I am working on installing a 24V system in a Cargo Van conversion. I still need to decide on Panels. Could someone please look at this from the MPPT down and offer any suggestions or corrections I should make.
I'm a beginner too, but what stand out to me is you need fuse & disconnect on the positive between battery and bus bar. Your Shunt should be on the negative side between battery and bus bar.
You don't need to fuse the MPPT line to the bus bar.
With 1 string of panels you don't need a fuse at all. If you choose to fuse it use a MC4 fuse.
You may want to switch to 48v to avoid 333amps and the larger wire and fuses.
If you already have parts you can't exchange I understand sticking with 24v. All wires 20% over max expected current. All wire the same. The mrbf should be 20% over max BMS output.
