Hi! This is my first post on the forum, looking forward to interacting with y'all.
I'm currently designing a 24V LiFePO4 system for my van. It will be my first system. My question in this post is about the design of the DC loads.
So from my positive busbar will come my 24V DC line. From this line there will be three splits, one going to a 24V fuse box, one going to a 24/12 V DC buck converter, and one going to a 24/19 V DC Buck converter.
From the 24/12 line will be a 12V fuse box. From the 24/19 line will be just one load, my laptop. I plan to use my laptop quite a bit, and it's the only 19V load I have.
My questions are, how sound does this design sound to y'all out there? I'm concerned about the reliability of these buck converters, particularly the one to my laptop. Do I need extra overvoltage protection? Inrush current protection? I've heard the MPPT might see this circuit as a short on startup due to low resistance. I'd prefer to power my laptop via a DC step down instead of the inverter to reduce inefficiency.
