rv converter charger wiring diagram

If you are looking for the best RV converter then take note that several choices will be laid out to you. This is the main reason why you have to conduct a thorough research about all the possible converters in the market that are suitable for use in recreational vehicles.

One important thing to take note of when searching for a good RV converter is its capacity. You have to ensure that you choose one with the proper and right capacity for your vehicle. Also, you have to remember that the higher its capacity, the heavier and larger it will be. A converter with a higher capacity also means a higher cost.

Your goal, therefore, is to look for a converter, which is capable of handling the wattage required by your appliances without being large and bulky unnecessarily. It should not be too heavy, as well.

Also, another thing that you have to remember is that the power level that your converter can handle plays a major role in ensuring that all your onboard electronics operate safely.

To guarantee your safety, ensure that you look for a converter capable of handling a minimum of 10 to 20 percent more than what your device with the highest wattage uses.

In case there are problems in your RV converter, then be aware that there are ways for you to troubleshoot it. In most cases, the whole RV converter troubleshooting process starts with determining what the actual problem is. The converter may fail to function because of a lack of power.

There are instances wherein you will face scenarios when the power supply is available but in insufficient amounts. Another problem that your RV converter might encounter is when the bad battery draws a charge from normal batteries. In this case, it would be best to examine the batteries individually.

This is helpful in determining whether they are completely charged. Also, you might need to use a multimeter as a means of inspecting the recharging ability of the batteries. This will let you know whether they tend to lose charge over time.

When it comes to troubleshooting RV electrical problems, especially the converter, the first thing that you have to do is also to figure out whether the power converter is indeed the component, which malfunctioned within the system.

Once you connect the power converter to the supply of power, check whether at the entry point, the voltage is within the 108 to 130-volt range. A reading within the mentioned range signifies that it is normal.  After that, check the actual voltage at the specific point where you connect the converter to the 12-volt DC box.

To determine if it functions normally, it should fall between the 11 to 13-volt range. You will instantly know if the converter malfunctions if the shown readings are below the mentioned range. Once you have checked the two points and ruled out the issue from there, checking out the separate components should come next.

Other Important Factors to Consider

What is an RV Converter?

An RV converter is a device that you can use if you wish to convert 110-volt household (AC) power into a 12-volt battery (DC) power then charge the batteries of your RV simultaneously. Each time you plug into an electricity or utilize a generator, the main job of the converter is usually to decrease 120-volt AC to 12-volt DC.

It performs such job as a means of providing more than enough power to all 12-volt accessories and appliances inside your vehicle. In case you do not plug into a source of electricity, the battery of your RV will provide power to all the mentioned accessories and appliances.

With the help of the converter, the risk of draining the batteries of your vehicle will be prevented. That is possible each time you plug into electricity or run the generator. Also, take note that the RV converter serves as the charger of the battery. It charges the batteries, thereby maintaining their power.

It would be ideal to look for a smart converter as it is an excellent upgrade regardless of the kind of RV you own. A smart converter charger often performs its charging function through four stages/cycles. The first one is bulk – the primary part of the cycle, which works in bringing the battery to close to the 90 percent charge.

The next cycle is absorption, which works in tapering the charge amp lower then slowly charging the battery’s last 10 to 20 percent prior to moving into the next cycle. The float is the next stage, which ensures that your RV batteries continue to be topped up at low volts.

Such is necessary for preventing the loss of electrolytes. The last stage is the equalize, which works in supercharging the voltage of the battery. The main purpose of this is to get rid of any accumulated sulfur that might fill the battery plates. Note that the buildup of sulfur in the plates might reduce the life of the battery and affect the charge quality.

How does it work?

A power converter is famous for being a valuable component in an electrical system of an RV. Note that in most cases, coaches and RVs come with two separate yet vital electrical systems. The first system supplies 120-volt AC power to high-watt and high-power appliances, including air conditioners, coffee makers, and hair dryers.

