I see that the VMiii uses the solar amps times the solar volts to get the solar W/KW. Where the King uses the solar amps times the battery volts to get the solar W/KW. Wouldn't the solar amps times the solar volts be the most accurate reading of solar W/KW?

Hi Coulomb Thank you! I actually thought that might be the case, quite interesting as the VMiii inverters with the higher MPPT Input Voltage actually shows the PV KW's that's coming from the panels itself. The current that's coming from the panels on the inverter as well as the amp probe measured the same, just thought that the input PV of 1.41KW was the power that the panels itself produced. (Charging the battery and powering the loads, the total KW that the panels were delivering) Thanks for confirming!

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!
