Van Electrical System Diagrams - Campervan Electric 12V/24V

In this video, I'm going to simplify van electrical systems for you, breaking down everything you need to know to get your campervan's electrical setup running smoothly.

I'll be covering key components in a van layout, a 1200W electrical system, a 3000W electrical system, and how long it takes to recharge the battery using solar, B2B, or shore charging.

Components of a Van Electrical System:
1. Power Generation: Learn about solar panels, alternators with DC to DC chargers, and shore power options.
2. Storage: Understand how batteries store power until you're ready to use it.
3. Consumption: Discover how to power AC and DC appliances like laptops, TVs, lights, and fans.

Campervan 12V Wiring Diagram: System 1
A medium-sized system with two solar panels, a DC to DC charger, and a 1200W inverter with a built-in 50A charger.

Details on wiring solar panels in series or parallel, connecting the battery with marine-rated fuses, and ensuring safe DC to DC charging from the starter battery.

Recommendations on cost-effective lithium batteries like the SOK or Litime over more expensive options.

How to wire the shore charger through an AC breaker box to power your camper's AC loads.

Campervan Electric: System 2
A larger 3kW inverter/charger system with a 24V battery setup to reduce costs and voltage drops.
Benefits of using 24V batteries over 12V, including cost savings on wires and charge controllers.
Detailed wiring instructions for DC to DC charging, battery balancing, and setting up shore power.

Recharging Times:
- Shore charging: 2.5 hours for a 24V 200Ah battery with a 2000W shore charger.
- DC to DC charging: 14 hours of driving at 360W.
- Solar charging: 2.5 days with an 800W solar panel array producing 2000Wh daily.

The diagrams are helpful as I know very little about this stuff. I would have liked to see the 24V system diagram, incorporate larger 24V batteries and/or four 24V batteries as anyone who wants to be able to run an AC for extended periods off grid would want to include a much greater capacity! Also, more info & diagrams discussing how a 48V system compares would have been useful!

Hello from South Carolina.
From minute 6.30 in this video, I can confirm. In my first build, I started with a 3500 watt Edecoa 12 volt. Mistakes were made😂. My battery combiner box has 5-100ah lithium batteries connected. When I did the math, my inverter draw potential is 292 amps maximum. I ended up using 350 Kc-Mil to feed my inverter.
It's a bit oversized, of course, but my equipment is in the attic. I had a fear of overheating the wiring. I will run this until the inverter dies and move to 48 volt on my next build. Between this channel and your book, I have learned more and have a way better comprehension. Solar is never boring. In fact it's addictive 😆
Stay blessed brother.

Video idea, should i put a fan on it?
How hot is safe, efficient and long term reliable.
I try keep everything under 40°C

I just received your book!! Thank you 🙏.

Of course, if you want to deal with even fewer amps, and thus much much less heat, you could just go straight to 48V. People put 48V + solar into golf-carts these days. I put together a tiny 48V system just last week for a friend. 2 x 75W solar panels, a cheap boost charge controller (since you only get ~40V from that little solar), a 25Ah 48V (51.2V LiFePO4) battery, and the cheapest 48V inverter/charger we could find. And that was mostly just to have a convenient AC charging functionality, otherwise I'd just have used a little 500VA or 800VA 48V Victron inverter.

Remember that power losses (and thus heat dissipation) goes by the square of the current. So a 24V system generates 1/4th the heat that a 12V system generates. But a 48V system generates 1/16th the heat that a 12V system generates (and 1/4th the heat that a 24V system generates).

Hi Nic what's your take on ac70 blueitti with 2 add on batteries for small offgrid cottage? All up $3, 500 usd. Thanks for the great content, I like going over your posts multiple times it cements the info lol.

Questtion on this MPPT controller. I hae 2 house to start batteries on my boat. Got to the boat and app said they were floating. Showed 20v from 2 100 watt panels 0 amps. When my boat is running my battery monitor shows -1.59 amp draw? Why? The voltage is 14.8 from motors. Shunt is installed correct to a neg bus bar. All house loads are off during readings. This also has a ACR

My van has 600ah of lithium.
So i can run the clothes dryer at night.

Please talk more about 120V/240V and hybrid systems that power the whole house instead of vidoes of small scale 12 volt batteries.

Thats dc power it dont pulsate or push far at all compared to ac.tesla made AC power.the.other electrical genius was eddison he was a believer in DC power with these huge dynamo's every so far usally 300 yards.
