2004 Safari 25 SS 400 Watt Solar Self Install

I have been searching blogs, posts, watching videos for several weeks in preparation for installing 400 watts on my 2004 Safari SS . I plan to install four 100 watt Renogy Monocrystalline panels on roof with combiner box and bring the #4 AWG wire either through the fridge vent or penetrate roof over closet next to refrigerator. My main questions are where to install the Victron 100/30 charge controller and BMV 712 Smart monitor and routing of the wires to the original battery box.
Any help, ideas, schematics, photographs, etc. would be greatly appreciated.
Thanks !

The charge controller should be as close to the battery as is reasonable, as the voltage loss between it and the battery has the greatest impact. In my case I have mine installed near where the DC junction boxes are for the 7-pin and fuse/bus bars between the battery and the internal wiring system.

The BMV display can be mounted anywhere you want to fish the wiring to, or you can just accept not looking at the physical display all that often and put it anywhere convenient. The tricky part of the BMV is you need to mount the shunt between *all* other connections to the negative side of the battery bank, so any cabling that leaves the battery connects to the load side of the shunt. The shunt isn't weatherproof, so that is something to consider as you map it out.

This was all relatively easy for my setup as my batteries are also now mounted under the bed of my 22FB right next to where all of this stuff lives. I am using the factory solar prep wire from the roof down to the charge controller, as I can't fit much solar on my small roof anyhow and have much larger wiring running to a connector on the A-frame for feeding in a solar suitcase.

Have you ruled out reusing the existing solar pre-wiring? You can install four 100W panels in a series/parallel arrangement with less than 2% voltage losses using the 10 AWG pre-wiring. I've done this along with several others on this site with great results.

No, I havent ruled out using existing prewire entirely but have already purchased the 4 awg wire. But I wll look at the prewire option. One end of prewire is in refrigerator compartment. Do you know where the other end terminates in 25' 04 Sleep Six ?
Thanks

Not sure this helps, but if not, perhaps someone with a 2004 Safari will shine in with the pre-wire locations.
