    jannes258 got a reaction from Cyon in Axpert King Solar PV Output Incorrect KW   
    Good day to all powerforum users.
    I have a weird problem on my Axpert King Inverter.
    The solar output Kw that's coming from my solar panels seems to be to low.
    If I calculate the value manually by taking the PV Voltage and multiplying it with the Amps that the panels are giving out. ( Measured with a amp probe) I should then get the KW coming from the panels, right?
    But on the inverter that value is much lower.
    It seems like there is some big losses somewhere, I thought that the amps showing on the inverter was after the MPPT done it's job but the value is exactly the same as the value on the amp probe measured at the PV combiner.
    I have attached some images explaining my situation.
     
    Maybe firmware related? 
     
    Any help would be greatly appreciated!
