  • What else do I need?

    I bought a fan that uses 22 watts. Unsure what setting, I'm guessing low which is what I use.

    To power it I bought a 125 watt solar panel sheet, charge controller, and a 102 ah deep cycle battery. I went heavy with the battery as I plan to keep it for a long time and eventually power an Engel fridge.

    So what next? How does the battery connect to the fan? I'm totally new to this. Thanks for any help.

    Alright after doing a bit of research I can't really find what I'm looking for. I wanted a setup that worked without being connected to a car.

    A solar panel connected to a charge controller connected to a deep cycle battery connected to a 22 watt rechargeable fan to use inside a tent while I sleep during the day.

    I'm sure it's possible, but all searches lead to car setups. Looks like I'll have to do it that way for now, and seems I have bought all I need, just have to learn how to install it properly.

      What is it that you want to do ? Run a fan in the day, or at night ?
      125 w panel should be able to harvest enough power for a fan for several hours a night. You would us a 12V deep cycle marine battery, not a car battery.

        Run it for 8 hours during the day. I'm a truck driver doing night shift, bought a tent so I could save money faster and sleep in it 2 nights a week. It's summer in Australia and is hot in the day.

        Also I bought this battery because in 6 months I'll buy a 4wd and caravan, this battery will be powering a fridge.

          OK, so since the Panel will be powering the fan, while the sun is out, the car battery may be OK, and won't get deeply cycled.

          However when you connect a car battery to power a fridge, you will be deeply discharging it, and will in less than 100 cycles/days, see the battery go bad.

            Right, seems I just wasted over $300.. Marine battery you say?

            This is what I bought; https://www.centurybatteries.com.au/...tery/n70t/info

            Thanks for the help mate. Got everything sorted now, but will need to research more on a battery suitable for running a fridge.

              Well, thats a flooded deep cycle battery (You add distilled water monthly if needed) and should last you 4-5 years. Then you need the specs to see if it is large enough to run your fridge. You will likely need more panel for the fridge
