grab that panel mate... you don't need a converter.
any decent MPPT solar reg will take 60 to 75 VDC input and "convert" it to the system volatage IE 12 or 24 (in your case 12).
I like Victron but there are others... either of these would do (30 or 50) https://www.victronenergy.com/solar-...rs/mppt-100-30
