Introduction
As an avid RV enthusiast, one of the questions I get asked often is whether RVs use AC or DC power. The short answer is both, but it can be a bit complicated. In this article, I will delve into the world of RV power systems and explain everything you need to know about RV power.
What is AC Power?
Alternating current (AC) is the type of electricity that comes out of a power outlet in your home or RV park pedestal. This means that the current flows in both directions, and the voltage changes polarity with time. Most household appliances and electronics run on AC power, which is why it''s the type of power we use in our homes.
What is DC Power?
Direct current (DC) is the type of electricity that flows in only one direction. This type of power is most commonly used in batteries, which store energy in the form of DC power. Most electronic devices such as cell phones and laptops also use DC power, which is why they have a charger with a DC output.
RV Power Systems
Now that we know what AC and DC power are, let''s talk about how they work together in RVs.
RVs have two main power systems - the 12V DC system and the 120V AC system.
The 12V DC system is powered by the RV''s battery, which is charged by the engine alternator or a converter when the RV is plugged into an external power source. This system is used to power the RV''s lights, fans, water pump, and other DC-powered appliances.
The 120V AC system is powered by the RV''s external power source, which can be a generator, shore power, or an inverter. This system is used to power the RV''s air conditioning, microwave, TV, and other AC-powered appliances.
Is RV 12V AC or DC?
Now, to answer the original question - is RV 12V AC or DC? The answer is DC. The 12V system in an RV is powered by a DC battery, and all the appliances connected to this system run on DC power.
However, some RVs have an onboard inverter that converts DC power to AC power, allowing the 12V system to power AC appliances such as TVs and microwaves. This means that some parts of the RV can use both AC and DC power, but the 12V system itself is DC.
Conclusion
In conclusion, RVs use both AC and DC power. The 12V system in an RV is powered by a DC battery, which is charged by the engine alternator or a converter when the RV is plugged into an external power source. The 120V AC system is powered by the RV''s external power source, which can be a generator, shore power, or an inverter. Some RVs have an onboard inverter that allows the 12V system to power AC appliances, but the 12V system itself is always DC.
Understanding RV power systems is vital for any RV enthusiast, as it ensures that you can power all your appliances and devices efficiently. Hopefully, this article has helped clear up any confusion you may have had about RV power and given you a better understanding of how it all works.
