I think he's set now isn't he . His question has been answered and its his choice? There is 3 pages of discussion.
There are only 2 choices really if he wants to use all 10 panels and now it is a matter of wiring .
I will say though that the 5 parallel idea presents a challenge getting all the panels connectors joined to the 5 way combiner and then a suitable solar wire to the charger with current carrying capacity. Also there will be wires coming out of the array all over the place which will need suitable securing points. Definitely not the way I would go.
