System Configuration: Inverter Model: Deye SUN-50K-SG01HP3-EU-BM4 (Hybrid High-Voltage Inverter). Battery System: 2x Pylontech PowerCube-M1-C Racks. Total Battery Modules: 44x H32148-C modules (distributed as 22 modules per rack). Battery Management System: 2x SC1000-200J-C high-voltage BMS controllers (1 controller per rack). Proposed Topology & Design: I intend to fully utilize the inverter's capability of having two completely independent battery ports (both Power and BMS communication ports), thereby eliminating the need for a central MBMS1000 controller. To achieve this independent dual-rack configuration, I plan to implement the following setup: BMS Address Configuration (DIP Switch Settings): Rack 1 (BMS 1): Set Address to 000001 Rack 2 (BMS 2): Set Address to 100001 Hardware & Communication Wiring: Rack 1: Connected directly to Battery Port 1 (Power Port 1 + BMS Communication Port 1). Rack 2: Connected directly to Battery Port 2 (Power Port 2 + BMS Communication Port 2). Technical Inquiry: Is this configuration feasible and safe to implement? * Will the inverter correctly recognize and manage both BMS units independently via Port 1 and Port 2 without causing any parallel synchronization faults or communication conflicts? Could you please verify if the current firmware version for this specific S/N supports this setup, or if a remote firmware upgrade isrequired?

It is true that the settings for 12, 13, 29 were set based on SOC%, but what appears on the inverter screen when turned on is the battery voltage, and I cannot get the SOC% storage percentage. This is strange because in deye devices, I can do that, but in voltronic, I can only set the settings in degrees Celsius.

Can the Voltronic Expert Max E 11kw read the soc% of Pylontech uf5000 batteries (five batteries) via RS485, knowing that I set the function 1=SBU12=10%, 13=15%, 29=5%? Or read voltage from dc bus?? Is this values reasonable? And if utility power always exist, does inverter use utility onley between SOC%(10-15)

Just one battery Message 69 always appears on the inverter screen, but it can only be discharged. I waited until the battery reached 30% discharge and the message did not disappear. Note that I set 1 sbu 2 50A 5 lib 12 20% 13 40% 16 oso 26 55.8 27 55.8 29 48

In the battery screen

I connected a Restar company 5k lithium battery to an axpert-vm-iii-6k-twin-off-grid inverter and after a few seconds an error 69 appears even though the battery screen shows that the charge percentage is 50% Can anyone solve this problem?!!

What about flooded batteries, I set as below: 1- SbU,2-20A,3-UPS,5-Fld,12-46,13-57,16-OSO,26-58.4,27--54,the reminder I leave it as default
