We are doing a ton of work, including adding a 4 kW solar array with Classic 150 charge controller. I am trying to figure out how to handle the GFP.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>For the Classic, I need a 90 or 100 A output breaker minimum. 80 A is not an option. The OutBack dual GFP is 80 A, and so it not an option.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Is there a 100 A GFP breaker assembly I have just never seen? Is there a way to use the Classic’s GFP to run an external relay via AUX (to trip the FM60 output breaker at the same time)?
