The pair of 280s will max out that controller and work beautifully.
Parallel or series is about the same. Parallel will have slight advantage in conversion from 30 volts to 14 volts vs the series 60 volts to 14 volts. Series is easier to wire and is slightly more efficient through the same size wire. Virtually the same power either way.
Controller converts the watts to the same amps and volts as needed by the battery in either configuration of parallel or series. Partial shade is a killer and could be better or worse with each method depending on actual conditions. I call the shade issue even in the long run.
I went series with mine as the wiring is easier and I like easier.
The 560w might be technically more than the max wattage however you will be lucky to actually get that much wattage in general conditions. MPPT controller will limit power to the rated max and will perform just fine. Critical is to not go over max 150 input volts and you are not even close.
