Best RV Power Converter Buying Guide & FAQ
Knowledge is power, and this section below is going to help you learn more about these devices, their different types and how you can install your very own converter charger unit. We will also answer some of the frequently asked questions related to converters.
What to Consider When Choosing an RV Power Converter
- Output Size
Output matters a great deal when it comes to converters and this is measured in Watts. The amount of power you need to supply the appliances you own will most definitely dictate the size of the converter you need to purchase. If you install a small unit then you risk overloading it and this mistake can be avoided by simply calculating your wattage. This can be done by crunching wattage numbers and calculating the overall consumption of all RV appliances and adding an extra 15 percent for good measure. The resulting total is the answer to your converter size question.
- Overload Protection
Road safety is not just about wearing your seatbelt and following the rules. The quality of the devices installed within your recreational vehicle also matter. Purchasing a converter with safety features is money well spent. This includes overload protection that automatically shuts down the unit if too much current is flowing through the wires. Overload can result in fire and this is the last thing you need while traveling onboard your RV.
High powered appliances such as microwaves and irons require an equally powerful converter that can supply them with clean DC power on a regular basis. Therefore, you need to make a list of the appliances you have and proceed accordingly. Coffee makers and power tools have different needs compared to smaller non-heating appliances. This translates into a higher peak rating. You need to keep this in mind when shopping for efficient, high performance units that will supply you with enough power without breaking the bank.
Energy loss can cost you money in the long run and this is the last thing you need while embarking on your annual road trip. Heat waves in summer can force you to turn on the air conditioner, resulting in additional power consumption during your journey. The best RV converters will have energy efficient features to help you cut back on excessive power consumption. These units typically produce heat during the conversion process and purchasing the right unit will help curb this energy loss. It is important to note that RV converters tend to use up battery power even when they are disconnected from RV appliances, so it is recommended to switch it off rather than letting it consume more energy in your absence.
- Battery Power
Battery power is another important factor that you need to consider before making your purchase. You will need to make some simple calculations to determine the expected power consumption in Amps. Just divide the total power consumption in watts by ten and you will receive your answer. For example, if the total wattage amounts to 700 Watts, the expected battery power will be 60 Amps.
- Operating Time
The battery capacity dictates the operating time of an RV converter and this is measured in Amps per hour. You also need to consider the total wattage of the appliances found in your recreational vehicle. In order to calculate a rough estimate of this operating time, you will need to divide the battery’s Ah rating by the electric current needed by the converter in order to power all appliances at the same time.
Benefits of RV Power Converters
- Consistent Power Supply
Consistency and stability matter a great deal when it comes to powering your appliances. Laptops and television screens as well as air conditioners can be incredibly sensitive to current changes. Therefore, you need a reliable source of DC supply that will help preserve the quality of your appliances old and new. Even distribution of power is a quality you need in abundance when it comes to RV converters. This involves the DC and AC circuits installed inside your recreational vehicle. These units are basically in charge of sending out primary power from generators to the many branch circuits in a balanced manner.
- Battery Charging
Another advantage to having a charger converter unit while traveling is being able to charge your house batteries when needed. Spending your vacations on the road is not complete without your everyday use kitchen appliances. Adequate lighting especially at night is also a must and you need a charger in order to keep the RV running like clockwork.
Types of RV Converter Chargers
Not all RV owners have the same power consumption and vehicle size, which is why you will find different makes and models when it comes to RV converters. Knowing the difference between each one allows you to make an informed decision and makes the shopping process a lot easier.
- Multistage Converter
This type is ideal for RV owners who are searching for a unit that can charge different batteries including lead acid batteries. These converters are on step above old fixed voltage converters that had a single stage design. Now, you have a more advanced system that is more compatible with the equally state-of-the- art recreational vehicles of today. Moreover, multistage chargers are known for their clean DC voltage output and efficient charging time. Your RV batteries will definitely reap the benefits of having this unit installed.
- High Output Converter
This converter is ideal for RV owners who have a higher power consumption and who require a unit that will not crash and burn and leave you stranded without a converter somewhere along the highway. Durable high-power converters can deliver up to 80 – 90 amps to meet your increasing power demands while on the road. Using this type of converter can also come in handy during summer heat waves and in hot desert conditions since they can charge your batteries while preserving them at the same time.
- Deck Mount Converter
This unit can be easily mounted on a sidewall or wherever instructed. You can install deck mount converters inside the cabin and even under any of your RV seats. Just keep in mind that you need to mount it in a location where it is possible to reroute the power supply.
- Distribution Panel Converter
These converters are ideal for avid travelers whose factory unit is in dire need of an upgrade. This type can easily replace the old model and can also be installed in the exact same spot. Distribution panel converters have a sizable panel, are silent and reduce energy loss. They are also capable of charging batteries more efficiently compared to old noisy models.
How to Install a Power Converter in an RV
- First, make sure that your RV is not connected to the shore power. The cord must be removed from its outlet as well. RV owners who use generators must shut them off before the installation process begins.
- Disconnect the ground cable that belongs to the coach battery using a wrench from your toolbox.
- Convertors dissipate heat, so you need to choose a location that allows this to happen. Make sure that there is enough room for the cooling fan to operate as well. Mount your newly purchased unit via the side holes found in the flared panels or brackets.
- Follows the instructions concerning the electrical connection and keep in mind that the average converter has 4 terminals in total. Two are for the 110V wires coming from the shore power source and one for the coach battery hot wire and the final one is the terminal for a white 12V negative ground wire.
- Reestablish the negative connection belonging to the coach battery.
- Connect the RV cord to the shore power source.
- The final step involves testing the converter and this is done using a voltage meter. Use the meter to check the output across both the DC and ground wire terminals.
