Battery Fuse for Solar/Charger System
From the new solar/charger system was planning to run 6ga + and - wires right to the battery terminals, not tied in anywhere to the existing trailer wiring. Was thinking about using a Blue Sea 519...

I'm estimating max 10' run there and 10' back, but I haven't placed the MPPT or run the cables yet, so could be less. With 6ga wire the Voltage drop should be <2% for the MPPT currents.
The PD9260 will use the same wires, and its current could be higher, up to 60A I guess; it will have more voltage drop then. Will want the fuse to be 60A for it.
IMO, You are selling yourself and your batts short if you are running 6 ga more than a foot or 2 from your controller. Same with the converter. You can't compensate too much with your voltage setpoints as you will impact other appliances so might as well conserve as much voltage as you can. Go big or go home as some would say and 6 ga ain't big. At least 4 ga would have advantages, 2 ga more so. YMMV.
