Two conflicting fields?

Hi,

I have the Solax X3 Hybrid G4. According to [the code](https://github.com/squishykid/solax/blob/master/solax/inverters/x3_hybrid_g4.py), there are two fields that measure the energy produced by the PV: the `"PV Energy total"` and the `"Yield total"`. Can you please explain the difference between these two values?
