No worries. It’s been very interesting following your progress. Yes, single-phase charger. I don’t think any BYD vehicles have 3-phase charging.
With BYD, the PP pin is not required for V2L. I’m not sure why, but that’s just how they determine whether the V2L adapter is connected.
The resistor value is 2k Ohms. (I also measured it to double check) Sorry, the colours in the photo are a little hard to judge. You can see the full details here… BYD Atto 3 V2L load testing - Vehicle-to-load power output
