Hi
I have been trying to get a system properly running, however somehow, the direction of energy seems not logical.
Setup :
3 x Quattro 48/15000
1 x Fronius Symo 10 , connected to AC-Out
1x Carlo Gavazzi meter connected to the grid.
The house has critical loads, which are connected to the AC-out, and all other loads are connected to the same place where the AC-in of Quattros are connected.
1st try:
The external meter is configured as grid meter. ESS is configured , Grid metering is selected as the inverter. Excess power is limited to feed-in upto 3000W. Here the sum of energy doesn’t make sense.
2nd try :
the external meter is configured as grid meter. ESS is configured , Grid metering is selected as the External Meter. Feed-in is disabled. Here also the energy sum doesn’t make sens
3rd try :
the external meter is configured as ac meter. ESS is configure , Grid metering is selected as the inverter. Feedin is allowed upto 3000 W , imagining that the other consumers need that. here the sum makes more sense.
However what we want is, that solar can feedin all consumption (critical + normal) and doesn’t feed back to grid anything.
any help would be welcome.
