The sunny boys and the Cerbo GX are connected in the same local network. With some configuration in the sun boys ( Enable TCP, Modbus Server, and different address for each inverter), the Cerbo can now read information from the solar inverters ( picture showing device list). As you can see in the picture the VRM says that
1- the Load is 0 which is not true. I understand that this reading is because the load is satisfied by the PV production and excess power goes to battery. But if the Cerbo can read the amount of power being produced by the sunny boys it should do the math.
Load = PV power - battery charging power
Load = PV power + battery discharging power
2- The same amount of PV production is shown in the Generator side but with negative value as if excess power is being exported, which is not true cause input breakers are off and generator is not running.
