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). But that's not the case. Most PV systems don't regularly produce at their nameplate capacity, so choosing an inverter that's around 80 percent lower capacity than the PV system's nameplate output is ideal.
