I have been through so many of the boards here (searched and read through) looking for some similarity to my situation. My property is vacant months at a time. There is no power to a distant part of it. I want to set up some type of Solar security system that entails 2) 12v field cams (use 8-1.5VBatteries, a 12Vdc CCTV security cam (that I want to add a TX to go wireless), 2) 36 light LED Security Lights (will need to modify) they are 3.2Vdc ea. I have a 100W Solar panel and a 10amp charge controller and a 18AH battery ( I am in FL so hoping this will be enough) None of the items hooked up to it is a major drain.
My question is really about the 2) LED Security Lights as they are such low voltage
and have their own Battery capacity 600 mAh ea light , ( I want to direct line in)
Battery type Li-ion
Battery voltage (volts) 3
DC Volts 3.2
Thought of using these items to regulate Current/Voltage and add a Dusk-to Dawn Feature
DC-DC LM2596 Step-down Adjustable Power Supply Module CC-CV LED Driver
and
HIGHROCK Ac Dc 12v 10a Auto on Off Photocell Light Switch Photoswitch Light Sensor Switch
(The lights have only ON or OFF switch Hence the dusk to dawn feature)

Trying to get a grasp on some of the challenges before I get there!
Any thoughts/ideas on how best to tie these into the 12Vdc line??
Or anything else I should be concerned about??
(I'm more mechanically inclined than electrically But I do try no matter how challenging!)
Thanks for any help you can give!
PS: I'm not ready to build my own pcbs just yet LOL!
