An inverter typically draws between 1-2% of its rated power as a no-load draw. This minimal power usage maintains internal circuitry and readiness for load application. The amount of electricity consumed by a battery charger (inverter) when it is plugged into the socket is known as idle consumption. This is known as a no load current although the energy drawn is only 2 to 10 watts n hour. There are some times that there is no load. Does the inverter still consume the same amount of power then? Or significantly less because it is proportional to the load? It's hard to tell since my usage watt meters are downstream after the. . A standard power inverter can draw between 5% and 10% of its wattage even with no load.
