The back of the panel is 15a and I will get the 40a controller. Oh should I get a battery cutoff switch to put by the battery?
Diagram:
Solar panels -> switch -> controller -> breaker -> Pos bus -> battery switch -> battery bank fuse -> battery bank.
Loads -> breaker -> same Pos bus
Inverter -> breaker -> (same Pos bus unless mounted closer to battery).
No need to fuse 2*255W panels. Switch will do. I skipped this switch - solar is always on, and for occasional works I go on the roof and undo one MC4 connector. In series it's enough to disconnect one.
Controller breaker, Pos bus and Loads breaker are all by Midnite Solar and all are installed in the Big Baby box. It's actually a small box but they have one smaller yet. 2 breaker slots remain vacant (one was for planned panels switch), but a smaller "Baby" looked too small for installing both Pos and Neg bus.
Links to MNEPV breakers and insulated Pos and Neg bus are on the same page with Baby.
Battery bank fuse - Battery fuse block, with fuse of required size.
2*255W panels in series with 40A MPPT in Co - maybe, don't know. I would go for 45A.
