’ still stands at 24,01MWh where the value should be ˜28,36MWh. Is this value recalculated batch-wise every once in a while? A manual sum of PVOutput’s yearly values equals 28,36MWh showing that the monthly/yearly values are correct.
Thanks in advance for your help.
Thanks for the info.
