12 volt panels to a 24 volt controller how to wire
i have 12 120 watt 12 volt panels , and a 24 volt charge controller , and a 24 volt inverter , 16, 6 volt batteries i series the batteries to 24 v . do i series the panels 2x2 then parallel them to the charge controll ?

Don,
Could you tell me the model #'s of the modules and the charge controller that you have?
I would be happy to make a wiring recommendation for you and double check that it works for your charger.
i need to elaborate some ,, i have had this system for going on 16 years now and i sufferd a lightning strike that totaly blew up 4 panels , and took out one charge controller , in repairing the system " as i have a spare inverter i" i thought i would make two systems . here is what i have and have done.
40 - kryocera 120w 12v panels
3 - trace c-60 charge controllers 12/24 volt
1 - 12 wind charger
1- trace 12volt inverter
1- trace 24volt inverter
with the damage to the panels and controller and 8 batteries and being off grid i had to get fixed fast .
so now the 12 volt system is on and running ,
20 batteries , 24 panels , 2 charge controllers , wind and inverter all is working .
i wanted to take the 16 batteries, 12 panels , and the 24volt inverter and make a second system 4 panels were fryed . as seemed the controller.
when seriesing the panels i would get 0 voltage , turns out more panels were burnt from the lightning then i thought ,, so i cut into the back and found the burnt traces, and silver solderd them down 1 module each ,,, now they out put 33volts each in series ,, the controller seems good when jumperd from 12volt to 24 volt , so all in all i have the two systems running now .
so in having two systems of different voltage , i split the breaker box to the house , so as not to collide the 2 inverters ,
i know this is a rig job and it has been very frustrating , i hope i have done the right thing in all this ,,, any suggestions will be greatly appreciated.
Don, sorry to hear about the lightning strike. Sounds like it was a direct hit on your array. I do not see anything problematic in your new approach and glad you've got yourself back online. Isolating the two was probably a good idea as you are now feeding two separate battery banks. Have you installed some surge protection devices to your repaired equipment? If not, it might be a good precaution to have a few installed. They say lightning doesn't strike twice in the same place but I would not want to risk having that happen to you again.
