Thanks for your replies.
So these are the panels I’m looking at –> Solareon - REC 460W Alpha Pure-RX Single Glass Bifacial All Black Solar Panel
(460w x 4)÷48 = 38.33A. I’m assuming I could then use a 150/45, 2S2P connected? [like this person has done]
If I use the MPPT sizing calculator, it’s says I need a SmartSolar MPPT 150/70 Tr VE.Can
