Thank You.

To inverter is connected two batteries in series. The manufacturer of these batteries allows to connect up to 4 batteries in serial. Each battery haves oun built-in BMS.

Thank You. I will wait answer about USR settings.

Hi! Is it possible to connect Kepworth 12v 100ah lifepo4 lithium batteries and correctly configure the Axpert vm iv 3.6K -24v inverter to work with them? The battery does not have any interfaces to communicate with the inverter. I tried to put in program 5 (battery type) Other manufacturers - the inverter reports that the battery type is incorrect (warning 62). If I select User-Defined in program 5 (I set parameters in programs 25, 26, 29), then the inverter does not see the battery at all - there is nothing on the display where information about the battery is displayed. The only inverter began to work with the battery, if I specify the type of battery AGM in program 5. but in this case, I can't set the minimum value for the voltage of a discharged battery and the maximum value for the voltage of a fully charged battery. Advise please what I should to do. Thank You. Leonid.
