Hi Gang,

Fellow PV Techies -
When designing an AC coupled PV system using Outback: Am I correct that the
battery bank can be minimally small, as they are just there to power the
GVFX Output and mimic the grid for the grid-tied inverter of choice?

I have a client whose Trace DR 1524 inverter (yes, it's an old system) fan

Does anyone have experience with something like this?

I've done 3phase with 6 Schneider Conext XW. It worked well but when you
convert to 3-phase you lose surge capacity because you are turning the
inverters into 120V inverters from 240.
