Greatly appreciate folks input, knowledge and suggestions.

In regards to the array, the proposed addition of a pair of 330w panels would be wired in series and have a value of Voc/V: 39.85 and the existing 200w panel has a value of Voc/V: 40.12. Would a single MPPT controller of 100/50 safely handle the input of the array wired series / parallel on the existing 10awg wiring? If I understand correctly, the 10awg wiring is good for 30 amps - with associated line loss of course. I plugged the following into an online calculator. Am I out in left field here or am I on the right track?
