Combining Systems

I've got a Xantrex 6048 selling power back to the grid at a point I'll refer to as  the  T.  The 6048 sends power in through the bottom of the T.
The left side of the T goes into the house and the right goes to the utility.
When the house doesn't need it, the utility takes it.
I'd like to add some micro-inverter/panels to the system by installing them on the garage roof.
The power from the micro-inverters would be attached to the left side of the T.
Will I have an anti-islanding problem with the two systems seeing each others power?
Are there other conflicts?

Re: Combining Systems

The grid tied inverter is synchronized with the grid AC voltage. I would think you'd have a problem interfacing your micro-inverters unless you found some way to sync their output waveform with the grid.
