    Just installed this today, the directions for the controller not that good, but found several great YouTube videos to program the controller. I have it hooked to my travel trailer deep cycle battery, on a overcast day was stilling getting 12.9 volts from solar panel to charge the battery facing true south. Wasn’t sure what to expect from this for $33, but it’s doing a great job, and I can always upgrade to a bigger solar panel with this controller. Highly recommend this unit. I looked at several solar battery tenders, and this is by far the best deal. 5/30/20 On 5/29 went to take camper out, had controller set to maintain 13.2 on battery, it’s was on 13.2 so this setup works well. Most important thing to do is program controller correctly. Solar panel has been left out in rain but I setup the controller in my battery box. If you search the controller on YouTube you’ll have several helpful videos to help you program it. For $33 I absolutely love this unit, no more dead battery on my travel trailer, I bought this because I just bought a new deep cycle battery and their not cheap. Very happy, would buy again.
