PV and inverter ratio

A 1:0.8 ratio (or 1.25 ratio) is the sweet spot for minimizing potential losses and improving efficiency. 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.
