3 phase AC coupling

Post by CharlesM99 »

Is there a way to make this happen?
We have a 3 phase 208/120 grid tied PV system, but we'd like to offer battery backup for some 3 phase loads & ideally keep the PV capable of recharging the batteries when off grid.

Is this an option with Outback equipment?
I see the FXR inverters can be stacked to create a 3 phase grid, but can we tie in an existing PV system on the load side? It doesn't look like this inverter can Frequency shift?
