18650 battery pack for solar
#1
Hello to all!

I intend to make battery pack for mu off grid solar system. 
I harvest 700-800 batterys and testing is in progress. Most of them are 2000-2300 mAh. I use Lito kala tester and charger. 
My batter need to be 12 or 24V. What is better for build, and what serial I should do? I see somewhere that for 24V I need 7s. 

7x4.2 is 29V. My solar panels give me 30V so I think that I will not get full charge? 
On another hand for 12V pack will give me in 4s 16.8V.. I am confused. Maybe best way to make 3s? 

What I have is that I make good and safe battery pack as my loog cabin is from wood. I dont want fire there.

Just to add, all my consumers are on 12V and my solar system is 24V where I use step down 24 to 12V.
I have 4x5 trays for batteries.
