I am getting confused using both the online Sizing Calculator and Excel. I have four (4) panels with the following specifications.

325 Watts

Voc = 36

Vmpp = 30

Isc = 11.88

Impp = 10.82

Can anyone help me determine which controller(s) I need and in which configuration I need to wire the panels? I have 430Ah of 12V AGM batteries to connect. Thanks.
