Growatt SPH10K BH-UP not respondig

[ssditt]

I try to apply this solution with Growatt SPH10k BH-UP hybrig inventer. I cannot get any response from the inverter.
Using osciloscope I see the data are repeatedly sent to inventer on the 485 link, but there is no response visible (and nothing in serial monitor).
Using 485-3 RJ-45 port on inverter, pins 1-B, 5-A
Slave ID is 1 as on the other Growatt inverters, speed 9600, checked in inverter registry.
What to do the get it worked?

You can try swapping the A and B lines. But I have written this for more basic Growatt inverters. Hybrid inverter is a lot more complicated device, I it is likely that the inverter is using a different set of registers. So even if the communication works, the data you get from the inverter will be unusable.
