Which PV inverter ratio should I choose
DC/AC ratio refers to the output capacity of a PV system compared to the processing capacity of an inverter. It’s logical to assume a 9 kWh PV system should be paired with a 9 kWh inverter (a 1:1 ratio, or 1 ratio). A PV to inverter power ratio of 1.15 to 1.25 is considered optimal, while 1.2 is taken as the industry standard. [pdf]
PV inverter communication connection requirements
Each inverter must be connected to no more than one PV module. The thresholds for the input voltage and the input current of the inverter must be adhered to.. Each inverter must be connected to no more than one PV module. The thresholds for the input voltage and the input current of the inverter must be adhered to.. The inverter must be connected to the local network via a network cable (e.g., via a router). [pdf]
