600 Watt Solar Roof Mount/Wire Plan

[yippie]

Hello all!

I’m now nearing that really fun, stress-free part of the build... solar and electriic I have been playing around with some layout plans and finally settled on this wiring configuration (see image). I was just inquiring to find out what the experts have to say as far as the efficacy of the layout. I appreciate the help ya’ll, what an amazing community! I’m 21 and my gf is 20 and we are both novices in pretty much every stage of the conversion process. So, if this layout is foolish please lmk in a magnanimous manner. (I’ve seen people get denigrated on this site with no constructive criticism )


Thanks!

Go down the list to 600w,400ah diagram, hope it helps.

Welcome Yippie,

With 3 or more parallel strings of panels you will want a combiner box with overcurrent protection for each string.

I was going to use a 40 amp inline fuse (6 awg wire) between panels and charge controller. Would that be suffice? Thanks for the response !

Each string needs it's own overcurrent protection. The fuse or breaker should be sized to protect the wire and panels. What are the ratings for your panels? Isc would be key here.

The short-circuit current is rated at 5.75 amps for each 100 watt panel. So I need two fuses for the two strings I got going? It's wired in parallel, just looks funny because it's an unorthodox layout for parallel config.
