Seeing as we are talking controllers

I have two identical 90W panels, solid ones. I currently have a BZ Products MPPT250 Solar Controller.

I just added 4 flexible panels, two 30W and two 50W:

Should I get a second controller? If so, any recommendations? I dread to bring up the series vs parallel wars , but any suggestions on wiring?

Great info MS, thanks.

So you are saying that I should have three controllers total? Each on controlling an identical pair in parallel?

How do I go from those three controllers to the batteries?

In all honesty I would suggest using what you have. The outlay in expense for a few % gain in solar performance is really tail chasing at this point.

Oh, so just stick all six panels into the BZ MPPT250?

I think I am losing the plot

The bz is part of the current set up. Right now I have the two larger 90W panels going to the bz250.

I have bought the four smaller panels, but no controller as yet.
