3 x 4 Configuration

1st step, you need to connect 3 panels in in series i.e connect the +ve of the first panel to the -ve of the second panel and then connect the +ive of the second panel to the -ve of the third panel.
2nd step, repeat the first step for panel 4, 5 and 6.
3rd step, repeat the first step for panel 7,8 and 9.
4th step, repeat the first step for panel 10, 11 and 14.
Now you have 4 strings connected in series.
5th step, connect all the -ve in each sting together and then connect all the +ve in each string together. You now have just 2 cables one +ve cable and one -ve cable going into the PV terminals of your MPPT charge controller.

Please see the attached diagram and let me know if you have questions.

thanks a lot , you are a life saver. I get the gist now. will keep you updated when through. you be the man...

Since you have an MPPT CC, you should arrange your panels in a 3 x 4 configuration
i.e 3 panels in series and 4 panels in parallel.
If the distance from you panels to your charge controller is far, then you may consider a 4 x 3 configuration.
Let us know the outcome this setup.

thanks for the help. in short the 3 panels in series will give 72 v, I understand that, but the remaining 9 panels do I parallel them all. pls bear I am no engineer guru, can explain a bit on (3×4 configuration). thanks.

you guys are great . have been silently learning from the gurus in house. now I have finally plunged in. house I have 12 poly panels 24v 280watts each, a episolar charge controller mmppt 60amps, my system is 48v 200ah. my question what is the best solar panel arrangement to maximise or give the best out of my panels. pls appreciate assistance want to get this aspect correct b4 moving forward....
