And thanks Bob-O for posting their tech support number. </div><div>Recently I had to get this number from AEE since it is not listed in the Fronius manuals. </div><div>A new installation with a pair of 11.4-3 phase Delta inverters refused to come up and detect the grid. A call to Barry at tech support solved the problem-- press the Menu button 5 times and enter a secret code number. This was of course undocumented in their manual. No reason for this kind of opaque secrecy. </div><div>But is there any other option for 240 VAC 3-phase Delta inverters? (Except for Sunny Tower with single phase inverters.) I'm about to buy some more for another new installation with the same service....<br></div><div>Thanks</div><div>Don Barch</div><div>Energy Solar<br></div></span></body></html>