The second system is known to be a low-voltage part, supplying 12-volt DC to other items, such as lights, that do not require high current draws. Onboard batteries power these items sometimes, supplying power each time you are not hooked into a generator or outside source of power.

Your converter functions by changing 120-volt AC power into 12-volt DC each time you operate a generator or connect to the source of power in a campground. Such conversion is perfect for batteries and electrical systems with low voltage. The electricity provided by your RV converter can actually substitute the power provided by batteries.

One more thing that it can do is recharge the batteries. You can go for basic converters that work with just a single stage. You can often find this in low-priced and old coaches. However, if you prefer a converter with a more sophisticated internal circuitry then it would be more advisable to choose the more modern ones.

It is because the circuitry is sophisticated enough that it works in conditioning and charging the batteries properly. Some models of the converter can provide a fixed voltage, approximately 13.2 volts. These are not good choices because they have the tendency of preventing the batteries from getting a full charge.

They also tend to lessen their service life. If possible, go for modern converters with modern multi-stage circuits for charging. These include the four operation stages/cycles mentioned earlier – the bulk, absorption, float, and equalize.

Types of RV Converters

RV converters are available in different kinds with each one suiting the needs of a specific kind of user. To help you identify what specific type of converter you need, it is necessary to get to know more about them, including what each type can do.

Multistage converter – The multistage converter or charger usually involves an equalization procedure. This type is suitable for anyone who is looking for an effective solution when it comes to charging different kinds of batteries, including the lead-acid battery.

In the past, the only converter that you can use features a fixed voltage or simple single stage design. While they are still in use up to the present, it would be wise to look for a multistage converter. It is because it is compatible with the more advanced electrical systems today.

Note that these advanced electrical systems now use sensitive electronics and printed circuit boards. With that in mind, it is no longer surprising to see them needing a charging system, which is more comprehensive. That is what a multistage converter can provide.

In addition, it provides a clean DC voltage output and promotes fast charging. While using a multistage converter is quite complex, it is all worth it as it works in properly conditioning your RV’s batteries.

High-output converter – This type of converter is a great choice for those who are in need of one, which can meet the higher power demands of their electrical system. This means that the converter offers up to 80 to 90 amps to ensure that even the highest demands are met.

Extreme temperatures in some areas might also affect the batteries. It might have a negative effect on how the batteries discharge and charge. It can also affect longevity. You can lessen such risk by using a high-output converter.

Deck mount – As for the styles, one type of RV converter that you can choose is the deck mount. This is a unit, which you can screw to a sidewall or floor. You can actually install it anywhere provided you meet the ideal spacing requirements.

Some of the areas where you can install it are within a compartment or hatch, inside a cabinet, or under a seat. You can also install it in any other place that allows you to reroute the power supply.

Distribution panel – This is another style of RV converter that is available for anyone who loves to travel on the road. Many choose this style in case they need to replace a previously installed converter. It can be described as a large panel unit, which you can install in the RV’s cutout wall while staying easily accessible and visible.

This style also usually features the circuit breakers and fuses that are often behind the door or main panel. With such feature, you can conveniently access it in case there is a need for replacement or repairs.

Aside from the types and styles already mentioned, take note that there are also certain models that feature a battery charging circuit. This allows the charging of 12-volt house batteries while plugging the RV into shore power.

However, take note that even if the converter features a battery charger, you can’t still expect it to charge a fully dead battery.

Benefits of an RV Converter

There are many benefits that you can gain from installing the right one for your RV. A few of them are the following:

  • Ensures that your onboard appliances and fixtures run properly – Note that you need a properly functioning RV converter to ensure that all the electrical fixtures and appliances inside your vehicle run. It is mainly because it has the ability to distribute power all throughout your vehicle properly.
  • Prevents the risk of fully draining the house batteries – This benefit is made possible by converting incoming 120-volt AC into 12-volt DC power for your house system. Such conversion also takes place when you connect the RV to a generator or shore power.
  • Promotes the even distribution of power – What is good about an RV converter is that it allows the proper and even distribution of power to various AC and DC circuits found inside your vehicle. It does so by taking the primary power, which comes from the generator or shoreline then distributing it to various branch circuits. The distribution is made possible with the help of the individual switches of the breaker.
  • Charges house batteries – Another major benefit of having a converter inside your recreational vehicle is that it ensures that your house batteries stay fully charged each time you plug your vehicle into a shore power. It also promotes a full charge to the battery when the generator runs.

