I finished my camper setup but unfortunately it´s not working as expected. If I connect a Induction hob with a consumption of 1700W, after 2-4 minuts the AC voltage is switched off because the Multiplus restarts. If I start cooking with the hob, the voltage of the batteries is approx. 13.4V at start timre The voltage drops slowly during operation, the current (DC side) is 60-70A per battery pack, in total approx. 130A. After 2-4 minutes (the time varies) the voltage drops to approx. 13V. As soon as the voltage drops below 13V, the Multiplus 12/3000/120-50 switches off the AC supply and the error message appears in the Cerbo GX: **Low battery Voltage** **Settings in VE Configure:** DC input low shut down: 11V DC input low reset: 12V DC input low pre alarm: 12V **Settings in Cerbo GX device:** DVCC is activated: SVS – Shared voltage sense = active SCS – Shared current sense = active SCS status = Disable (External control) Controlling BMS = Battery Aggregator **System-Setup:** Cerbo GX 2 JBD BMS each with 4x EVE LF280K cells, together 560Ah. From EVE datasheet: Cell Full Voltage 3650 mv / 14,6V Cell Minimal Voltage 2500 mv / 12V Standard charge and discharge = 3.65 V/2.5 V = 14,6V / 10V Cut off voltage of charge / discharge = 3,575V / 14,3V Regarding datasheet from batteries, BMS and Victron as I understood it should be not a problem to run the system with a continuous current of up to 200A. Hope someone can take a look at my setting and maybe give me some hint to solve the problem. Thanks a lot! ![01_Allgemein](https://europe1.discourse-cdn.com/victron/original/2X/1/17cf2c2d0cb7d489d63b6c72595f8ba1db1ae815.png) ![03_Wechselrichter](https://europe1.discourse-cdn.com/victron/original/2X/1/121b1b401492c6be25c675e29317c8cafc94f931.png) ![04_Ladegeraet](https://europe1.discourse-cdn.com/victron/original/2X/7/7c78416530173d9224a30e6b33825198f30b3a94.png) ![5.1_Virtueller_Schalter](https://europe1.discourse-cdn.com/victron/original/2X/1/15ea90df64363297fc16a613955efc3691443ebf.png) ---

Hi, thank you very much for your help. I will check and post the results here. ---

@lxonline As I understand the voltage which I can see as Touch GX under section “Multiplus 12/3000/120-50”, is referring ve bus terminals. However, if DVCC is activated, voltage and current are the same values like “Battery Aggregetor” and voltage are the same like in each separate “SerialBattery”: ![Screenshot 2024-10-16 114204](https://europe1.discourse-cdn.com/victron/original/2X/c/c0e7b878b85a0d42a3174dac79500c9151e91ccf.png) @Marcel-Vanlife Thank you very much for your help! Thks to your comment I could solve the problem. To do a test run, I just bricked the fuse. So I could run 200-240A over 15 minutes. Great! I will change the fuses. ---
