An inverter is not the same as an AC contactor, but they are related components in electrical systems.An inverter converts DC (direct current) to AC (alternating current) and may contain an internal AC input contactor to manage power flow1.An AC contactor is an electromechanical switch used to control the supply of power to loads, such as motors and lighting systems2.While inverters may use contactors for their operation, they serve different functions in electrical systems4.In summary, while they are not the same, inverters can utilize AC contactors as part of their functionality.

The capacity of an inverter is the maximum power output it can handle, usually measured in kilowatts (kW) or kilovolt-amperes (kVA). The goal is to match the inverter capacity with the solar array's size (in terms of power output) and the load (electricity demand) to ensure optimal performance. [pdf]

To boost the power output of PV cells, they are connected together in chains to form larger units known as modules or panels. Modules can be used individually, or several can be connected to form arrays. One or more arrays is then connected to the electrical grid as part of a complete PV system. [pdf]

The capacity of a battery is the amount of usable energy it can store. This is the energy that a battery can release after it has been stored. Capacity is typically measured in watt-hours (Wh), unit prefixes like kilo (1 kWh = 1000 Wh) or mega (1 MWh = 1,000,000 Wh) are added according to the scale. [pdf]
