Hi guys I hope you are doing very well.
Before I post once my problem and you guys gave me advice and I able to solve my problem thanks a lot for that and hope you did same this time as well thanks
I'm using 150w*4 12v solar array
Conected 2+2 =24v

Gel Battery 150Ah*4, 12v ( http://www.narada-ap.com/index.php/download_file/view/269/95/ )
But using as a 24v bank

And my charge controller ( http://solarsystemsphilippines.com/wp-content/uploads/2012/08/VS3024Nmanual.pdf )

In my area full sunshine time is around 7,8 hr
And now days temperature is 35C'
So now my question is
Where can I set

Charging and Discharging Parameters Setting. you can find on page 21.
Pls have a look battery and CC links page and give me your advice
Thanks a lot.

    Your links need to be fixed... The "..." ellipses are also in the links themselves. They were shortened by a website and when you copy and pasted, you got the shortened links.

    I am not sure of your questions... It looks like you have a very nice GEL battery and a standard PWM controller. If you set it for GEL, the defaults are pretty close to what your battery asks for. There is a bit of different naming on the controller vs what we usually use here (I think):

    Boost=Absorb charging voltage set point

    The battery gives "per cell" voltages... For a 24 volt battery bank, the charging voltage set point would be:

    2.4 volts * 12 cells in series = 28.8 volts at 25C charging voltage

    And so on... GEL batteries do not like to be over charged, so once you set the charging voltage and float voltage--You should use a good volt meter and make sure that these voltages are not exceeded (on days below 25C, the voltages may increase a bit -- cold batteries need slightly higher charging voltages).
