What are my sources for electrical power when traveling in my RV?

Unless you're special ordering a manufactured motorhome or towable RV, the two bones sources of electricity in a manufactured RV will be shore power and business firm batteries which I volition explain below too as some alternative sources for power such as solar power and generators.

What is shore power?

Although this term is usually used when referencing boats or marine vessels when docked at a marina and plugging their electric organisation into the main grid used by the marina, the term is also used when referring to RVs being plugged into a main power grid supplied by a campground or an electrical circuit at someone's home or business organisation.

Nigh manufactured motorhomes and campers will have an electrical arrangement and long power cord that allows y'all to plug into shore power, although some older models may be missing this feature particularly if your RV was built before 1970. Should you lot be doing a custom build or restoration of an RV, installing a shore power can be very simple to more complicated depending upon how you want your power supply to operate and the number of items yous wish to power.

For example, you may have a small van that you lot accept converted to an RV and it is wired with 12v lights and fridge, but you want to add together a 110v line because y'all want to power a laptop computer, charge your camera batteries or scout some television. Adding ane or two outlets like this can be done easily past but installing a weather advisable inlet on the side of your van that is wired direct to those indoor outlets on a unmarried line. This works well for people that have a limited need of shore power and you only need a skilful outdoor 110v extension cord to run from the power box or outdoor outlet to your inlet.

However, the larger your RV, the greater your shore ability needs will exist too. More often than not, course A motorhomes are equipped with a l-amp power plug and course C may take either a fifty-amp or thirty-amp power plug. Class B motorhomes are commonly xxx-amp as are smaller campers. Recollect, the more bells and whistles you have on your RV determines the amount of amperage y'all will need.

Some other thing to keep in mind when RVing is that smaller and older campgrounds may not have the electrical outlets that your rig requires. It's non unusual to find many campgrounds are only supplied with thirty-amp outlets. To avoid this happening to you, I would recommend that you purchase an adapter that takes your 50-amp power supply down to a xxx-amp supply. The downside of this, however, is that you will need to be particularly mindful of the amount of electricity you are drawing at any given fourth dimension. When your system is designed to be running efficiently at fifty-amps and you lower the intake to a 30-amp draw while all the same trying to run as many appliances, electronics, and ac then it is likely you will blow a fuse or popular a billow.

What are house batteries?

Most RVs will accept at least one deep cycle bombardment that is used to supply power to 12v outlets and appliances such as frazzle fans, carbon monoxide detectors, RV style refrigerators, and some lighting. Usually, the bigger the RV, the more batteries yous are likely to have.

Go on in mind however, that things like an RV refrigerator can drain your bombardment or bombardment banking concern rather quickly so you demand to go on an eye on that ability consumption by checking your battery monitor often. Yous should likewise be mindful of the type of battery needed for your house RV battery and that it'south best to utilize a deep cycle battery that can handle heavy draws of power too as beingness constantly drained and charged which volition take a toll over time with cheaper batteries not designed for that blazon of use. Firm RV batteries can be charged by diverse sources merely are most often charged when you lot are plugged into shore power, while y'all are driving down the road past your engine components or a solar system. You lot can also employ a deep cycle bombardment charger to ability information technology upward.

What is a battery monitor?

Bombardment monitors are used to go along track of the amount of power coming into your RV and the amount yous are cartoon from your battery or battery banks at whatsoever given fourth dimension. Generally, the larger your trailer or motorhome, the more advanced your monitor will be. For example, yous may have solar panels that are adding power during the 24-hour interval and y'all may desire to periodically check the corporeality of power coming into your RV during these times. The same tin can exist said about usage during the nighttime when y'all are more than likely to exist drawing from your batteries instead of charging them.

Depending upon how many functions you need your battery bank to perform and access to the data when it is working, you can make up one's mind on the type of monitor y'all will demand. Manufactured RVs with house batteries will always take a battery monitor located inside and usually in the same proximity as your fuse boxes. However, if you are upgrading or designing your own electrical system you may need to supervene upon or determine the best monitor that works for you. As with near electronics these days, the complexities of these monitors vary any many of them tin even be accessed online or via cell phone applications when you are away from your rig.

What are alternative methods for supplying my RV with power?

Generators

Many grade A motorhomes and higher end campers such equally v^th wheels come with the option of including a generator when you lodge or purchase them. The advantages to having a generator that is installed on your RV from the manufacturer is that it is easily turned on by activating a switch inside your RV and that it is fueled by an onboard supply. By this I hateful that many class A motorhomes accept their generator designed to burn the same fuel as the engine requires and this eliminates the need to refuel them separately as you travel.

Another advantage to having a factory installed generator for your RV is that it will be installed in a well-insulated yet well ventilated surface area of your rig. It'south also likely to be quieter and less disturbing to those camping ground near you.

However, factory installed generators tin come with numerous disadvantages as well. Probably the major deterrent for most people is the added cost when they are initially exploring the idea of ordering and purchasing a new RV. These type of systems are very expensive and come with numerous added components that through travel and frequent motion, are probable to fail more than quickly than calculation an aftermarket generator to one of your storage bays and setting it up for employ outside and abroad from your RV as y'all boondock or visit dispersed camping sites with lilliputian or no power resources.

