All three series are highly reliable, so you can be confident, no matter which series best suits your RV solar panel system.
How do you determine which Renogy MPPT charge controller best suits your needs?
There are only a few differences between the series, so we’ll FOCUS on those differences in the following sections.
System Battery Voltage
Most campers, RVs, and van conversions run with 12v batteries, with a smaller number running 24v systems.
If you run a 12v setup, the entire range is compatible.
For 24v systems, the Elite and Rover series are suitable.
For the few RVers running 36 or 48v systems, only the Rover series will suit.
The Renogy Rover and Elite series can connect to Bluetooth, but you must buy a separate Bluetooth module.
The Rover series uses the older BT-1 module, and the Elite needs the BT-2 module. These Bluetooth modules cost around 40 and are straightforward to set up.
Finally, there’s the Rego MPPT, which has Bluetooth built right in without additional accessories.
This makes installation much more straightforward than with the other two models.
Once connected to Bluetooth, all three charge controllers can be monitored via Renogy’s mobile app or the Renogy One.
With these features, users have greater control over their solar systems and can easily monitor their performance.
Renogy Rover, Renogy Elite, and Renogy Rego MPPT charge controllers are all excellent options when it comes to converting solar energy into usable electric energy.
The conversion efficiency of the Renogy Rover and the Rego series is 98%, and the Renogy Elite is 96%.
These values reflect how well each product can convert solar energy into usable electric energy and how this affects the overall performance of off-grid solar systems and RVers.
The Renogy Rego Rover MPPT series stand out due to their superior conversion efficiency of 98%.
That means more solar energy is converted into usable electric energy, producing higher output power for an off-grid solar system or RVer.
Only the Rover series offers a load terminal feature.
It comes with a 20A load terminal so you can plug a USB device directly into the controller, enabling it to charge straight from solar power instead of relying on the battery.
However, for RVers who spend most of their time traveling, this feature may not be as essential as it seems.
We never found ourselves using this feature in our five years of full-time travel.
Most RVers have access to other charging options, making the direct solar charging option less of a priority.
While the load terminal feature of the Renogy Rover is an exciting addition, it may not be crucial for RVers as we usually have more convenient charging points.
Max Input From Solar Panels
Each of Renogy’s MPPT charge controllers has a maximum amount of solar panels it can handle measured in watts.
We’ve listed the maximum watts the largest model in each series can handle.
The Renogy Elite is designed for smaller solar systems, supporting up to 520 watts at 12 volts. This makes it suitable for smaller setups or those with limited space for solar panels.
The Renogy Rover 100A can handle a considerably larger wattage, supporting up to 1300 watts at 12 volts.
That makes it ideal for more extensive solar systems or those looking to expand their solar capabilities in the future.
Lastly, the Renogy Rego offers a middle ground between the two, supporting up to 800 watts at 12 volts. This option caters to users who require a moderate solar system size that balances power generation and space requirements.
Regardless of which series you choose, ensure you read the model’s specifications to ensure it has the proper wattage input for your solar system.
Max Input Volts From Solar Panels
When comparing the max input volts from solar panels supported by the Renogy Rover, Renogy Elite, and Renogy Rego MPPT charge controllers, it’s essential to understand how this feature relates to your solar panel wiring configuration.
The way you wire your solar panels, either in series or parallel, will directly impact the voltage entering the charge controller.
The Renogy Rover 100A supports a maximum input voltage of 150V, making it suitable for most series solar panel configurations with up to about 6 or 7 panels.
The Renogy Elite 40A, on the other hand, supports a lower maximum input voltage of 100V. However, as it can only handle up to 520w of power, 100V is more than enough.
The Renogy Rego supports a maximum input voltage of 100V too. You must be careful here if you’re wiring your panels in series.
If you have 8 x 100w solar panels, their input voltage is around 20V each. So while the Rego could support 800w, it can’t support 8 x 20V (160V) input voltage. In this case, you’d need to install 4 x 200w panels which will likely result in less than 100v.
Check your solar panel specifications carefully.
There’s some difference between the series’ operating temperatures.
Both Rover and Elite series can handle temperatures as cold as.35°C /.31°F while the Rego needs to be a relatively toasty.25°C /.13°F.
At the other end of the scale, both Rego and Elite series’ can cope at 65℃ / 149°F while the Rover operates up to about 45℃ / 113°F.
All that said, it’s unlikely that the operating conditions will ever be that cold inside your camper (at least if you’re in there with it).
And there are many ways to keep your RV cool in summer, so neither you nor your charge controller cook.
Battery Charging Parameters
The Renogy Rover MPPT charge controller offers a unique feature that allows users to select a battery with custom parameters instead of being limited to regular lithium or lead-acid batteries.
By enabling custom parameters, the Renogy Rover ensures that the charge controller can efficiently and safely manage the charging process for various battery types, optimizing performance and extending battery life.
This feature is essential for any RVer utilizing a non-standard battery, as it ensures compatibility between the charge controller and the battery, preventing potential damage or inefficiencies caused by using incompatible components.
Battery Voltage Sensor
The Renogy Elite is compatible with the battery voltage sensor.
It’s a small cable that more accurately detects the battery’s voltage to improve the charging from the controller.
The Rego nor the Rover are compatible. However, charging profiles are probably superior to the Elite, and they don’t need it.
