24V Panels and 12V Battery

[Bhooralshah786]

I have 24V suntech stp180s-24ad 180watts 2 panels total 360watts

And 12V 200AH flooded one battery

No controller

Please guide me Its work with 12V battery or not and which controller for best charge fast and Maintenance battery life.

It will work with an MPPT controller.

Depending on battery size (AH) and type, 360W may be a bit too much for one battery.

Welcome !

You will need a MPPT controller to "match" the 24V panel to the battery. The best controller for this may be the Rogue

The 30A metered Rogue http://www.roguepowertech.com/products/mpt3024.htm Sweet as long as you do not exceed the 60V max input .

The next step is the Mornignstar, then Outback, Xantrex, and Midnight Classic controllers.

Yes you can. Buy an MPPT controller. It will drop the 24V down to 12V.
