Multiplus II no load consumtion are too high

My new Multiplus II 48V 3000VA draws 0.89A at 52V when no load is connected. That is 46 watts. In the specification, it should draw 11 watts. Is my device broken?

I have double checked and triple checked with different measurement methods. And even the Multiplus and BMV tell me 0,9A.

I bought this specifically because it would only draw 11 watts compared to 40 watts that my old inverter draws as I have limited space for solar panels and the inverter need to be on 24/7.

This one draws even more than my old cheap chinese inverter.

Any suggestions? Or is it just to return the device?

It depends on what setting your have.

Is AES enabled?

@Kirtap Is the system completely off-grid? Have you disabled the charger in VE.Config and see what happens as well as disabled power assist? It states the inverter draw is 11W but this is an/inverter charger so the system overall could be higher. Just some thoughts.

@ejrossouw Thanks for your thoughts. The system is off grid intended for a motorhome. I have now tried to turn off charger, ups, power assist and wide input frequency but still 0,89A stand by current. I had a multiplus 1200VA in my caravan, that multiplus draws stand by current acordingly to specifications.

The seller dont answer my questions. Any victron staff here?

I interpret it as it draws 11 watts in normal mode. 7 watts in AES mode and 2 watts in search mode.


If I turn on the AES mode it still draws 0.89 amps but maybe it gets a little quieter. Search mode draws 0,89 amps for a short time period about every 2 seconds.


I already have a 375va inverter and an 800va inverter from victron and they draw idle current according to spec.


I have now also noticed that the included temperature sensor shows errors with +7 degrees C.


Has the quality of victron stuff gotten worse?
