![]() ![]() Luckily, replacing your converter is relatively easy. If you find you’re having issues with your RV’s 12-volt system, it might be due to a faulty converter. Without a converter in your RV, your battery bank will deplete, even when connected to shore power. Want lights in your RV? You need a converter! The 12-volt battery bank receives its charge from the converter converting 120-volt shore power to 12-volt. Lights, jacks, and fans function off your RV’s 12-volt system. Having a converter installed in your RV is a must, even if you plan to do all your RVing connected to shore power. This means a single 100Ah battery can charge at 5oA! Because of this using larger converters for lithium batteries will enable you to charge much faster. With lithium batteries however they can usually charge at a. If you have a 400Ah bank you can charge at 40A. 1C rate meaning a 100Ah battery will need 1oA to charge. ![]() Larger battery banks can draw more power to charge than smaller ones. You also need to size your converter based on your battery bank. The size of your RV power converter depends on how many amps you’ll be pulling from it. This allows you to consider which items you’ll be running at the same time. While looking at all of the electronics, note each device’s amperage rating. Generally larger RV’s need larger converters because they will have higher DC loads with more lights and appliances. If the converter’s output is exceeded additional power will be drawn from the battery.Ĭhoosing the correct size converter for your RV requires knowledge of how you use your RV’s electrical system. The more lights and appliances that are one the larger the load. The converter amperage draw will fluctuate depending on the loads applied. This is the DC amperage while the AC draw at max would be 540W/120 = 4.5 amps. A 45 amp converter will be able to output 45 amps of 12V DC current or 45×12 = 540 watts. RV converters are rated at what maximum DC amperage they can output. What Size Power Converter Do I Need for My RV? What Components Need To Be Changed When Switching To Lithium RV Batteries ? These are great all in one solutions for those that need an inverter for their RV along with upgraded charging functionality. They can convert 120 to 12 and 12 to 120. These boxes can basically send power both directions to and from batteries. Inverter charger units combine inverters and converters into one unit. Pro Tip: Learn more about RV electrical basics in our How are RV’s Wired Article What Is An Inverter Charger? Many individuals on social media use the terms interchangeably or incorrectly, making it even more confusing. Knowing the difference between an RV inverter and an RV converter can be confusing. ![]() If you’re planning to use electronics like hairdryers, microwaves, and coffee makers, you’ll need a larger inverter. You’ll now be able to watch TV and use other appliances that require 110-volt power. While a converter is a pretty standard piece of equipment in RVs, an inverter is not always installed.Īn RV inverter lets you use 110-volt electrical sockets from your batteries. However, an inverter will take 12-volt DC power and invert it into 120-volt AC power. What Is the Difference Between an RV Inverter and a Converter?Īn RV converter takes 120-volt AC power and converts it to 12-volt DC power for your RV. In addition to charging the batteries the converter powers all the DC needs of the RV when plugged in. Whether you’re connecting your RV to shore power or a generator, you need a converter to charge your battery bank. This process enables you to charge your RV’s 12-volt battery bank, which often powers fans, vents, and lights in your RV. Having an RV power converter installed in your RV allows your electrical system to convert 120-volt AC power to 12-volt DC power.
