After running a feed to pvoutput.org for some time I had issues with the monitoring PC and eventually gave up and let the monitoring stop.
Recently I added a second array and decided to reinstate the monitoring via a Raspberry Pi which is working fantastically.
The only issue i have found is that the lifetime efficiency calculates based on the current array configuration with no allowance for the fact the system was 3.12kw, for some time, and is now 6.24kw. Thus my lifetime efficiency is running at 1.9 when it is likely ~3.8 or so.
Is there any way to detach the old data from the efficiency calculation? I know it is a minor issue. Starting a new account would be one way to reset but I’d rather not lose all history.
Any thoughts from the community?
