The system currently does not have any disconnects on the PV side. There are fuses in the combiner boxes on the array, but no disconnects inside at the charge controller. So adding 3 charge controllers, and now needing to add GFDI, means a box of some kind needs to be added to house these breakers. <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Outbacks GFPs and panel mount breakers will work, but what is the best mounting solution for these? One DC Flexware enclosure? It will of course allow for all the DC OCPD and allow for the landing of the output of the charge controllers.
