Does anyone know of an efficient inverter that would work out well to AC couple with a pair of Outbacks on an 1800 Watt array. The 90% efficiency range is what I've been seeing. The new high frequency SMA inverters look good, but last I heard were still tied up at UL.

However, I am considering Enphase for a large res retrofit which will recieve CSI funding. I am obligated to provide my customer equipment that will be warrantied by the manufacture for 10 years. I have to have certainty NOW that the warranty will be honored in the application. I can not base the fulfillment of my contractual obligations on the passing whim of the support technician of the day. My project involves placing the Enphase below the ATS on a gen back up system, an application which Ehphase will not warrant in writing. So the question is, can I do the project at all? All you folks who are putting Enphase on the load side of grid-tied, battery based inverters need to ask yourself the same question. It appears that Nick already has his answer.

If the inverter is truly failed, I am sure that you won't have an issue. But since they are so reliable, that probably won't happen anyway. However, if you were to install them in an ''off-grid" application, you can't expect them to guarantee the performance, which is what a 'written' guarantee implies. I bet SMA won't provide a written guarantee that they will perform when coupled to an FX inverter, either.
