Duncan - Unlike yours where you are modifying your existing batt location, I built an entirely new batt/inverter bay for the 6 AGM L16’s by eliminating the need for propane. Putz “helped” with that (see pic below) . Seems like yesterday Mike!

Have never needed to draw my 1260 Ah bank down below 70% SOC (that’s 378 Ah of use!). This should add to the pack lifespan. Although there’s a switch and I planned for it, have also never needed the extra Ah’s that combining the engine and coach banks would provide. Unless you are planning to run AC off all those panels, with only 4 L16’s you could easily get away with allot less solar watts. You probably know this but when planning off grid battery capacity and solar, Ah batt capacity should roughly match or be a little less than Solar watts on the roof. Too much solar and your Bulk charging stage won’t last long because your controller will go into Absorbtion. When that happens, the controller reduces its charging amps to keep battery voltage from going ballistic. You’ll then have allot of wasted solar output. With only 4 - L16’s, four 290W 60 cells would be overkill. One PT100 charge controller would also work well. I find the PT just about right for my 1260 Ah of batts. Plus cutting back on panels would streamline things up top and also keep your install costs down, a win-win.

Agree with Mike, VERY NICE. Keep those pictures coming. Putz and I only sleep at a Holiday Inn Express’s . Will be nice to see how a “real electrician” does it!

Cool Van, for the time being I have decided to say screw it to the panels.
Where I go quadding is either primitive campsites or has power.


We will see how it works this year, if it doesn't work as planned, then the panels will be going on.


Back at it today.


My original plan was to run 10/4 Tek cable from under the drawer in the bathroom behind the kitchen cabinets and down through a hole where bay water lines had been run....which have now been turfed as a bay fridge is much, much more important than a laundry facility


Got stymied by a plumbing vent so wound up going up and over with a couple of 10/2 NMD's.





Yes, that sloppy OEM wiring will be secured.











Angles cut and painted....powedercoat was an option but turn around time too long and I'm running out of time.









Cleaning up the rest of the old tray remnants:





Batteries going in to gauge width:





Mocking up the plate for the distribution:





All in:






1/2'' polyurethane for spacing between batteries:








Getting the underside of the eyebolts that will be used to secure the batteries down. Will be using a couple of turnbuckles to secure them.











Back to getting things drilled out etc:








To insulate the HSS I am using some thickwall heatshrink, HSS is 1'' x 2''.



















Plate drilled out and painted up:





Bus bars before and after tin plating, should slow the oxidation down:

Hopefully tomorrow I will have it mounted and wired:


4/0 on the right, 350 on the left. For those curious, 4/0 is about 212 mcm.





Busses to be covered:








All mounted and ready to go on the Bird:

I wanted 500 mcm but delivery was going to be too long to wait...mind you, if I had got on things sooner....lol.

Purchased 100’ of 4/0 for my project. Was way less $/ft purchased in bulk. When it arrived, couldn’t believe how heavy the spool was! Can’t imagine how much a spool of that 350 weighs. Like the shrink fit solid bars connecting busses and the switch. Definitely the pro way to go (though I’m not redoing mine ). While you’re fishing wires, you should do your roof solar run. Would save some time WHEN you go solar next year

Lol...if I did that now Van, you'd have nothing to razz me about later


In any case, pretty much buttoned up now. Fuel line will be redone/relocated this week.


Securing bar to hold the batteries down:








Lugs are sized for both regular electrical cable (rw90) or flex (welding cable). Manufacturers always suggest a size bigger for flex as it is much easier to get the fine strands in when the lug is larger...but a little patience and some black tape is the ticket. The tape holds the strands together for easy placement inside the lug barrel.






More progress:














Starter lug....had to poke the camera up to make sure the lug wasn't getting hung up on the plastic ribs of the start solenoid.






As this unit had the Pacs 1500 originally, there was no 120 outlet for it. This has now been rectified as it is fed with it's own 30 amp 120 volt supply. I also extended the wiring to run the beer fridge.








Said beer fridge in bay.





Pulling the wires:





Much neater and more practical:








Mounted the fridge down using angle iron and velcro....works very well, it's not going anywhere. Also ran a screw through the adjusting foot for good measure.















To power the fridge from the inverter, I simply used the same easy system that BB did for the inverter cct.






While I was underneath cleaning stuff up, I fixed up a few questionable connections:











Loom on the battery cabling:











Gee, I wonder if this would have caused issues sooner than later....
