RV Wiring Diagram Basics

The RV wiring diagram describes all the electrical components and connections required to install a power source in your recreational system.

RV Wiring Power Sources

There are different power sources available to charge the RV and appliances. Some of the most common power sources include the following:

Shoreline (AC): RV typically draws power from the AC sources at 120V. However, it’s worth noting that 120V is the rounded estimate, and you may see some variations in shoreline power pedestals.

Generators (AC): The gas-guzzling generators can provide the same 120V AC power from a shoreline connection. However, the AC power source produces a lot of noise while working.

Solar Panels (DC): Many RV owners install solar panels, as these are eco-friendly and cost-efficient solutions to generate electricity. They can generate 12V of DC power to recharge RVs batteries or power stations.

Wind Generators: Wind generators are cheaper to set up than solar panels. However, you’ll have to deal with a bit of a complex implementation.

Engine’s Alternator: It is one of the ways to power an RV. However, alternators are less preferred compared to generators, especially those generators that work on solar energy.

Solar generators combine solar panels and a rechargeable power station. While solar power panels convert sunlight into electricity, the rechargeable battery stores it for later use. Jackery is one of the top solar brands manufacturing premium quality solar products. You can power most outdoor appliances in your RV using the powerful Jackery Solar Generator 3000 Pro.

RV AC Vs. DC Power

You can mainly power the RV with two electrical systems, AC and DC. AC, also called alternating current, supplies power to brick-and-mortar homes. It flows back and forth, making it a less stable powering solution.

That’s why we often use AC to DC converters to make the received power compatible with charging devices. Contrary to AC, DC is a more stable power source. However, one thing to note is that transmitting direct current over long distances is difficult.

RV Converter Vs. Inverter

The terms converter and inverter are used interchangeably, but they are different. The converter converts 120V AC power to 12V direct current.

On the contrary, the role of an inverter is to convert DC power in the RV’s battery bank to AC. This helps you to run appliances that require 120V AC power.

RV Wiring Diagram Components

Here is the list of essential components in a solar RV wiring diagram.

Solar Panels: Connected over the RV roof, these panels convert solar energy into electricity. There are portable solar panels available on the market that allow you to charge the battery without roof installation.

Charge Controller: The device controls electricity flow from solar panels to the battery bank.

Battery Bank: The device is responsible for storing power produced by the solar panels to charge the appliances.

Inverter: Its role is to convert DC to AC, which can then power different home or outdoor appliances.

Fuses & Connectors: These devices help connect the solar system components together.

Some optional parts required in the solar RV wiring diagram include:

  • Solar panel mounts
  • Solar panel extension cable
  • Battery Monitor
  • Alternator charging options like B2B charger or battery isolator

DIY RV Wiring Diagrams

The RV solar wiring diagram can be confusing, especially if you are trying it for the first time. Before you start the installation, you will need to understand the wiring color code, types of transfer switches, and required components.

RV Wiring Color Code

The RV wiring color code is the standardized set of colors that helps to identify different electrical wires in an RV. Learning the color codes will help you ensure electrical wiring is installed correctly.

2-Way & 3-Way Transfer Switches

An automatic transfer or changeover switch will help you connect all the components in your RV wiring.

2-Way Transfer Switches: These switches alter the power output between inverter or shoreline power, ensuring your RV gets the power supply.

3-Way Transfer Switches: The transfer switches change the power output between shoreline power, a generator, and an inverter (and battery bank) to supply the energy required by the RV.

RV Wiring Diagram FAQs

How many solar panels do I need for my RV?

Determining the number of solar panels will depend on how many electronic appliances you want to power with solar. For instance, 100 watts of panels can help you power small gadgets like smartphones, while you’ll need multiple solar panels and a rechargeable battery to charge other large appliances in your RV.

Jackery SolarSaga Solar Panels are built with advanced solar cells that make them highly efficient. You can combine the panels with a high-capacity Jackery Explorer Portable Power Station to charge multiple outdoor devices in your RV.

How does the wiring system work in an RV?

The large power cable connecting the RV to the shore power transmits nearly 120V power to the breaker panel of the vehicle. It then distributes the power to RV’s converter, allowing you to charge batteries and appliances. However, you can only access DC once you have unplugged your RV.

How to wire or install an RV solar system?

Here are some steps to wire or install an RV solar system.

  • Mount the solar panels to the RV roof in series or parallel.
  • Next, connect the charge controller to the RV battery bank.
  • You can connect wires from the solar panels to the charge controller using a circuit breaker.
  • Connect the battery bank and charge the controller.
  • Double-check the wiring and plug in the solar panels.
  • Seal the holes you might have created during the solar panel installation.
  • If you want to add an inverter to the solar system, connect it close to the battery bank.

Wiring or mounting the solar-powered RV involves multiple complex steps. But that’s not the case with Jackery Solar Generators. They are easy to set up and require no complicated wiring. You can connect solar panels to the power station to start charging your devices in minutes.

Final Thoughts

We hope the RV wiring diagram guide has helped you understand how to connect different components and install or mount the panels on the vehicle’s roof. However, finding proper parts, building connections, and permanently installing the panels can be overwhelming. That’s why investing in portable and flexible solar generators is highly preferred.

Jackery Solar Generators are ideal for RV owners wanting to power outdoor gadgets using solar energy. The ultimate power solution, Jackery Solar Generator 3000 Pro, can charge 99% of outdoor appliances for long hours. It has a built-in charge controller and inverter, so you don’t have to stress about installing them separately.
