An inverter is not a battery. It is an electronic device that transforms a DC current (taken from a battery) into an alternating current (AC) at a given voltage and frequency. An inverter is an indispensable item to use to power electrical devices that work in AC, using a DC source.
In multi-inverter modules in parallel, all the outputs of the modules are connected to the same point and transmit power to the load ZL. Therefore, the load current is the sum of the output currents of the n (denotes the number of the inverters) modules, and the average current iav of the parallel system is the 1/ n of the load current.
