[FAQS about Australian high-frequency inverter installation]
Because the PV array rarely produces power to its STC capacity, it is common practice and often economically advantageous to size the inverter to be less than the PV array. This ratio of PV to inverter power is measured as the DC/AC ratio. A healthy design will typically have a DC/AC ratio of 1.25. .
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. .
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,. .
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. [pdf]