While I'thou not a huge fan of using gasoline or propane portable generators equally a long-term source of electrical power, they practise come in handy for short stays in an area where shore power is deficient or non-existent.

For brusque-term RVers and those looking to fish or chase in remote areas, I would recommend having a adept gasoline generator with yous that will run continuously for longer periods of fourth dimension on the fuel supplied to it. Personally, I have always had a portable generator that uses propane and while more expensive to initially purchase, the safe I feel I gained by not conveying around filled gasoline cans was far worth the extra toll. I also don't have any issues boarding a ferry gunkhole.

Call back, when choosing a generator, always consider the fuel needed to operate your system where you are traveling. At that place are places in the most northern parts of the American continent where there is no gasoline and propane tanks are the master source of fuel. On the other paw, there are several long stretches through United mexican states and many Central American countries where you won't find access to propane.

That said, generators are always a skillful option, but keep in mind that most of them are loud and gasoline or diesel generators produce frazzle that smells bad. No one wants to be in a beautiful location and heed to the drone of a fossil fuel fired generator a few hundred feet away or worse withal, right next door. In short, if you choose to use a generator, use information technology sparingly and respect the wildlife and those that may exist camped well-nigh you.

Solar power

Frankly, my preferred method of alternative power is solar based, and I am amazed past the amount of engineering science and economic theory that has come with this source of power over the last few decades. I grew up in an era where solar ability was just being developed. Its components were large, and it was cost prohibitive for nigh people that were interested in incorporating information technology into their lives.

Today, electronic components have become more advanced, solar cells are much smaller than when offset developed and the prices have dropped considerably since they were first developed. I beloved my solar electrical system and it literally has allowed me to stay in comfort at places where I couldn't have stayed merely 10-20 years ago. For a better understanding on how to install a solar electrical organization on your RV, delight take a look at my colleague Lindsey's article where she give you an splendid tutorial nearly installing solar power on her RV. Also have a look at our picks for the best RV solar panels.

I have an inverter and a converter in my electrical system. Are they the same thing?

No, a converter is used when y'all are hooked up to shore ability at a campground and it converts your 110 volt Air-conditioning power down to 12 volt DC ability to go on your house batteries fully charged. On the other manus, an inverter is used when you are non on shore ability and want to use 110v for something similar a coffee maker, microwave or television receiver and this inverts your power from 12v DC power to 110v Ac power. You can read my commodity on how to install an inverter for more info.

Proper setup for wiring, breakers, and fuses

As I said earlier, RV electrical systems can exist simple or complicated depending upon how y'all desire your system to perform. In this diagram you'll see that this is the well-nigh common RV electric set-upwards and the basic blazon most often installed past manufacturers.

Normally, when you plug your RV into shore power, the current flows to your 110v A/C breaker panel where information technology is then dispersed to your electrical outlets for plugging in small appliances, 110v lights or electronics. It also will transport current for some appliances such equally larger frazzle fans or water heaters that are hard wired directly.

The breaker console will also send a 110v electric current into the accuse converter that I explained earlier. Call up, the converter reduces that 110v to 12v where information technology is stored and recharges your house batteries. Once here, the 12v current will then supply electricity to a fuse box that works exactly as the larger breaker box that your shore power flows into initially. Smaller 12v light fixtures, your h2o pump, and some electronic power or chargers can also utilize your 12v ability supply as well equally some outdoor lighting and even your furnace fan motor.

You should also take annotation that in this schematic, they included a box that represents power being supplied to your business firm battery/batteries. This is the electric current existence supplied when you are not using shore ability only are instead driving down the road or even idling your motorhome engine. Well-nigh every motorhome has their engine's alternator designed to supply current to their house batteries, and many towable RVs are wired through their tow vehicle and camper connections that supply power to your camper'southward electric brakes and lights when driving while too recharging your house batteries.

Where should I put my power outlets?

Most often, this question will have no straight or specific reply. It'due south actually all about what you want the pattern of your RV to be. Merely put, where do you call up the power supply outlets should exist based upon your needs?

For example, if y'all have no reason to take an outlet side by side to your bathroom sink, then don't design one into your plan. Personally, I recommend having 2 110v outlets well-nigh your cooking and food storage area to supply 110v to a dual powered refrigerator also as supplying power to a coffee maker, microwave, toaster or any other item you lot may want to use when continued to shore power.

I would also make sure that I had an outlet or two wired to my living area and/or chamber, and then I could access my computer, watch my Television receiver or listen to some of my favorite music while traveling. That said, I would include 2-3 outdoor outlets on my RV to cover security lighting also as lighting for condom.

Pro tip: Working with electricity is dangerous. If you are unfamiliar with how electric systems are designed or are uncomfortable repairing and installing electric components, then it would be wise to contact a professional that is experienced with working on 12v and 110v wiring systems.
