How much power does an Inverter use just sitting there idling?

Thats going to depend on the hardware you have. Expensive units are typically more efficent (use less power when the load is off). My 3kw "inveter" is an all in one so it has a SCC and a processor to handle load shareing with other units and a graphic display to drive etc so it consumes more power itself than a typical unit.
