Another good call on your part TorC. The grid power 50A, single pole breaker is to accommodate future growth. This drawing is corrected for both circuit breaker amperage and wire size.If your grid input is really a 50A breaker, I'd recheck that wire. IIRC, that should be 8 or even 6 for 50A.
My DIY assembly instructions remind me to use 6 awg from AC Main to disconnect, but I must use 8 awg from disconnect to controller AC IN due to wire size limitations on the controller.
Here are 2 excerpts from my DIY manual.
1) "AC Main Panel OUT to AC Disconnect IN - Southwire, Romex NM-B, 6/2 with Ground; Quantity 1, Length
2) "AC Disconnect OUT to Controller AC IN - WindyNation, CBL-CSBL/RD-08, 8 awg, red and black; Quantity 3 (one wire taped green), Length 2', Black, black (taped white), black (taped green), Stranded, 125°C, 55 Amp Rated. Circuit Breaker Torque 40 In/Lb."
If your inverter can pass the whole of that through, then you
shouldmust use at least the same wire for the inverter output.
My AIO controller Max bypass input current is limited to 40 Amps. I believe we are both referring to the same same values.
Wire and fuse sizes FIXED in drawing 499.
