handy bob is great, read it a few times,
440ah battery which means 44amps input should be fine on a regular basis, which is about what your panels put out, unless you can adjust your controller it will put out full amps until it is done with bulk charging.
A general rule I have found is that you can have between 1 watt to 2 watts of solar per AH of battery,
Leave at least 12 inches of space above the batteries, 24 inches is better to water them.
