How Do RVs Get Power? A Quick Guide to RV Electricity
RVs get electricity from batteries, shore power, generators, and solar panels. Here''s how to use each source and avoid running out of electricity on your trip.
RVs typically utilize 30-amp or 50-amp shore power connections that determine how many appliances can run simultaneously. Always test power pedestals before connecting, and use surge protectors to safeguard your RV's electrical system. Knowledge is power, and that's especially true with your RV's electrical system.
Most RVs are set up so that if you have RV shore power (more about that later), you can run almost everything in the RV. If you don't have shore power, you run off the DC system, which can run the essentials like the lights and water pump for a few days.
Your RV can use two different types of electricity: 12-volt DC and 120-volt AC. Batteries store energy in the form of 12-volt DC or “direct current” power. Some devices and appliances can use DC power. However, many– especially larger appliances such as fridges and AC– require 120-volt AC or “alternating current” power.
Along with the RV power converter, many rigs also have an inverter, which turns DC power into AC power. RVs with an inverter will have specially marked wall outlets that run on the DC battery system but provide AC power. Most RVs are set up so that if you have RV shore power (more about that later), you can run almost everything in the RV.
