@Abdallah Salamah I concur with @Murray van Graan and would simply add that it's important to be certain that you won't be exceeding your battery manufacturer's recommended charge rate at any time; ie, under ideal conditions, with the two controllers named, you could be seeing ~130A of charge into your battery bank, so make sure your bank can safely take that much current at one time.
