Could it be subtracting standby power used at night when the inverter isn't producing energy? I doubt the inverter uses that much power in a year while it's asleep though...
I have a Sense energy monitor which uses CTs and the solar production figures are lower than actual because it subtracts the negative readings from when the inverter is in standby.
They're also not 100% accurate - I've noticed that when I'm pulling lots of power from the grid overnight (e.g. when charging my car) the solar CT negative reading increases... probably induced voltage confusing the CT?
Cheers. My main concern was the PVO league tables. Ha
