So i have a larger problem where my Solar Mppt charger won't work with both solar panels if the battery voltage is to low, its only rated for 360w when using a 12v system. So thats why i haven't updated in a bit and have been putting the project on bit of a hold until i get some funds to acquire a 48 volt system for energy storage. I have been doing some other projects on the side such as assembling a mobile weather station instead.
Got my hands on a LFS105 12V 105Ah flooded batteri.
Now most parts have arrived. Still waiting on some things but now I have gotten my hands on the more important parts so I can start experimenting.
I did now though noticed that I have forgotten to buy some important parts for hooking it all up together. More specifically the MC4 Connectors for the solar panel and corresponding cable for it hehe. But no worries, I will just order some. While I'm at it I might order some more interesting sensors for a weather station and some other equipment for IoT.
The solar pannels are much bigger then one expects haha, I diden't have a banana for scale but i did have a tomato. But damn, isn't the panel beautiful, also got that sweet matt black finish on the sides!
Also bought some things for automation and controlling things.
Next thing to acquire is the components for the batteries, inspired by Martin Johnson - Off Grid Living. Now i'm just waiting on all my components to arrive. Will be working on some software in the meantime.
Here is a sketch of the system i was thinking initially with all the major components.
So after some research i decided on 2* 300w 24v solar panels. I also bought a Mppt solar charger from Victron energy. There is a lot of other version and prices, but this was the best and cheapest that fit my specs that i wanted with my budget.
So im getting the basics of solar tracking by using a Raspberry Pi and checking already open source projects available in the scope of the project. i was thinking of using a Odrive to control a motor. the idea is to following the sun in the most optimal angle, starting with one axes of movement.
