The unit was so simple and simple to set up to use, that I bought another Victron to use as one of the components of my "identical identical" solar array that I've put in my home to power my PC and television. (Yes the review is written using electricity from solar sources.)

It's insanely simple! My only complaint is that it's too little for me to deduct the star, but I would like to center it around the mobile app. (In my case, it's the Apple version.)

What to Look for When Buying a Solar Charge Controller for RV

Solar Regulator

Finding an RV solar charger isn't an easy task that requires more thought than one might think. A variety of essential factors be a major factor in choosing the right one to meet your requirements perfectly.

We'll look at these points below to make sure the consumer knows what the top solar charge controllers ought to appear like and provide. In the end, choosing the correct one will be an easier and easy task.

Charge Controller’s Amp Rating

One of the most important things to look at is the amp rating for each item. This factor is crucial since it will tell you the most amps available to your batteries. For instance, a person who has 100-watt solar panels that contain six amps of power would not require a charge controller that was 10 amps.

The result would be having an amperage requirement, that the charge controller would not be able to meet. So the two solar panels would produce 12 amps. The charge controller will only be able to use 10.

This can be an expense and isn't something an owner of a rig wants. I would suggest purchasing solar controllers that have an amp rating that is 25 percent higher than the solar panel's maximum power to prevent this issue.

The 25% wiggle space will allow you to prepare for the event that solar panels generate more energy than they are expected to produce. It happens far more often than most people imagine on their travels. It is important to have all the necessary tools to benefit from it. In addition, the additional 25% of the cost will allow you to install more solar panels down the way.

On/Off Button or Switch

Certain charge controllers don't include one of the best features which is an on/off switch. This may sound like a necessity in design but there are a few alternatives that aren't available. If you're like me, then I'd recommend avoiding these items like the plague.

The reason it is important is easy to comprehend. The on/off switch lets you turn off the device down without having to remove the battery's fuse. This feature makes the use of the device easy for the RV owner.

It is something that no one should ignore during the process. Make sure your selected RV solar charge controller comes with one before purchasing. It's not a choice anyone who owns a rig will regret.


Another aspect to take into consideration is the ability to adjust each product. In my opinion, it's best to ensure that the item you select includes a feature known as an adjustable voltage set point. This feature allows users to tweak the voltage throughout the process of charging the panel based on the type of battery used including gel, AGM, or lead-acid flooded.

Rig owners who are uncertain about the proper voltage to use should call the manufacturer to get more details regarding the battery. They will not have a problem providing the necessary information to make the right adjustment.

However, the addition of an adjustable voltage setpoint can make charging simpler and more efficient. All top-of-the-line options will probably come with this feature within the list of options.

Does It Have a Dry Camp/Shore Power Switch?

For any rig owner, it's smart to search for an option that has the power switch for dry camping or shore. It will allow you to alter the battery's charge setting point between standby mode and maximum power. This means you'll have the ability to increase the effectiveness of your charging process.

Owners of RVs should change to maximum power when they go far from the campground or RV park. In general, max power will be the ideal choice when you're away from an electrical source on the shore.

When you're working with shore power you're better off in standby mode. This option is also helpful when you want to store your gear for long periods, by keeping the batteries. With this information, it is clear how this option is essential for any top-of-the-line option.


Durability is a constant important role when buying products such as solar charge controllers. You'll want the one that can provide great results for years. Because of this, purchasers should consider what components went into the design of their model.

I would suggest you read the product's description as well as customer reviews of each product to evaluate their longevity. These materials should have all the information you require to determine whether or not the product will stand up to the long haul.

What About a Battery Temperature Sensor?

A majority of high-end charge controllers come with designs that include an electronic temperature sensor for the battery. What is this feature? It ensures that your batteries don't get under or overcharged, ensuring the highest efficiency.

Sensors for the temperature of your battery will do this information by looking at your battery's temperature and then altering the setpoint for charging accordingly. This ensures that any issues, like excessive loss of water or plate sulfation, do not show up.

Also, the battery temperature sensor can be a different feature that helps to ensure your batteries are in good shape. It's also a good idea to consider that this feature will help ensure that your batteries are always at a perfect charge level.


The price tag of each product will influence your final decision. Certain solar charge controllers are expensive, which is why having a well-planned budget is essential. It's important to think about what you're looking for from one and then determine a reasonable budget according to your needs.

For instance, a person who is looking to purchase an option that has an electronic temperature sensor for the battery is required to purchase an additional price. The budget you set should reflect this change to ensure that it's real. This tool will help make the whole process more manageable, by limiting your options.

It will be an easier time navigating through the various options. In the end, your budget will help you in selecting the best options that meet your requirements. This will lead to an easier purchasing process.

Which size of solar charger do I require?

Knowing the right size isn't as difficult as you think. It's quite simple. These chargers have ratings according to your solar array's current-voltage (push) and the solar system's current (amps).

The process is all about finding a charge controller capable of handling the volume of current and power generated from your vehicle's solar power system. This will typically result in three different voltage ratings that are 12, 24, and 48.

However, you may encounter charge controllers with ratings of voltage ranging between 6 to 60 volts. In addition, the amperage ratings on these devices may range between 1 to 60 amps. It sounds like a wide spectrum isn't it?

You can trust me; solving this problem isn't hard. For instance, if your system has the solar system you want to use with an output of 12 and an amperage of 14, you will require a controller that is at the very least 14 amps. However, there are additional things to take into consideration including sporadic higher current levels that occur, light reflection, and so on.

In this regard, you'll want to increase the amps by 25%. This will increase the amps that we require of our controller to 17.5 amps. Therefore you need to purchase a solar charge controller with a 20 amp rating(you'll have to round up the number of amps to 17.5).

It is important to note that a charger that has too high an amperage rating isn't going to be of any use. Experts generally recommend buying one that isn't utilizing many amps to take into account the possibility of adding additional solar panels shortly.

Can I use multiple RV solar charge controllers?

Answer to the question easily yes. You can utilize more than one RV solar charger since they all operate on the identical battery bank. Multiple of these devices is required when one charge controller cannot manage the load of your huge solar array.

The controllers will be connected via communication cables. This helps to prevent any problems. The wires would connect these charge controllers in a parallel fashion across the battery bank.



Now you have everything to make an informed and responsible decision about the best solar charge controllers for RV. From here it's an exercise to apply what you've learned to your research.

The process of finding the best one isn't difficult from there. However, if a query or two come up do not hesitate to ask me in our comments section. I'll be sure to respond to your query as fast as I can. Thanks for taking the time to read!
