ABSTRACT:
In the current invention, in order to increase efficiency of battery powered AC electricity supply, multiple inverter/battery modules are used in parallel but can be individually shut down. The number of inverters activated depends on the power usage. When only a little power is needed only one or a few inverters are activated. When more power is needed the battery inefficiency increases and more inverters will be activated.
