Have you measured space needed for 250w panels?
Cut out a cardboard (or 4) and place them on the roof and see what fits. You need to be 12" to 18"+ from tall items like air-conditioner and open vents. Need 4" to 10" from low items such as closed vents and retracted antenna. Or will this be portable?
45w controller is good for about 700w and even that is above MS recommendations. Unless you will have a large 24v battery....
1 panel just get #10 MC4 wire and pull direct to controller.
2 or 3 panels connect in series and do the same. Amps do not increase in series. Bypass diodes minimize effects of shading.
4 panels is too high of voltage in series so you are stuck with parallel and a combiner box etc. You could go series/parallel if you think shade issues will be minimal. Then you would be back to plug and play with MC4 connectors. Can get #8 with MC4 to carry the 16 amps.
With 1000w are you planning 500+ amp hours of battery? Usually 1 to 2 watts of solar per battery amp hour is way plenty.
