If there is one thing that separates RVing from traditional camping, it’s the comfort of electricity. Whether it is from a generator, solar panels, or RV hookups, electricity gives you the creature comforts that you get at home. It’s important that you know all the different electrical systems and what systems would be the most beneficial for your travels.
RV Electrical Systems 101
AC/DC Applications for RVing
RVs use both AC, alternating current, and DC, direct current, to power the components of your electrical system. The 12-volt DC system runs the electrical components of the engine and battery of your ride while the 120-volt AC system runs all the typical appliances and power outlets found on most RVs.
Shore Power and RV Site Hookups
Most RV grounds and parks offer electrical hookups known as shore power. Hookups often come in 20, 30, and 50 AMP outputs. The type of hookup depends on your RV, smaller RVs, pop up campers, and travel trailers often use 30 amps, while larger trailers and fifth wheels use 50 amps. Most sites have started to do away with 20 amp connections.
Shore power is usually AC current to power the appliances in your RV. It may be advisable to keep a 30 to 50 or 50 to 30 adapter with your RV in case your site doesn’t have the power supply your rig needs.
RV Inverters and Converters
In some situations, it may be necessary for you to convert or invert your power supply for a variety of purposes. To switch DC power to AC power, you will use an inverter.
The inverter can be helpful in situations where AC hookups are not available, of if you can’t, or don’t use a generator such as in a dry camping. Inverters come in various sizes depending on how many appliances or systems you need to power. While inverters are useful, they can be pricey.
RV converters don’t see as much use as inverters. A converter is used to convert AC into DC power for powering or charging small devices that are unable to handle the 120 volts of a standard alternating current outlet.
Converters are referred to as chargers. It’s important to choose a high quality and reliable converter that you can track to make sure it can handle the difficulties of an RV’s electrical system.
Solar Energy for RVs
Just a few years ago, solar systems were impractical for most RVers. The old systems were bulky, unreliable, and expensive. With the advent of new technologies, solar panels and electrical systems have become cheaper, more reliable, and customizable.
Solar panels are gaining popularity as an environmentally friendly option as they only use the sun’s energy to produce power without any nasty emissions or by-products as opposed to a gas generator. They are also popular among dry campers and those who wish to stay off the grid.
The panels convert solar energy into direct current power that can be used to power your RV’s electrical system. If you add an inverter to your solar system, you can power various appliances, too.
Some RVs are being built with solar panels preinstalled. For most people, though, solar kits are the easiest option available. These systems can be as small as a piece of paper to keep your battery charged up to integrated systems to meet the power needs of your entire rig.
Pro Tip: Consider alternatives to traditional RV electrical systems and the power they provide, such as RV deep cycle batteries and propane.
Now you can figure out which RV electrical components and systems best suit your RVing style.
