I’ll spare you the details of how we got here (this started as half this size bt we doubled and enlarged to micrgrid support instead of single ranch dwelling.)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Because of the increases, the ability to network all together with hubs is not possible. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>It seemed as if the FM80s were not producing as much as they could. I’ve checked the charging parameters and feel good about those. All voltages are calibrated across the FM80s as well as the Mate 3. The Mate 3 is connected to the eight inverters only. The FM80s are not networked together; I was concerned about that until I read an earlier post here. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Yesterday, I left with an impression that my challenge might be the inverters not selling to their maximum potential. It seemed like they certainly had more voltage “space” before they hit the lower threshold for sell voltage but the inverters just were not making as much I expected them to make.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Only indication to give you is that the inverters, as seen on the Mate 3, would cycle up to a max about 11kw of selling back to the grid and then return back to 4KW of selling (while meeting minimal household loads on during home reconstruction. It would hit this peak and cycle down before it hit the sell voltage.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Each port for each inverter is set for 50A. The charger for each port is set for 30A (even though to be quite honest I just do not know why/how the charger must be on for a grid-tied system with PV charging…)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Any thoughts or recommendations? I waited for a return call form Outback but nothing yet and know somebody here will have some ideas.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><img width=294 height=116 style='width:3.0625in;height:1.2083in' id="Picture_x0020_1" src="cid:image003.png@01D62E81.5B1DD930"><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
