Looking for a part of a 2019 wiring diagram

[rferg800]

I am replacing original Gel batteries with a LFP battery.  This is just the start of a major boon docking upgrade. 

First 2 parts are:

1) Pecron F5000LFP This will upgrade our inverter to 7200 watt.  Battery capacity of 5120 watt hours at 48 volts. It has 2 solar charge controllers 3200watt each. Able to recharge with AC at 15amp or 30amp. It has a XT60 DC output port with adjustable voltage 12 - 40 volts which I will use to keep a 100 Amp Hour LFP 12 volt charged. 

2) Li Time 12.8V 100Ah slim Edition 

Both these new battery units are self heating and bluetooth accessible. Both of these will fit on the original slide out tray in the Oliver battery compartment. 

Plan is to disable the converter in the Oliver. Wire the new LFP 12v battery to a buss bar, which will also have the original Oliver Solar charge controller, the lead to the 12v side of the Oliver fuse box, and possibly the original 2000watt inverter connected. 

I plan to tap into the wire harness that goes to the shore power outlet on the curb side with a 30amp pig tail routed to the battery compartment. This I will be able to plug into the Pecron power station's 30amp receptacle.

I have 2019 (correction 2018🤪) hull 313. What drawing do you want?

None of the electrical schematics in my manual show either of the shore power outlets.

There is 8 or more different size wires leaving or going into the battery compartment on my Oliver. I need to id what they go to.

Heck I just realized that mine is a 2018 trailer. I apologize for my mistake. 

Anyway, does this help any?

thanks I will compare to my trailer tomorrow (Hull#466).

It's quite a different idea to build in what is designed as a portable power station!

I would suggest an inverter that is made to be built-in (like the Victron MP2), one that has terminals that can be hardwired vs. plugging in all your connections that may needed to be checked often after towing the trailer. It's also more expensive, this item and the plugs alone will cost 100s! It's certainly original, crazy IMHO, but at the same time, I would love to see your implementation. I've been through all this, and I'm very happy to help with wiring questions! 

Now to answer this question...

You will not find a wiring diagram to show all the wires to the battery bay. Bill noted, his wiring diagram does not even show the shore power connections to the EMS!

First thing I did was to empty the battery bay, disconnect all the wiring, and except for the two main B+ and B- cables, fish all the smaller wires back into the basement of the Oliver (see my before and after pictures of the battery bay). It makes a world of difference! I also removed the tray since it weighs 30 LBS and I wanted all the room to house 900 Ah of LiFePO4 batteries

The next picture (look bottom right) shows the 8 AWG wires that I removed from the battery bay. Basically you should find two red B+ wires. One of these connected to the 12VDC fuse panel and the other to the solar charger, plus the two corresponding B- wires to the ground bus. Additional lighter gauge wires will likely power a shunt or other. You just need to remove the wires, follow to the load and rewire internally. Your solar charger will be Zamp or something else, not the Blue Sky SC as shown in our 10-year-old hull.

I added 400A bus bars and removed all the breakers and fuses out from underneath the streetside bed. These are 8mm thick pure copper:

All of our switching is now under the rear dinette seat. Notice in this next picture, the breaker to the solar is moved forward as are all the cables shown in the picture above. The 3 jack fuses are also moved forward (the wires started there anyway).

There were some low power needs in the rear, so I took the light duty OEM bus, cut it in half to make it a +/- bus which is also fused under the dinette.

There are many things to think about in an extensive inverter/LiFePO4 upgrade! 😎
