In this video, I use a spare 40 amp MPPT solar controller to help cobble a system together to keep my truck batteries topped up. I utilized an existing 100W solar panel I have previously mounted on a toolbox and a 12VDC port in the truck bed.

This mod is desirable since I’m now running multiple surveillance dashcams/cameras in and on the truck while parked. The extra recharge power while the suns out will help keep the truck batteries charged and extend their life.

I can also use this new truck solar system to charge other batteries and even add more solar panels for faster charging up to 40 amps via a portable ground array.
