Man that is some great info.... I had no idea that the temp made that much difference in voltage from the panels..... I think I will be just fine with the set up I have right now all year round...... With the panels angled like they are in the winter I really doubt the voltage will be much difference than it is right now but we shall see..... Like I've said before, This crap isn't easy as you might think if you use it like it is intended......... Many thanks for your help....... |

The answer to my question is NONE... The 4 6v batteries that I had to start with, with the 5 100w panels and a 40a CC... For it to work correctly...
When I added the 2 additional batteries the 5 100w panels I had they weren't enough to keep them charged fully with the power I was using 24/7.. So I added 3 more panels for a total of 8 100w.. Now it's working perfectly with my 40a CC from Renogy.....
Sometimes you need to take a day and read all you can about solar yourself.....
