Question: Good day, I have a question regarding ALEKO AR900 Gate Opener: 1) Can be connected to the source of 110v home while having connected my 12v batteries (configured on 24v) on the control board? 2) I have my charge controller LM118, with my solar panel aleko 20W 24v and during the day there is no problem with opening and closing the gate but after arriving in the evening at home 8pm (no problem) and then leave in the morning 7:00 a.m. there is not enough power to open the gate. (I'm using 2 batteries 12v 7ah). 3). I currently have connected the output of the load on the LM118 in the SOLAR port control board AR900 ALEKO Openener Gate. Is this correct ?. Basically my need is intermittent power failure in my house (being outside the home can not enter, the gate is my only entry), so I require an alternative, I thought the solar panel LM118 and batteries would be enough. I think that more capacity is needed in the batteries, but its SOLAR KIT includes two batteries LM125, 5Ah capacity below the batteries I have. I await your response and if I can have 110v power source in my house while the batteries charged with solar panel (as backup) would be great.
Document: This gate opener works great installation 1/2 day they came and before the end of the day it was operational must say quite and works great have a lot of options to use to engage the motor but remote that comes in the package is nice and sturdy and love the protective covering for the buttons when not in use must say a great buy..
I tried to purchase this Aleko AR900 from Amazon, and it dose not indicate weather 13 feed of racks included or not, normally come with it. See Aleco's home page and the package comes with 13 feet racks at $229.00And I requested to the seller weather the racks are included and no response for few days...Looks like they selling good item with poor services.
This thing works great! It was easy to install. I bought a 24v power supply for $40 bucks so there is no dangerous high voltage power connected to it. No electrician required! I also added the remote extender and extra remotes and a wireless keypad. I am very happy with how this works!
Want to verify if the purchased slide gate includes de gear racks or do I have to buy them apart. I just received the motor and according to specs it should include a 13 ft gear racks. Is that correct? Then,  how I buy the gears rack alone?For you info, I need a total of 15 ft gear racks.
I have just received the sliding gate opener in my country Nigeria through my daughter who was on vacation in the USA. I made several enquiries before making the order on the power rating and I also made a note that I needed a 220-240volts. The seller assured me that a step up transformer. Now I have received the order in Nigeria with 110-120 volts, how do I use the gate opener and how do I return the product.Am unhappy.
