Hello everyone!
I just wanted to update you guys on what I've built for my solar system.
I choose a Sole UNI 5000 (5kVA MPPT hybrid charger+inverter), got myself 4 huge 12V batteries for free that were barely used in a backup power system (just about 50-100 cycles on them) and 6 310W poly panels. (DIAGRAM ->

For the tracking I've built a dual axis solar tracker from scratch (3D renders and concept photos HERE ->

I'm controlling it with a Arduino and ESP8266, I've added an anemometer, 4 quadrant light exposure sensor (made with LDR's), I control the actuators with relays (for now, I'm thinking of doing it with mosfets) and all the tubes and bars are huge overkill steal ones (cheaper and my actuators can handle it + probable expansion in the future).
All the work was done by me and my dad so all in all, the whole system cost us
LESS THAN 2800$!!!!And that includes every bolt, cable, MCU, sensor, the inverter, the panels,
EVERYTHING EXCEPT THE BATTERIES (THEY WERE FOR FREE). I've even multiplied the cost by 1.1 just to be sure in case I missed something.
I would love to hear your opinion about this project and if you can recommend any improvements
