Question about using a Y splitter to divide PV equally to my two EG4 inverters.

I have 27 Phono 400 watt, 37 volt panels divided into three separate arrays of 9 panels in series. They feed two EG4 6000XPs running in Parallel with a shared Battery rack.

Currently I have it wired so one array of nine panels feeds the first inverters mppt. The second array of nine feeds to the second inverters mppt. The third array of nine feeds the first inverter on its second mppt.

My question is... Can I split (or share) that third PV array of nine panels between the two inverters using a Y splitter? So, instead of all the solar power of the third array going to the first inverter it would be split between the two inverters to pull from.

Thanks for your time.

No.

No, because each inverter has its own MPPT controller, and each will try to optimize the power point by varying its load on the PV lines. They will fight each other, with unpredictable results.
