01/18/2024 review update:Now that a new year is here, the tracker and wind speed indicator have had time to work. I will start with the controller that is connected to the main post is water proof, and as seen from the picture supplied is attached different from directions. True the directions do not show the unit (tracker controller) is already prewired, with the exception of the wind indicator. My controller was not programmer by me until much later, and it was found that it used the default programs to track the sun. The newest "solar tracking controller" being prewired is nice to know that the case does not need to be opened which makes it easy to connect the activators N,S and E,W. If I want to turn the unit off a simple on/off switch was installed from the unit battery. Testing the “wind speed sensor” did not send the tracker to rest position with light wind of 20 mph.more later...10/25/2024 review update:Here we are getting to the end of the hurricane season in Florida. Hopefully the last hurricane (Milton) witched moved across central Florida from the gulf and had land fall as a cat 3 hurricane. Here in the Tampa bay area we had some high winds, The base were the 8 hold down bolts had no damage nothing bent, but need to reset it back on the platform. The control unit is still water tight, and the solar panels came through fine, withe the exception of one that hit the ground and cracked. The whole base unit is solidly built and weathered the storm nicely. the activators were pulled lose and some of the rails that the panels were connected to were bent. After adverse conditions the tracking system showed it was NOT cheap constructed and solid.Have been following this solar tracker for some time on Amazon and finally bought one on prime-day. Included is a picture of the solar tracker (completed). I could see right away after receiving it that the tracker runs independent of the solar panels. One simple reason, it runs on its own battery. A lithium deep cycle 6-amp battery is a good step in the right direction to test the activators for N, S, E, W,. during and after completion of tracker. I took my time building the tracker and a few weeks later when almost completed the controller screen went blank; my first thought was there was something wrong with controller, but what I did was put the battery on (smart diehard) charger for 5 minutes and got my screen back.I realize this review is for the tracker only, but what about solar power, do we just hook up solar to the power box and use less electricity? There is something called off-grid and on-grid. I can hook my toaster to my 2 kilo-watt battery with (inverter built in for AC as part of unit) for a minute or two and not see much reduction in battery power percentage drop, this would be off-grid power would it not? Then the sun through the solar panels on the tracker, keeps the battery charged.A good place to start a review is with the base – in this case the platform and main pole. The platform has four 2 ft 4x4s with 24” ground anchors which makes the platform very sturdy. The main pole has been improved at the base with 8 expansion bolts and now 8 panels 90-degree welded panels, to support the pole and base that the bolts connect. The written directions were very clear up to and through the connection of the long and short activators. When testing directions N, S, E, W, the west button was pushed, and the direction of the tracker moved East. The D-Rod needed to be repositioned, that is, connected to the long activator. Doing so, this switched the direction, so now west goes in west direction.Also of interest, there are some very good videos on the Amazon “ECO-WORTHY Solar Panel Dual Axis Tracking System” listing, that have recently been added. So it seems the company has made some good improvements in both documentation and equipment. To list one document improvement an online video has troubleshooting of controller programs as well!!The design of the tracker is quite good: with connecting the channel steel to the E-rod with 6 bolts for stability. But there is one problem: the “center solar panel“ middle clamps are stopped by the E-Rod for a secure hold down (bolts to long), A fix could be using a handful of extra washers.Summary: The main pole being connected to the wood platform is very stable. If the wood platform can stand high winds, the metal base and pole connected should be equally secure. The power for the tracker has a max amp output of 15 amps, I added a second 12volt 6amp battery in parallel connection for a total of 12 amps for backup of the second activator. I was thinking about hooking up a car battery just to test electronics; good thing I did not; that would have burnt out most of the electronics. With the improvements and added online documentation the 2023 solar tracker is coming into focus. I highly recommend this product! (Note: this tracker was installed in central Florida where high winds are the norm during the season).

I had five stationary 100W panels powering my Chicken Coop (lights and fans), Gazebo (lights), and Pathway lighting. These are all located in a densely wooded area, so my stationary panels only received a couple of hours of sunlight a day, causing my two 100AH batteries to often dip below 11.5V. I decided to try this tracker, knowing it might struggle to track the sun given all the shade.I'm no solar scientist, and I've only had it in place for a month, but so far, there is a definitive increase in my solar collection. I've observed it tracking quite well, even with the many pockets of shade. Overall, I've been pleasantly surprised and am giving it 5 stars despite my minor criticisms below and the short amount of time it's been in use.Out of the box, it seemed sturdy and well-made. Everything fit together perfectly, and the assembly instructions were good. I painted the parts prior to assembly to blend in better with the surroundings. I customized the controller mounting as it didn't seem very well protected from the elements, and the vertical mounting seemed odd. I also fabricated a different mount for the sun sensor. The original mount and placement are likely fine for most, but because of my shade issues, I'm experimenting to find the best placement (and controller settings) to avoid having the unit struggle to find the sun. I purchased the Eco-Worthy combiner box separately, mostly for surge protection and to help with the cabling, but in retrospect I probably could have done without it. I do wish there was some sort of channeling or hardware guides for all the cables. At a minimum, some guidance on best practice cable routing and leeway for movement would have been helpful.For me, the biggest struggle was with the controller settings, which are critical but cryptic and poorly explained in the provided instruction guide. Luckily, there are some great customer YouTube videos to help with that, because there's a 100% chance that most, if not all, of these settings will need to be adjusted from their defaults to meet your specific setup/location. I ended up putting my interpretation of the settings in google sheets (pictured) just so I could track my tweaks and hopefully fine tune things for optimal performance.

works as advertised. Unistrut blue Fastners were wrong size.

Works great exceeds my power needs definitely a great tracker. Some say the wind sensor doesn't work but it does just have to adjust the setting if you want it to work well.Been using for about 3 to 4 months only issue is the pivot bolt came loose and the whole array just came down last night breaking 2 panels and bending the actuators. Maybe 300 in damage but not the end of the world, parts are maybe 4 days out and I'll have it back up. Don't be scared just tighten your bolts now and then and maybe drill out the end of the pivot bolt for a cotter pin and you will be fine.Things happen is what it is but when it's working with 10 100watt panels I can catch at least 9 kwh of power off it. Typically 2.5 as I don't use much power and my controller doesn't track power caught but not used. Running my ac all day I have tracked up to 10kwh for the day

I had a problem with the controller on the solar tracker.Originally I just needed a mount for my solar panels, so this being a solar tracker was really just a bonus. I called customer service, but while I was on hold I thought I could live without the sun tracking feature and hung up before anyone picked up the call.After a while I realized I was wasting Sunshine and money without using the tracker to the best of its abilityI contacted customer service again and was directed to a rep named Dante. Hoping I hadn't waited too long before contacting them but Dante was very understanding and helped solve my problem. So now I'm tracking sunshine again like a pro.I highly recommend getting the solar tracker and the customer service is top shelf.
