ESS assistant difference ph. 1 to ph. 2 & 3 + underestimated PV production

Dear all, i am dealing with large fluctuations when my solar system on the AC-OUT is in full sun (more than 4000 watts production). My total Solar capacity is about 11000 watt (one 3 phase SolarEdge system and a 1 phase Hoymiles system on phase 2). I have checked my setup and wonder if i have made a mistake and this is causing the fluctuations. The settings on the ESS assistant mention 7500 Watt installed solar power and this is on Phase 1 only, Phase 2 and 3 are an abbrevation of the phase1 settings (see below). Would these two mistakes possibly cause fluctations in my system ?

My system is 3 phase MP 5000, 4 wired 3 phase grid (with neutral) and 6 5000 Pylontech batteries attached.

The assistant is asking for the TOATAL installed power.
Total means over all three phases not only L1.

L1 is the master unit, it’s normal that L2 and L3 have fewer options.
