In my 48V ESS system, I use 2 groups of 2 24V batteries connected in series, in parallel. I have provided a Smart Shunt in each group to monitor the SOC and the midpoint deviation. The batteries have their own battery management system integrated and communicate via minor voltage and current differences.
Unfortunately, I can only specify one device in the battery monitor. As a result, the battery's charging capacity is only half of what it should be.
How can I configure a virtual battery monitor that displays the sum of both currents and the mean value of the SOC and voltages as Battrie SOC and voltage?
