Victron/ Fronius 1-1 rule.

The 1-1 rule a maximum as i understand it. So there should be no problem having 3 x 5KVA MP2 in 3 phase config with 10.3 fronius Symo as the AC PV.

The 1 to 1 rule applies per phase. The Fronius 10.3 is effectively a 3 x 3.4 KVA inverter from the point of view of your multis.

So everything is shiny with your configuration
