How many watts is the solar panel you have?

If the controller for the gate has solar marked terminals, you're most likely all set. Unless you have a huge solar panel putting out more watts than that controller is rated.

If no existing solar terminals you probably want to buy a solar battery charge controller and wire it up directly to the battery(s).

Thanks for the link, that looks like what I need; provided there isn't already such a circuit within the unit, which is a question I am trying to answer.

I looked quickly at Mighty Mule site and quickly at a user manual on one unit.

Looks like their control panels may or may not include connections for solar - some do, some dont. And if your's does have solar connections they apparently are only rated for a solar panel, or group of panels, up to 30 watts max.

I didnt spend much time looking and the model I looked at may not be identical to yours, so take what I say with a grain of salt about those contacts until you look in your manual & control panel.

Hello,

Question: I have the Mighty Mule Dual Gate Opener (FM 402). I purchased this solar panel (http://www.amazon.com/Instapark%C2%AE-Black-Mono-crystalline-Charge-Controller/dp/B005LR9IOG/ref=sr_1_4?ie=UTF8&qid=1384289004&sr=8-4&keywords=INSTAPARK+10W+SOLAR+PANEL) instead of the mighty mule solar panel. It comes with a charge controller. Do I need to hook up the charge controller of the instapark solar panel to the mighty mule control panel or is that redundant? Would I just connect the wires from the instapark solar panel directly into the two terminals of the mighty mule control panel? thanks.
