We have a victron mulitplus inverter so that we can always have AC if we want.
Let's say we have a device on 12v that states it uses 120watts, this would mean the amperage is 10Ah (120/12). So if this device is on for an hour it will extract 10amps from the batteries.
How does this work if you have a 220v device that also uses 120watts. Will it still be those 10amps (plus a bit of inverting loss?). Or am I completely wrong here?
Hi. Yes if your battery is also 12v its also 120W when inverting to 220v, so 10A, if youre battery is 24v its also 120W but 5 amps when inverting to 220v (losses not calculated!)
I'm confused. I thought that if you use 220v and your device takes 120w, then you will need ½ an amp (i.e. 120/220).

There's also a standby draw with no load. See your inverter's data sheet for this value.
