Phoenix Inverter 375watt no load power consumption is 23watts

I have Phoenix Inverter 12/375 watt inverter. With no load connected to the output, the inverter consumes 23 watts from the 12V battery. Is 23 watts excessive power consumption for an inverter that has no load connected?

What are you measuring the draw off the battery with?

Yes, that is excessive. The data sheet states 5,6 W for a VE.Direct 12/375. What is the reading when you enable Eco-Mode? Do you have a Smart Shunt so you can measure the real draw?

I am measuring the power usage by connecting the inverter to the battery via a 500A smart shunt. The smart shunt is connected to a Cerbo GX. I have disconnected everything else so that the inverter is the only load connected to the battery other than providing power to the Cerbo GX.

The power usage is the same in eco mode.
