Coach Electrical Systems

[neoneddy]

I have a 24v House and coach system, having the main engine and alternator as a backup power source and OTR power source makes so much sense.  Sounds like you know this.

I use 12v for all my LED lights, USB plugs, etc.   I started by just taking a wire from the middle of my 24v battery bank, but that lead to differences in charge for the 4  batteries.  I looked at getting an equalizer but it was a bit expensive. I do have one on the coach side still.

Anyway I bought this little DC DC converter for much cheaper to handle all my 12v needs.

Here is a video cued up to showing how I hooked it up.

Below is a link to view my power consumption.

I also run a normal 120v fridge, it doesn't use that much power honestly.   The fridge uses maybe 700w a day (it will cycle on  for 10-15 minutes every few hours).  Only other draws I have is a small computer, wifi router, stereo, tv, etc.   Every night I don't dip much below 80% state of charge.   Save the money on an RV fridge and get one from Home Depot or something.  I got my stainless steel fridge free from Craigslist, just needed the coils blown out with compressed air.

Thanks for the reply, I am a follower on your YouTube channel!  

I THINK I have one of those equalizer from Vanner, I dont know the specs on it though.  I know they converted my headlights to 12v, not sure what else.

I have that same one as well, but I figured I'd keep the coach side stock as much as possible.

I had considered pulling my house 12v from the Vanner, but didn't want to risk killing my coach starter batteries. 

My hope is to have the systems decoupled as much as possible , except for the charging while underway.

So you kept the headlights/coach, etc on the vanner and used the 2nd equalizer for the other house items?

You put all the electrical i the 3rd bay on the driver's side?  Where did you put your shore connections and all?
