DIY Remote Gate Opener


Introduction: DIY Remote Gate Opener

About: Engineering Undergrad, Marine Veteran, DIY Everything

After building a Fence we decided we need a gate but shortly after installing it I had to get out in the pouring rain to open it pull the car up get back out and close it. It may be easier to buy a pre made kit but you still have alot of work to do to get it to work. Why not put the parts together yourself and save 500 bucks. Here is how I did it.

First your gate has to be mounted on a sturdy post because the force of the opener is much more than a static gate. I opted to concrete all terminal posts and create corners at the gate area.


  • Linear Actuator ( amazon )
  • Small lead acid Battery
  • Solar Panel ( mine is Harbor Freight HF but now they are much cheaper online)
  • solar charge controller HF or online
  • Remote relay (amazon)
  • winch relay (cheaper online)

Step 1: Power


A few options exist.

  1. Remote location with sun would be best for solar or wind power. 125 feet of direct bury wire will cost as much as the entire solar setup
  2. Near a powered structure an AC to DC converter like the one powering you router would be sufficient.

Step 2: Solar Power Source

My set up uses some old and new components. The cost with links is listed on the video.

The 15 watt panel feeds the controller charging the battery (easy part)

The remote relay is wired in to the winch relay to create a reversing circuit (test before you unplug anything and label the wires.)

The battery is the same cost as a gate battery but is really the cheapest lawn mower battery at tractor supply (with more amp hours than the little gate one)

Step 3: Angles

Getting the angles right is different every time. I used old bed frame angle iron to make a triangle to mount to the gate. The actuator came with the small mount but is not nearly enough leverage to move the gate, especially in a strong wind.

Mount the actuator to the hinge post and the to the gate paying attention to the stopping points

Step 4: Reinforce Your Gate

I used the same angle iron as before on an entire span of the gate and have since added U bolts along the span

Step 5: Test and Enjoy

Once you have everything mounted and wired up you should be able to move the mounts around to get your desired stopping angle. test the gate from full open to full close. ( starting with a charged battery helps )

Enjoy not having to get out in the rain to open an close the gate every time you come home


If your using the same remote as I am do not forget to turn the power switch off.

There is no safety... children should not be near the gate when in operation

Running the White antenna wire up and or out of the box is required to reach full range.

12 volt is very safe, but if you are using 120 from the house then all electrical standards should be followed (most low volt systems are unregulated)

    Do you have a list of the parts"
    what is the throw of the actuator?
