I have two MPii's 3kVA in a parallel setup with two Fronius inverters. I have a 2.5kW Galvo on the ACout of the Multi's and a 4.6kW Primo on the AC-in side. I also have DC coupled PV.
With the battery still under 70% SoC, the Primo's output is being cut back while the Galvo's is not. If I switch on "feed in excess AC coupled PV", the Primo ramps up to full output and the Multis ramp up charging to match so there is still no actual feed in happening.
Is this a bug or have I done something wrong with my setup? The behaviour I expect is that the Primo should only cut back if the battery is full or if the charge current limit is reached, neither of which is the case here.
