Question: Growatt SPH inccorect consumption data

[Fincut]

Hello friendly forum!

I have the following PV system:

14x 410w modules
Growatt SPH 5000
Growtt USB Data Logger
Chint DTSU 666 Smart Meter

I have NO battery

I have connected the smart meter to the inverter (pin 24/25 on port "meter").

My problem is the following: According to the app "ShinePhone", my power consumption is always exactly double what my system generates. So if I generate 2.5 kW, the app shows the following:

Generation: 2.5 kW
Grid consumption: 2.5 kW
Power consumption: 5 kW

The power consumption and grid draw is definitely not correct. The curves of generation and power consumption are absolutely symmetrical. If the generation decreases for a short time because of a cloud, then the alleged power consumption also decreases

What did I do wrong?

Thanks a lot!

Have you set the inverter options for meter rather than CT clamp?
