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?
