I have already been recommended a 40A controller. Is this a calculation that brings you to 30?
Is it better that I go bigger?
I would prefer to go with just the one controller if that's possible as I only have the one array of panels. I don't really see any need for more?
I am unsure yet how to arrange these 3 panels whether in parallel or series but I'll come to that later when I get the components together.
I also am getting quite confused with the numbering. There's a 100/30 and there's 150/30. What's this 100V and 150V and what should this mean to me? Again, is it better to go bigger or is it just a waste of money?
Surely someone really should just put together a "campervan solar in a box" type setup for us part-time noobs
