Hi, I'm just building my off grid system and I've been learning everything from scratch during the past few months. Someone shared this diagram (the first picture I attached) and it all seemed very simple and convenient so I'm planning to copy it. The other reason I want to copy it is that I get confused once I see bus bars and connections between the SCC and the inverter and I don't want to copy something I don't fully understand. These are two examples of builds I don't fully understand (the second and the third picture I attached).
My system is supposed to power a tiny home and I already bought 2x 485w solar panels, 100ah/24v lithium battery from Elkersolutions and Xunzel 24v 2000w inverter. I'll be adding the fuse block sometime in future.
There was no problem until I got to the issue of wires and fuses. People recommend T-class fuse on the battery because of the AIC. But as you can see on the diagram, I will have 3 lugs on the battery terminals. So my question is- Do I need to buy 3x T-class fuse in this scenario? If that's the case, I would probably be better off taking the time to understand the connections on the second and third picture.
Second question - Do I need to use a fuse holder with a T-class fuse, or it can be put directly on the battery terminal?
Third question - in the Wiring Unlimited book it says slow blow fuses are better when powering motors, compressors etc. I want to power one fridge with that inverter. The inverter has 4000w peak, but it doesn't say for how long. So is there a slow blow T-class fuse that should fit my application?
Thank you
Jan
