What To Know Before Buying RV Converter
RV converters are necessary for a more convenient RV life, but choosing one can be a little daunting because there are many features to consider. Before you make a purchase decision, here are things you need to know.
The different types of RV converters
RV power converters come in many types, so you must know them to find the best one that suits your needs.
- High output converter: If you run a high load of appliances, consider getting a high-output converter. This type delivers about 80-90 amps of DC output. 
- Deck mount converter: This type is the easiest to install. You can pick any place to install in your rig where your cords will reach. It’s perfect for customized rigs as you can install the unit under seats or anywhere else you desire. 
- Multi-stage converter: Also known as a smart converter, this type is a good RV converter upgrade if you own a single-stage converter. Unlike a single-stage model, a multi-stage unit has 3-4 charging stages to suit different battery states.
When your battery runs very low, it charges in a bulk or boost mode. It goes into the normal or absorption mode when the battery almost reaches a full charge. After the battery is full, it switches into a trickle charge. A fourth equalization stage is necessary to prolong battery life.
Benefits and drawbacks of RV converters
Many appliances in your RV run on DC power. They include gas leak detectors, light bulbs, and fans. To use home electricity for your camper, you’ll need an RV converter.
The top-rated RV converters transform the AC power from typical shore power or generator into DC power safely. They’re packed with many safety features to protect your electrical system. For instance, there are models with low line voltage protection to safeguard appliances from low voltage issues.
Also, a converter helps recharge your RV batteries. You need to keep them full to power your small devices when you go boondocking. If you choose a charger with smart features, you can prolong the life of your power units as well.
However, you’ll need to be mindful of the load capacity. If you overload the converter, you can blow a fuse. Also, some of these models have noisy built-in fans that may irritate you.
Features To Look For
RV converters are packed with features to work more efficiently. Here are some attributes that you should look for:
- Installation: You want to choose a converter that’s easy to install. Some models are pretty straightforward, so it’s easy to fit them in your rig. Check the instruction manual for the wiring connections and find an accessible location in your camper.
- Charging system: RV converter chargers work either in a single stage or multiple stages. The latter is preferable because it charges the batteries more quickly and efficiently.
The top-tier RV converter charger should also be compatible with many battery types, including your own. Besides, ones with a high battery capacity will be of great use.
- Safety features: Converters easily get hot under load and ambient temperatures, so try to look for an efficient cooling fan to dissipate the heat. Thermal protection also helps prevent overheating problems. You also want to protect the unit from reverse polarity and overloading to keep it from damage.
What is the Difference Between an RV Inverter and Converter
RV power converters and inverters both change your electrical supplies. The difference is their transformation.
An RV inverter turns the 12-volt DC power to 110 AC power. It’s used to run AC-powered appliances like TVs, motors, and radios.
Conversely, a converter transforms AC to DC power. It’s used to power a wide variety of electrical devices like water pumps, lights, and gas appliances.
How Big of a Converter Do I Need
To get the right size, determine the continuous power ratings of the appliances that you’re trying to operate in your RV. The converter’s rating should be high enough to manage all the loads when these appliances are working simultaneously.
The capacity of converters/chargers are measured in amps. To compute the total amps you need, divide the total wattage of all your DC-powered devices by volts.
Let’s say you get a total of 40 amps in power. You should look for a converter capable of handling more than 40 amps. In this case, a 45 amp RV converter is possible. Using a 30 amp RV power converter at this point will only trip the circuit breakers.
Will an RV Converter Work Without a Battery
Yes, a converter will still run without a battery. Just make sure that your RV is hooked to shore power. Also, read the manufacturer manual before doing it because there might be precautions to take.
Can I Use a Higher Amp Converter in My RV
It’s not recommended to use a higher amp converter in your camper. It should depend on your total load. Going more than five amps is okay, but going beyond that might cause potential problems like overheating the wiring.
For instance, it’s not wise to use a 50 amp RV converter when you only need 30 amps.
How Much Does It Cost to Replace an RV Converter
An RV power converter replacement costs around $150 to $1,600. Technically, a higher amperage means a higher price. For budget reasons, you should choose a model that’s enough to power all your devices.
How Do You Troubleshoot a WFCO 65 Amp Power Converter
It’s easy. Here are WFCO 65 amp power converter troubleshooting guides:
- Test the converter using a voltage meter to know whether it’s working. The meter should read around 12-13 volts.
- Conduct regular maintenance on your RV battery because the life of your converter depends on it.
- Check the cooling fan for any dirt or blockage. Clean the fan as necessary.
- Inspect the battery to see whether it is dead or not. This is especially important if you have stored the RV for a long time.
- Watch out for any blown fuses on the circuit board. Replacing the fuses is cheaper than buying a whole new converter unit.
If none of these troubleshooting tips work, perhaps it’s time to get a new converter.
The best RV converter can truly make your life safer and more convenient. Our top recommendation is the Powermax PM3 Series because it can run a good amount of 12-volt devices and charge any type of battery. I like its many safety features, like reverse polarity protection to help keep the unit safe from damage.
If you want to buy your own RV converter, you can follow our guide above. Make sure that the model’s capacity can handle all the loads you have in your RV. Moreover, choose a brand that you trust.
