I run a facebook group dedicated to teaching solar. Typically i advice against mixing solar panels because most of the time the efficiency losses are to high. So i will advice multiple charge controllers.

However this diagram was posted on my Facebook group. (This is NOT my design).

If you follow the math to it’s conclusion I get 98.44% efficiency.

However if you look closely at the diagram you will see he has mixed configuration creating sort of a 2P/2S/2P configuration.

My question is will this work. He has basically done one parallel string (2P) and then a series/parallel string (2S/2P). Then taken all that and put those in parallel as well.

Will this work? Theoretically the math comes out but can the Smartsolar 150/70 understand what is happening here and look at it as just a 2P config or will it freak out?

Thanks for your help.
