is it possible to connect an SMA 9 kW 3 fase connected to AC1 of 3 x Quattro 8000

We want to build an 3 fase 48 Volt backup system with 3 x 8000 W Quattro's installed. on the AC1 output we want to connect our exsisting 3 fase SMA 9000W ac grid tie inverter. As we have to deal with the 1:1 power we are wondering if this is still withing these limits as the SMA is 9kW but deverted to 3 fases and not capable to deliver 9kW on 1 fase or am I wrong in this?

Any advice is welcome.


thank you

Yes, the SMA inverter is 3kW per phase, so you are well within the 1:1 limit. you have inverter of 8kW per phase, so you could connect up to 5kW per phase more or 15kW total...