However, note that while the unit boasts of a battery charging system, it still has a quite low charging current available. In other words, it won’t be capable of properly charging house batteries with a low charge condition. Such a situation requires the use of a high-output and independent battery charger.

Troubleshooting your RV Converter

There are instances when your RV converter is unable to perform its intended function. In that case, you need to do some basic troubleshooting to get it to function again. When troubleshooting, you have to remember that the unit needs adequate voltage input in order for it to operate and function well.

Start by scrutinizing or examining the voltage found at the specific outlet where you plugged your RV. With the help of a handheld multi-meter, check the campground outlet’s voltage. The result should be around 108 to 130 volts but preferably, it should be 120 volts.

The next thing to do is to check whether a GFCI (ground fault circuit interrupter) protects the circuit. If that is the case then find out whether such interrupter is tripped. Another thing to check is the power that goes into the RV’s converter. Find out whether there are fuses inside.

It is necessary to replace any burned out fuses with the right replacements. The next thing to do is to listen. You will instantly know that your unit functions well if it hums. The next step is measuring the DC voltage. Such voltage is where the power is taken out from your converter to the DC breaker box.

You know that it operates properly if the voltage is around 12-14 volts. Anything lower than that indicates a malfunctioning RV converter. Another thing to remember is that RV converters feature a small fan with the main function of cooling the internal parts when the units are running.

Such cooling fan tends to turn on and off while you are using the converter. A temperature sensor also controls it. The cooling fan also operates at 120-volt AC. With that, be extra careful when you are still measuring the voltage. Make use of the AC meter scale as much as possible.

Also, ensure that the voltages get through the sensor to the motor of the cooling fan. If you notice that its motor runs excellently then it is an indication that you can jumper wire the sensor, making it possible to run the cooling fan.

Another thing that you can do is to upgrade into a multistage charger regardless of whether you will do it by adding new parts or replacing the entire unit. Doing such will greatly affect the performance of the battery. The good news is that there are several advanced and high-tech choices that you can find today.

With that in mind, finding one, which can meet the versatility and power required by your RV is possible. Make it a point to examine the RV converter on a regular basis, too. This will help you identify issues right away and fix them as soon as possible.

By learning these troubleshooting and maintenance tips, getting your converter to run for as long as possible will never become a problem. You can expect it to serve its intended purpose for a long time.

What is a power converter for in an RV?

The RV power converter is often used in providing power to vent fans, lights, thermostats, refrigerators, and any other onboard electronics. It is crucial to note that this power converter designed for your recreational vehicle is only needed in case you wish to charge your RV batteries after you plug them into a shore power.

It might also be needed if you use a generator. In case you are in a place with a lot of sun and you are using a solar power, then you can discard the use of the converter. However, since the weather is dynamic and changing in the majority of place, it would be best to have this installed in your vehicle.

How does an RV converter work?

The RV converter begins to work once you plug it into a source of electricity or power or when you are using an onboard generator. In this case, take note that the main job of the converter is to reduce the 120-volt AC to the 12-volt DC as a means of supplying power to all your onboard 12-volt appliances, facilities, and accessories.

In case you are not plugged into a source of electricity, then the battery in your recreational vehicle will supply power to all your 12-volt facilities and appliances inside the RV. If such is the scenario then the RV converter’s job is to prevent the battery from draining once you plugged in.

How to tell if an RV converter is bad?

There are actually a few signs that will help you instantly determine whether your RV converter is already malfunctioning or delivers a poor performance. Note, however, that in the majority of cases, you will know that your converter performs badly or is malfunctioning if it ceases to function.
