Solar Project

Anyone familiar with how solar projects work?

I'm needing a charge controller, looking at this chart, I need atleast the 80 amp version to run my 30 amp air compressor, going off the load rating, am I correct?

One more question, where all would you put power switches and fuses? Very very rough system drawing below with the charge controller I currently have....

I had my 2 year old draw and write also

 

Can I just go straight from the batteries to the load? Skip the charge controller?

 

I see this is an older thread, you might already have the answers you need.

Before we start, to be clear, this is an automotive application right? In your truck? The charge controller you show looks like its more geared towards off-grid solar systems for houses or whatever.

From a high level (in automotive) the battery supplies the loads and also accepts charge from the charge controller. The CC and solar panels should be sized to compliment each other. The CC does not need to be sized for intermittent loads like a compressor. Im not really sure why they would show the DC load running through the charge controller, unless this is designed for offgrid like I said, in which case maybe the battery voltage is different?

Victron or RedArc are probably more aligned with the 12 VDC automotive world of solar
