I have some issue on power indicators in my Multiplus-ii Gx
My system:
No break loads =0W, Loads=0W
When i ask the remote console I get:
The Grid Find-in is arround Twice the PV Power and the Grid value on the Gx LCD is arround -600W
I assume the Grid value on the LCD is the ACin1 measurement
So why there is Power that is feed from the Gx ?
It is fixed. Setting the PV inverter to AC Output fixed it
Settings -> PV inverters -> Inverters -> AC-OUt L1 -> Position -> AC Ouput
Hi @michelP
You've configured the PV inverter on the input, but you have to configure it on the output in the settings.
everything 'behind' the current sensor is measured as on the output of the Multi.
Hi @Daniël Boekel (Victron Energy Staff)
To be shure on my understanding I need to move my PV to the ACout (only in the software) there are still connected to the AC_in
Does this apply also for the loads ?
I have move the PV to output and it's ok
But for the lood that are on mains this is'nt good
Does this rule also for the loads ?

Hi @michelP
Please read the ESS manual first:

Also: your system is in pass-thru, is that intentional or is something wrong?
Hi @Daniël Boekel (Victron Energy Staff)
I have reading again the ESS manual in summary regarding my main issue :
In my system I hope measuring the Grid by the current sensor on it this is not the case ?
Hi @michelP
In my experience, power measurement by just the Multi's / Quattro's is accurate enough for most purposes.
a grid meter is more accurate, but most systems don't need the greater accuracy.
@michelP did you ever got this solved ? i have the same situation. The PV is physically connected to 'AC-out-1' and in the ESS assistant i configured a PV connected to 'AC out'. I use the internal power meter of the Multiplus II GX. There is nothing connected on the 'AC-in' side , accept the Grid. But i also see double the solar power display in the console app feeded back to the grid. The display on the MultiPlus shows the correct power feeded back into the grid. Exactly your issue.
