I can see the two inverter breakers on the right. I am wondering what the two breakers on the left are. I'm thinking one of these is an 80 amp breaker for the output of the MX60. The other one is probably a PV input breaker of unknown rating. I would need to change these to accommodate the new charge controller. The Midnite Hawk's Bay 90 requires a 125A output breaker. Does anyone know if there is an Outback breaker of this physical size and 125A rating to plug into this DC FlexWare enclosure? For the PV input, I should be able to get whatever breaker is required for this single string of PV. </div><div dir="auto"><br></div><div dir="auto">I'm all ears if there is an easier way to go about this with approximately 3,600W of new PV.</div><div dir="auto"><br></div><div dir="auto">Thanks in advance!</div><div dir="auto"><br></div><div dir="auto">Jason Szumlanski </div><div dir="auto">Florida Solar Design Group </div></div>
