Question: does it come with a solar panel??
Document: Works very well. The control panel is well organized. Note that the battery is not included. The wire for the A/C power adaptor is too short be be of any use and I ended up buying the solar panel.
They are much more dependable. They have a 10yr warrenty. I told my friend I would not help him if he didn't spend the extra money for this system. He finally agreed. I knew how mad he would be if it was not trouble free. You put in a gate opener for convience. If you haved to fool with them to keep them working it's kinda self defeating. I haven't use te solar option yet but since these run on 12v not 24v I'm sure it would work.
USAutomatic Sentry 300D Gate opener is horrible! It has never worked right even with professional installation. I returned many openers. US Automatic Opener even acknowledged that they had a know problem. SO far I have over $1500 into opening two light gates and they still don't work right!!!!! Horrible product!
It is well made and easy to install. There are plenty of options in the use of this gate opener. The quality in material and design is outstanding. The only part I would change is where the actuator attaches to the gate post, I would use a pin like the one used on the gate attachment point. I did not like the bolt and nut method in that I had to use Lock Tight to make sure the nut would not back off.
If a gust hits the gate while the motor is running assisting it. It can run a bit too far. If it goes just far enough that the limit reopens when you actuate the gate again it try's to keep running the same direction jamming the motor. A condition not easily diagnosed by a homeowner. Rain seaps into them. These US made openers are strong, leak free (so far). With the limits adjust by pots inside the control box they run the proper direction every time.
I worked 10yr as a garage door installer. Installing door and gate openers frequently. I have installed 4 of the imported gate opener systems for friends etc. This was the second install of this brand. This time for a dual gate system and by my recommendation. This brand is nearly double the cost of the imports. It's worth 4x literally. The housings are sealed, all metal, pre-wired. The control box is simple to adjust and understand, gate limits are adjusted inside the control box.
I soldered and heat shrink wraped the connections. I cut the wire from the motor at about 8" so the soldered connection would never hit the ground. Even though it was well sealed. The control box end I cut the wires at 6" from  the plug then used single closed end crimps the make the connections. This kept the joints inside the control box. I also used some rtv sealant on the control box mounts. Most of the problems I fixed over 10yrs from all brands were all moisture related.
Do a little extra on the install and you won't have to do it twice.
Answer: yes
