Can I use this in a 12v system I’m making,

320W 24V x 2 Monocrystalline Renogy. I’ve read yes and no. Please help! Thanks for any help. Newbie here.​

Please post a picture of the tag on the back of the panel.
Also please post a product link for your solar charge controller.
That way we can see if they will work together.
 
Thanks!

The open circuit voltage on that panel is 40.1 volts.
We need more detail on the solar charge controller.
Also the pictures are small and very difficult for me to read.
 
I think this will help. Thanks for helping me.

Yes, you can use those panels for a 12v system. The VoC on the panels gives you the choice of parallel or series, whichever works best for you. You'll be limited to 780w of panel input on a 12v system though so 2 panels is about all you can use without planning angles and overpaneling.

Is This the Link to the product?
 
From @Rednecktek 's link (DC18V - DC150V) should be fine in series or parralel.
Series is preferred unless you will have shading issues.
 
Assuming you have the SF4865, yes. Those will work.

Because you are running a 12v system, I would recommend putting the two panels in parallel so as to not exceed the recommended 60v parameter. Though, the system is rated to accept up to 150v if necessary.
