CMTP02 MPPT Solar Charge Controller, 30 Amp 12/24 Volt Display

Model number CMTP02. I picked it up on geek.com or wish.com, I can't remember which website. It cost $11 usd. The reason I made this video is because of the directions that came with this unit was very difficult to understand so I made this video after looking at this solar controller a couple of times over a couple of days to where I figured out what was going on with it. It automatically switches from 12 to 24 volts. I have a 24 volt 310 watt solar panel going into the unit and I charged 12 volt batteries and I've also charge 24 volt batteries automatically without doing anything to the charge controller. I don't use the charge controller continuously I use it on occasion but I've had it for 5 months and it works fine.
