Question about idle power consumption

[Jak]

If an inverter uses 40 watts idle power consumption, and I have a constant 40 watt load. Like a router & modem. Will the load be 40 watts + 40 watts? Or will the inverter put the idle power consumption that would otherwise be wasted towards the appliances?

It will be additive. No inverter below 3kw will be using anywhere near 40w though. Usually around 8-15w.

Thanks for the quick answer. I'm looking at the PDF for these sigineer inverters.

3000 Watt 24 Volt to 100V 110V 120Vac DC to AC Pure Sine Power Converter Charger

3000W Pure Sine Power Converter, converts 24V to 100V 110V 120VAC. Built with smart battery charger of 50 amps. LF transformer inverter, 50Hz 60Hz output.

www.sigineer.com

It states
"The idle consumption of the line is low, roughly 4% of its rated power."

Which would be 120 watts & seems like a huge deal breaker. Am I not understanding something correctly?

Says 13w idle power saver mode. Thats what I would expect.

Some Converters have a remote switch to turn them on and off
