[RE-wrenches] Convert Grid Tie SW4048 to Backup System; Add New Inverter, AC Coupled

[Nathan Jones]

Bill,
I believe Allans post indirectly answered my question.  While he did not specifically state the SW could be used in an AC coupled arrangement, I believe it was implied. Since the listing issue, as I understand it, was due to failure to drop out of sell mode in a certain set of circumstances and never had anything to do with the behavior of the inverter in any of its "incoming AC only" settings as far as disconnecting there should not be any question as to its suitability for AC coupling there. The only question would be how they would react and manage backfed AC from a GTI in event of a grid failure. That question is unknown to me and has not been specifically answered yet. Any one have an answer to that?
