Updated: Apr 16

Make off-the-grid living convenient and easy by installing an RV inverter. Here is a list of the best RV inverters you can invest in.


Best RV Inverters

Every RV road trip is an escape from daily life. But no matter how adventurous you are feeling, having no electricity in your RV will most definitely put a damper on your trip. That's where RV inverters come in. With their ability to transform DC power into the AC energy needed to operate appliances, RV inverters enable travelers to embrace the unplugged lifestyle while staying connected to the conveniences of home.


The market for RV inverters is growing, so you are not alone when it comes to being confused when buying one. But before you get to the purchase stage, it’s important to understand what RV inverters do and how you can choose the best fit for your RV. We have covered a guide for your entire RV inverter shopping experience below, from the research to bringing it home. So what are you waiting for, let’s get started!

 



How Do RV Inverters Work?

At the heart of RV power inverters lies the science of transforming direct current (DC) power into alternating current (AC) power. Your RV's battery system operates on DC power, the same type of energy that flows through your vehicle's electrical system. However, many of the appliances and gadgets we use in our daily lives, from laptops to coffee makers, rely on AC power. This is where the magic of inverters comes into play.


RV inverters act as electrical converters, transforming the DC power stored in your RV's batteries into the AC power required to fuel your electronic devices. Through a complex process of inversion, these devices oscillate the flow of electricity, mimicking the alternating pattern of household power. This transformation ensures that your RV becomes a portable powerhouse, capable of providing a seamless supply of energy to your appliances, no matter where your travels take you. Using RV inverters, you can seamlessly power your refrigerators, microwaves, and electronic devices, regardless of your remote location


What Size Inverter Do I Need For My RV? 

Determining the right size inverter for your RV is a crucial step to ensure a smooth and uninterrupted power supply on your adventures. The first factor to consider is your RV's battery bank capacity and type. The inverter needs to be matched to the energy storage capacity of your batteries. If you have a larger battery bank, you can support a higher-wattage inverter, providing more power for your devices and appliances.


Additionally, the type of batteries matters; for instance, lithium batteries often have a higher discharge capacity compared to traditional lead-acid batteries, allowing for a more efficient use of power. You can learn more about the differences between these batteries here!


Identifying your RV's biggest power draw is the next key consideration. Take stock of the appliances and gadgets you plan to power simultaneously. If your RV has power-hungry devices like air conditioners, microwaves, or coffee makers, you'll need an inverter with a higher wattage to handle the peak power demand. Calculating the total wattage of all your devices and selecting an inverter with a capacity that exceeds this sum ensures that you have a safety margin for unexpected power spikes and guarantees a reliable power supply without straining the inverter or your RV's electrical system. Finding the right balance between battery capacity, inverter size, and the power needs of your RV ensures you're well-equipped for any electrical demands on the road.



How Do I Install an Inverter in My RV? 

Installing an inverter in your RV can enhance your on-the-road experience by providing a reliable source of AC power for your electronic devices. If you are a beginner to your RV’s electrical system, here is a short guide to help you through the RV inverter selection and installation process. Be sure to double-check on the manufacturer’s manual too! 


  1. Assess Your Power Needs:

Begin by evaluating the power requirements of the appliances and devices you intend to run with the inverter. This step is crucial in determining the appropriate size and capacity of the inverter you'll need for your RV.

  1. Choose the Right Location:

Identify a suitable location for mounting the inverter. It should be close to the battery bank to minimize power loss through lengthy cables. Ensure the chosen spot allows for proper ventilation to dissipate any heat generated during operation.

  1. Disconnect the RV from Power Sources:

Before installing the RV inverter, disconnect your RV from any external power sources, including shore power and generator. Ensure the RV is not connected to AC power to guarantee a safe installation process.

  1. Connect to the Battery Bank:

Connect the inverter to the RV's battery bank using appropriately sized cables. Follow the manufacturer's guidelines for cable gauge and length to minimize power loss. Install a fuse or breaker box near the battery connection point to protect the inverter and the RV's electrical system.

  1. Grounding and Wiring:

Properly ground the inverter according to the manufacturer's instructions. Make sure that all wiring is secure, well-insulated, and routed away from potential sources of damage or interference. Use cable ties to organize and secure the wiring throughout the installation.

  1. Test the System:

After completing the installation, carefully test the system. Start by turning on the inverter and checking for any warning lights or indicators. Plug in various devices to ensure the inverter provides power as expected. If any issues arise, refer to the manufacturer's troubleshooting guide or seek professional assistance.

Troubleshooting RV Inverters 

Every electrical device is bound to trouble you at some point or the other. Here are some troubleshooting ideas when your RV inverter is not working or when you have RV inverter problems stopping you from powering your RV. Our top tips below will guide you through the process:


  • Check the Power Source:

Start by confirming the RV's power source. Ensure that the inverter is receiving power from the battery bank and that the batteries are adequately charged. Low battery voltage can lead to inverter shutdown or reduced performance.

  • Inspect Wiring Connections:

Examine all wiring connections from the battery bank to the inverter and from the inverter to the AC distribution panel. Loose or corroded connections can disrupt the flow of electricity. Tighten connections and clean terminals as needed.

  • Verify Grounding:

Proper grounding is essential for the safe and efficient operation of an inverter. Confirm that the inverter is correctly grounded according to the manufacturer's specifications. A poor ground connection can lead to malfunctions and safety issues.

  • Check for Overheating:

Inverters generate heat during operation, and overheating can lead to automatic shutdowns. Ensure that the inverter has proper ventilation, and check for any obstructions that may impede airflow. If the inverter is mounted in a confined space, consider installing a fan for additional cooling.

  • Review Error Codes and Indicators:

Most modern inverters for RVs are equipped with error codes or indicators to signal potential issues. Consult the inverter's manual to interpret these codes and troubleshoot accordingly. Common indicators include overloads, over-voltage, or under-voltage conditions.

  • Test with Different Appliances:

If certain appliances are not working, test the inverter on your RV with different devices to identify whether the issue is specific to certain loads. Some appliances, like power-hungry tools or devices with motors, may cause temporary overloads.

  • Check for External Interference:

Inverters can be sensitive to external interference, especially if improperly shielded. Radio frequency interference (RFI) from other electronic devices or poor-quality wiring can impact inverter performance. Minimize interference by keeping sensitive electronics away from the inverter and using high-quality wiring.
