If I select Pylontech in Program 5 as the batery, the battery icon on the LCD flashes in line and battery mode. If 1 select user defined battery and add the following parameters

(05) User select, 

(02) 30A

(12) 48V

(13)51V

(26) 53,5

(27) 53,2

(29) 45

When this selection the battery icon is stable but the lCD charge indicator shows the battery is 78% and charging but the Pylontech US3000C shows it is fully charged. What am I doing wrong.

This is normal, it tells you that the battery BMS is communicating and in control.

What you are doing wrong is believing the inverter's estimate of the battery SOC. It's doing a rough guess based on battery voltage, and assuming that it's a lead acid battery. Go back to battery type PyL, and the SOC should be as sent from the battery. The flashing battery icon is your friend.

I spoke to other Axpert users who told me their battery Icon is stable. The reason why I asked the question is that I could not find any information on the flashing LCD battery icon in the user manual or on the internet. Thank you for your response and I will respect my friend.

With PYL selected in program 5 the maximum charging current in program 2 is fixed at 10A and cannot be changed to 30A as proposed on the Pylontech data sheet. Is this normal,

It is in fact normal for the Pylontech BMS to "take over control of" the battery settings, including setting 02 (maximum total battery charge current). It might be 10 A now, but in other circumstances it could change to 30 A or other values, as the BMS firmware decides. Hopefully, it knows best what you battery needs at any moment.

Coulomb is correct.

The BMS is changing it. If battery is at a low state of charge it will be higher than when it is almost full.

The Only setting you will be able to change is the charge current from grid setting.

Thanks for your support. Everything is working and I don't notice any changes in the  Eskom supply. Still can't understand why the flashing Battery Icon, which indicates the system is working correctly, is nowhere referenced in the inverter documentation or on the internet.

It's in Appendix B of later manuals, which refers to BMS communications.

Thanks

Joining the party late. If i understand correctly if its annoying its fine just like my wife describes me :).
