This is for an on grid system that would AC couple when the grid goes
down.  Would that still void the warranty?<br><br>

Greetings Wrenches,<br><br>
I want to AC couple 8 Enphase M190s to a pair of Outback inverters,
stacked in split phase.  The use of micro inverters could allow for
great method of controlling charge to the batteries.  A morning Star
Relay Driver could be employed to disconnect one or more inverters at a
time, to taper charge.<br><br>
Have any Wrenches AC coupled this many Enphase micro inverters to
Outbacks?   Have you had any problems?<br><br>
Thank you,<br>
