Charger controller Question

I have swinging gates and have them solar powered. Seems my controller has crapped out and they have sent me 4 Aleko LM118 solar charge controllers and each one when I hook them up I get nothing coming out from the load on the controller. They keep sending me one after another. Today with the controller that I checked out before install I had power coming off the load wires (I used smaller batteries to check it) They were under 24 volts as was the load during testing, that's good. There is 2 lights on the controller 1 light is charge 2 lights is over discharge. Test with power from the load 1 light. Soon as I hooked up at the gate both lights came on. Then when I tested the load I had 0. Those batteries were over 24 volts. I hooked the batteries to the control panel and opened the gate 4 times to get the voltage to drop to see if the load would show volts but got 0. I got these batteries with the 30 watt solar panel. My first thought was the batteries because what started this was at night the gate would stop working SOMETIMES. same during the day sometimes it would work then it would stop. System worked great for the first 6 months
Thank you for your time and trying to help me figure this out. I really need my gate opener

I need a controller that won't screw up in 6 months Any help on a controller that will work with my system.

I have a 30 watt solar and using the 10 watt I got to use as a back up with the system (for electric) so I hooked it up with the 30 w.solar panel and bigger batteries.
Dual swing gates. Lock Master model: LM 902
