Huawei 36KTL and 3 x Quattro 8000 Chargers

Good Day

I have 3 x Quattro 8000 Inverter Chargers connected to a Huawei Sun 36KTL Grid Inverter. The panel sizing only allows for a peak of 24,449KWP.


Is it possible to AC couple this system?

A hard one to answer without more information, it leaves too much of your current set up to speculation.

If the grid inverter is upstream from the Quattros? Then you may be able to add after the Quattros. Are you looking for a three phase one like a Fronius eco or a symo?

In that case you would need to follow the 1:1 rule - https://www.victronenergy.com/live/ac_coupling:start

If your grid inverter is downstream then you are already near the limit of what the Quattros can support. But you could add a DC mppt to help with battery charging.
