Lithi2-16 Battery Pack

I recently switched to a closed loop connection and experienced a very significant improvement in overall functionality. I first updated the Lithi2-16 battery to firmware RX05, using a DSD TECH SH-RJ45K RS-485 to USB cable and a Windows laptop. If Ruixu could make an app to handle this, it would be much appreciated. Next I updated the Luxpower SNA-US 6000 inverter/charger to firmware ccaa-331212, using the Luxpower app. This included the communication update ccaa-xx12xx_comm_250806.hex, the DSP update CCAA-xxxx12_dsp_251010_3.hex, and the MPPT update CBAA-33xxxx_MpptApp_260105.hex. An ethernet cable connects the OUT port on the battery to the BAT port on the inverter. In Luxpower's local configuration panel, I selected item [3] (battery definition), ”Lithium” under ‘battery type’, and ”6”（for the luxpower protocol）under ‘Lithium brand’. I then rebooted both devices. This activated a closed loop mode, where the inverter speaks directly to the battery management system (BMS). The effect is dramatic compared to using the fallback lead-acid battery definition. First, the panel voltage jumped from the 290s to 345V, lowering resistance loss. Second, I turned on a hotplate and the inverter increased energy capture from the panels instead of drawing from the battery. When I turned on one more hotplate, the inverter further increased the capture from the panels and supplemented with the battery only when the panels had reached their maximum production. This is in sharp contrast to the inverter's behavior under the lead-acid definition, when increased load would immediately tap the battery. Third, my battery would typically drop quite rapidly from 100% down to 82% by 6:30pm and stay there until morning, sometimes dropping a percent or two. On the closed loop, the voltage has been dropping far more slowly, didn't reach 98% until 6pm, and is still at 92% at 11pm. This is in part because the closed loop spares the battery and maintains full charge later into the evening and in part because the lead-acid battery definition doesn't actually know the precise charge of the battery. Finally, charging (which I haven't observed yet, as I made the changeover this afternoon) is expected to be four times faster (!!) and 95-98% efficient, compared to 75–85% with the fallback lead-acid definition. These improvements imply that the closed loop will allow the system to make far better use of the solar panels' capacity, minimize resistance, eliminate unnecessary battery charge and draw, and significantly reduce conversion losses. I'd like to express my appreciation for the excellent engineering behind this enhanced functionality.
