Question Schematic Rev 1 Review Please!

Hi fellow van nomads,


I've been knee deep in analysis over my electrical system for my van. Please take a look at the attached picture & let me know what needs to be changed! I've placed questions that I'm worried about in the same graphic. Positive criticism is needed! My main wickets to hit are:



1. More than enough power for two people.



2. Most up to date configuration on theory & parts.



3. Great quality parts & workmanship. Also, minimum # of parts/wiring without sacrificing safety & workmanship.



4. Shore power access & alternator b2b charger for emergencies.

Follow this link for the schematic!

Please increase the size or resolution of your drawing. (link is broken) (fixed link)
I can't make out the smaller text. PDF format would be great.
You probably want a shunt based battery monitor in the system.

All the best,
Hein

Jack.
Please supply a schematic circuit, so much easier to analyze. Eric.

Hein,

I added a PDF & larger screenshot image of it. Please let me know if it's any better.

What are the appliances you plan to run using the inverter? 3000 watts is a lot and requires close to 300A on the DC side. You would need 4/0 cables or larger for that. As mentioned, you need a battery monitor. The DC wiring is confusing so not sure how you have things connected. Next revision would be to add shunt & monitor and revise to make the DC side more readable. Probably want a master on/off switch on the DC side as well.

All the best,
Hein

First thing noticed: the "case ground" of your inverter/charger wants to go directly to the frame, not via the negative bus bar.
It's a safety thing ("earthing" any component failures inside the inv/chrg). Your shore power "third pin" wants to go to the frame, too.

I am amused by the thought of dual-chemistries and dual-voltages (24v AGM, 12v LiFePO4)
I assume your 180 amp alternator is a 2nd 24v alternator.

Since you're not using the Sprinter's native 12v system, you could isolate your entire LiFePO4-powered house system from the Sprinter's negative. The "ignition" switch input to the 24v charger could use a relay to separate it from the Sprinter ground, too.
You don't show the positive and negative feeds from your Alternator.

It's really better to have only *one* thread going for something like this ... and your other thread in "conversions" is the proper spot (since there's really nothing "NCV3"-ish about it).

It is very possible that I missed something, but where are you seeing 24v in his system?
