Dual Axis Solar Tracker System

I do love my trackers. They work well. I have made some modifications to ensure safety and stability.

1) I'm in Michigan where it gets under 0F degrees in the winter. So, charging batteries outside was not an option. Using an power AC to DC power supply connected to my inverter and run a line at 48v to a DC-DC converter at the tracker to step down to 12v - Works well in my use case.
2) I purchased 3 heavily reinforced Unistrut and used them to mount my panels in a standard 8 panel configuration (200w 10BB bifacials) - The Unistrut included is not the heavy stuff, so it bends easy.
3) I mounted everything into a metal junction box because of weather here; I had my first controller die (screen couldn't handle the windchill here)
4) flip the actuator mounting bracket that connects to the upper swing bar for East/West, so the west tilt does not go vertical. My Actuator literally snapped. This is a major design flaw. So, watch it.. not safe.
5) Added Bushings to the east/west lower mount point that connects to the N/S arm. This is important per number 4, when the actuator broke, it's only surface mounted and bent the metal it was mounted too. A simple through bolt and bushing salved this.
6) Because of number 4, I replaced my actuators with more heavy-duty ones from Progressive Automation. Eco-Worthy. Please at least provide an option for us to purchase more heavy-duty actuators. The ones included are iffy at best.

Eco-Worthy.. Please consider better actuators, maybe an upgrade kit that allows more panels that has re-enforced Unistrut as in my photos, heavy-duty actuators, and please re-enforce the lower North/South arm where the East/West actuator attaches with through bolts and bushings. plastic insert bushings would be fine... anything other than surface mounting there would be great!

I decided to buy this tracker due to our limited solar hours up here in northern ny. The price was very affordable and just the right size for a small backyard array. The tracker arrived well packaged with no damage, assembly was quick and straightforward. We installed 6 ecoworthy 195w bifacial panels and did the required programming.
It works very well! As soon as the sun pops over the trees it faithfully turns the array towards the sun. Tracks the sun very well throughout the day, and returns to its low light position every night. Wind protection function works as it should. It really does get us the most out of our system! I have only 2 suggestions for ecoworthy to improve this tracker, 1. Add another set of mounting holes for the north/south actuator for those of us way up north. This would allow a bit more southern tilt to get the best angle to the sun in winter. 2. We noticed the tracker was tracking a bit ahead of the sun at first. The thin metal mount for the sunlight sensor is easily deformed when tightening the mount bolt, which was causing the error. A better mount, or better yet, an adjustable mount would allow fine tuning the tracking! All together this is a best value set up for those of us with limited sun hrs or obstructions that want to get the most out of our panels! The quality is good, very sturdy! I would like to try the single axis tracker on my next small array!

This is my 3rd Solar tracker. I can say i almost love them. They could use a couple improvements. 1st. The controller needs updated. I would say it's outdated in today's world. 2nd. It needs beefed up a little so it can hold bigger wattage panels. The axes wobble a great deal. 3rd it needs a locking arm for extreme winds. I designed my own so I'm sure the engineers could desghn somthing better than mine. But except those few items I really have no complaints.

The tracker system will do a good job for the person buying it. The controllers act up now and than. I bought six trackers and replaced one controller so far.

Installed 2 out of 4 so far. Being a contractor answered most questions I asked of the system. Still in awe as I watched the east to west full motion these units provide. Like to see an upgraded option with thicker channel and heavier actuators with stainless bolts. I would be happy to pay double. These are awesome for off grid living
