How are inverters rated?

Inverters are rated in watts because this measurement indicates the maximum amount of power the inverter can supply to connected loads. The wattage rating reflects the inverter's ability to convert DC (direct current) from a battery or other source to AC (alternating current) for use in various applications, such as household appliances or industrial equipment.

When determining the size of an inverter for specific applications, it is essential to consider the total wattage required by the devices that will be powered. This ensures that the inverter can handle the load without overheating or failing.

In contrast, volts refer to the electrical potential difference, amperes measure the flow of electric current, and ohms indicate resistance in a circuit. While all these measurements relate to electrical systems, they do not adequately reflect the power output capacity of an inverter as watts do, making wattage the appropriate and standard rating for inverters.
