Wiring diagram - 485A1/B1 + 485A2/B2 the wrong way round? #5

Hi, thanks for putting this together... I've now got the components but querying the wiring of the modbus.

I think I've spotted an issue with the wiring diagram on https://github.com/Jumpy07/Solis---SolisCloud-and-Home-Assistant#connecting-it-all-up. If you compare the GC-1201 RS485 ModBus photo vs the wiring diagram, the 485A1/B1 and 485A2/B2 are the wrong way round on the wiring diagram.

I checked the photo of your actual build and yes it looks like the wires from the Elfin EW11 go to 485A2 and 485B2.

Am I correct... or does it actually matter?
