I want to build a small (1 panel) solar system for my car. The goal is to run a portable refrigerator. I am currently using a power station but while it has a built in MPPT controller that supports solar charging, it cannot charge and discharge at the same time. So here is what I think I need:
One 100W solar panel - most likely will go with Renogy at about $100 with brackets
PWM or another inexpensive controller - was looking at Renogy Wanderer 10A PWM controller
50Ah LiFePO4 battery - I have no idea which one to pick
Fuses - again, no idea what sizes and how many
Cables - gauge?
The refrigerator will be directly connected to the battery as it runs on 12V and will be the only thing that's powered by the system. When if runs, it draws about 46W. There is a built-in battery voltage monitor and can turn itself off when a certain low voltage is detected. There are 3 settings (high, medium, low) that correspond to certain voltage values (don't remember what they are off the top of my head).
There is a limitation of just one 100W panel as there is no space on the roof for more and I can fit only panel that's up to 42in x 22in. I would like to go with 50Ah battery because that's what I have in my power station and works fine. Even if I could squeeze 100Ah battery, I am not sure if one 100W panel would be able to charge it.
Could somebody help me out by checking if I am not missing anything? Also what battery would you recommend and what wire gauges and fuses should I use for this system? I am also open for recommendation on a different panel or solar controller if there is something better than the one I picked.
