How to make a 12v Solar charger system for Caravan, Camping or shed with USB charging

My homemade 12 volt homemade charging system for my caravan, built for just £27 but punching a 10 watt power output. Easy to make, effected and free electricity.

I’m so happy with this simple and cheap system that I’m considering powering all the lamps in the downstairs of my home with the same system.

  1. Hi Ritchie,
    Do you think I could use this system to keep my Ride on mower battery charged up. Could I just leave it connected when the mower is not in use. I great video, the first one I could understand.

  2. Will the solar controlled power up just hook to solar panel? Or need to hook up to both solar and battery then the control will light up?

  3. Hello! I would like to know what type of battery you have charged, how many amps it is and how long it takes to charge it. Thank you

  4. Hi. How long do you think it would take to fully recharged a car battery using the 10w panel. Just trying to work out how much charge would go back in when I'm not using the power. Thanks great vid👍

  5. This is perfect! I've been looking for a decent setup guide on this exact controller. Couple questions if anyone is willing to answer.1. So the usb ports are taking power from the battery, i.e. battery has to have charge right? the controller won't supply power directly from the solar panel. and 2. If you are using this as a standalone, and wanted to use power from the battery directly (not the usb ports), would you then need to connect an inverter?

  6. No that doesn't work like that . That's for 12v for lights and 12v . So it takes 12v off the pannel instead of the battery . Read the instructions

  7. it would be better to set the carvan input to the load terminals on the charge controller this way the battery life is saved from over discharge
