The transition of DC to AC power is called an inversion, while the less common AC and DC transition is called a conversion. Both have different energy flows, but a DC-to-AC power inverter is sometimes necessary for a household. The typical electricity supplied to homes is 120v-240v in AC.
To translate DC to AC power, you need inverters. Various electronics have an input of either 12, 24, or 28 DC voltage, and in order to use appliances with an AC output voltage, you must have a power inverter. Among the more practical applications of AC inverters are the following:
Typical DC-to-AC inverter loading ratios have increased from a range of 1.15–1.25 to a range of 1.3–1.7. DC Voltage drop is power lost as it travels through conductors from the array to the inverter input terminals. The loading ratio refers to the ratio of the actual load to the rated capacity of the inverter.
DC voltage drop refers to the power lost as DC voltage travels from the array to the inverter input terminals. It is generally desirable to minimize these losses, as less DC power input to the inverters results in less AC power output.

With an oversized inverter you will have more capacity to convert DC to AC, but unless you plan to add more PV at a later date, the oversized inverter would likely be an unnecessary purchase.

In the event that the PV array outputs more energy than the inverter can handle, the inverter will reduce the voltage of the electricity and drop the power output.
