I don't know that controller if it is fake MPPT or not. It says high set point is only 13.7v though, which if true is too low except for a float charger.

You would need one for each 240w panel and then the two controllers could go in parallel on one battery bank or one to each bank if you have a split bank.
I will be starting to use mine on a 230w panel later this week for an extended period and will be reporting on how it does.
