The only power generating component of the system is the PV array (the modules, also known as the DC power). For example a 9 kW DC PV array is rated to have the capacity to produce 9 kW of power at standard testing conditions (STC). STC is 1,000 W/m^2 and 25°C, and is.

The inverter has the sole purpose of converting the electricity produced by the PV array from DC to AC so that the electricity can be usable at the property. Thus the nameplate.

A 9 kW DC solar array rarely produces this much power. The chart below actually shows ~4500 operating hours for a standard solar array.

Unless there are clipping losses, increasing the inverter size without increasing the modules capacity will not result in more energy output. In many cases, a 9 kW DC array of modules with a 7.6 kW AC inverter will produce an equal amount of power to.

When the DC/AC ratio of a solar system is too high, the likelihood of the PV array producing more power than the inverter can handle is increases. In the event that the PV array outputs.
