Owing to of their complexity, many recreational vehicle owners obtain questions concerning the electrical systems of their vehicles and the exercise of accessories. These allow for what systems competency which accessories, when the accessories can be used, and what options are available to assemble further electricity for powering accessories.
System basics
RVs quality three leading electrical systems. The first is the 12-volt automotive DC system that is used to power the operation of the vehicle itself and draws its power from the battery located under the RV's hood. The remaining systems affect the coach portion or living quarters of the RV and are divided into a 12 volt DC system and a 120 volt AC system.
Coach DC system
Refrigerators for RVs are typically designed to feature two modes. The first is the gas powered mode, which runs on DC power and keeps the refrigerator cool while the RV is traveling. The second mode is the full-powered active electric mode during which ice can be made and the refrigerator light will come on. The electrical mode requires AC power.
Coach AC system
The coach AC system receives power from being plugged into a station at a campground or other location and is available only while the RV is plugged in. The AC system powers the electrical outlets and the secondary air conditioning system. Accessories that require outlets such as microwaves, coffee makers, hair dryers, televisions and toaster ovens all require the electricity of the AC system.
Refrigerators
The coach DC system is typically powered by converting AC voltage obtained while a RV is plugged into a charging station at a campground or other location. This can be stored and used while on the road. RV accessories that are typically powered through the DC system include items like the lighting, fans and stereos.
Generators
Some people choose to equip their RVs with generators to help power AC powered accessories while on the road. To determine the size generator required, it is necessary to add up the voltage of all the accessories that will be used simultaneously.
Considerations
RV batteries that power their electrical systems and accessories require cleaning and maintenance to work at peak performance. This can be done by the RV owner directly, but can be dangerous. Novices may wish to have these services performed by a professional at an RV dealership or service center.
