Solar not feeding all 3 phases

I have installed a 3 phase system (3x15kVA Quattro) with 8x 250/100 MPPT's.

The system however is not utilising the solar for all 3 phases but only for the red phase which is also the master inverter. I also noticed that the "inverter on" LED is flashing on the master unit while the mains on all 3 units are solid.

Additionally it is keeping the batteries charged at all times although I have the SOC set to 30%. The other 2 phases are pulling the power from the grid.

Any ideas?

All fixed as per last post from @Alexandra

It was actually the fact that the other 2 inverters did not have the assistants loaded on them therefore it was only feeding the 1 phase.

Once I added the assistants to the other 2 units it is all functioning properly.
