Instruction: What is the best electrical system for RVs?

Response: There have been recent improvements in RV electrical systems. At the core, RVs run off “house batteries”, or large batteries that power the RV portion of the vehicle. There are several types of batteries available, and several ways of powering these batteries. The two main types of batteries are lead acid, and lithium. Lithium batteries are newer technology and will not be found in older RVs unless retrofitted. Lithium batteries have a larger charge capacity and can discharge safely further than lead acid batteries. However, lead acid batteries are cheaper. There are several ways of charging these batteries. The most common is a plug that provides either 30A or 50A of power, depending on the RV size. Most RVs also have generators, but generators are noisy and require either gas or diesel to run. Some RVs with lithium batteries (or more rarely, lead acid), have a second alternator installed that charges the batteries while driving. Finally, solar power is a popular option. Solar power is completely quiet and renewable, but can be expensive to install and is slower to charge batteries. Most RVs have a combination of the above, and consumers choose the system that best fits their lifestyle.