One notable feature that the Renogy Rego 60A MPPT charge controller lacks is an LCD, which could be considered a downside for some.
The absence of an integrated display may make it more challenging to monitor system performance and access essential information quickly.
However, the Renogy Rego compensates for this with Bluetooth connectivity, so you can access real-time data and system settings via your mobile device.
That makes the lack of an LCD arguably less critical.
When it comes to connecting cables, both the Renogy Elite and Renogy Rover use screw terminals, which can be a bit trickier to install compared to other types of connectors.
You might need pin crimps and extra care during installation to ensure everything is securely connected.
Remember that these screwed terminals could come loose over time because of vibrations or temperature changes, so you’ll want to check them now and then to keep your system running smoothly.
On the other hand, the Renogy Rego has these neat Anderson connectors that make installation a breeze.
They’re designed for fast and secure connections, so you won’t have to worry about them coming loose as much.
But there’s one thing to remember – you’ll need to buy compatible Anderson connector cables separately, which means an extra cost compared to the other models.
The price of these cables can vary based on their length and quality, so remember to consider this when comparing the overall costs of different charge controllers.
The Renogy Elite is the smallest and lightest among the three series, making it an excellent choice for those with limited space or prefer a more compact setup.
Its reduced size and weight can simplify the installation process and allow for easier integration into tight spaces, ensuring a seamless fit into your solar system without sacrificing performance.
The Renogy Rego, on the other hand, is almost a quarter smaller than the Rover 60A model, offering a more compact design while still maintaining its advanced features and capabilities.
This balanced approach between size and functionality makes the Rego attractive for those seeking versatility and space-saving benefits without compromising performance.
Lastly, the Renogy Rover 100A is the largest in the Renogy range, with its considerable size reflecting its higher capacity and more robust feature set.
While this massive solar charge controller may be suitable for larger solar systems, it’s essential to account for the additional space requirements when planning your installation to ensure a proper fit within your RV camper.
When comparing the costs of the Renogy Rover, Renogy Rego, and Renogy Elite solar charge controllers, it’s crucial to compare appropriate model sizes across the series to ensure a fair assessment.
The Renogy Elite series has two models priced similarly to their comparable models in the Renogy Rover series.
This similarity in price means you can FOCUS on the specific features and capabilities that best suit your solar system’s requirements, such as the smaller size of the Elite or the custom battery parameter support provided by the Rover.
When comparing the 60A models in the Renogy Rover and Renogy Rego series, the Rover 60A is typically around 100 cheaper than the Rego 60A.
This price difference may make the Rover 60A more appealing to those on a tighter budget or with smaller solar systems.
However, it’s essential to consider the additional features and capabilities of the Rego 60A, such as the ease of installation and extended warranty.
The Renogy Rego stands out with a generous 5-year warranty, providing extended peace of mind and protection for your investment.
This extended warranty coverage can be particularly appealing, as it ensures support and assistance from the manufacturer in case of any issues or defects within the warranty period.
In contrast, both the Renogy Rover and Renogy Elite solar charge controllers come with a standard 2-year warranty, offering a more limited duration of coverage compared to the Rego.
While this shorter warranty period may be sufficient, it is worth considering the potential benefits of the longer warranty offered by the Rego when making your decision.
Installing a Renogy MPPT solar charge controller in your RV or camper is relatively straightforward. Here’s a simplified step-by-step process:
- Determine the ideal location for the charge controller, ensuring it’s close to the battery bank and away from heat sources.
- Mount the charge controller to the wall using the provided mounting holes.
- Connect the battery cables to the charge controller’s battery terminals, taking care to match the positive and negative polarities.
- Connect the solar panel cables to the charge controller’s PV terminals, again paying attention to polarity.
- Connect the load cables to the charge controller’s load terminals if applicable.
- Turn on the charge controller and configure the settings using the LCD.
Always consult the user manual for detailed instructions, and consider hiring a professional if you need clarification on any part of the installation process.
Comparing The Most Popular Sizes

Renogy Rover Review
Unboxing First Impressions
Here’s a quick unboxing video of the Rover 40A.
Here’s what came in the box, in order of appearance:
- Product manual
- Warranty card and marketing materials
- Renogy Rover 40A charge controller
- Temperature sensor
- Mounting brackets
In addition to all the standard MPPT features, the Rover 40A has a screen, load terminals and ports for connecting the Renogy BT-1 Bluetooth Module (an additional purchase) and the included temperature sensor.
I took the Rover down to my basement to install it in a test system.
I used four screws to mount it to a wooden board I use as a mounting surface. Next, I connected a 12V LiFePO4 battery to the Rover and selected my battery type.
To select your battery type:
- Press the down arrow button until you get to the battery voltage screen
- Hold the right arrow button until the battery type selector starts flashing at the bottom of the screen
- Press the down arrow button to cycle through the options
- Once you’ve selected your battery type, hold the right arrow button to lock in your selection.
Here’s a video of the process:
Then I connected a 100 watt solar panel to start solar charging the battery.
The wire terminals are okay, but not my favorite. At first glance, they looked spacious and well-made. During installation, though, the screws felt loose. If I unscrewed them too much, it was hard to tighten them back down again.
It’s a minor gripe overall. And the wires never slipped out during use.
To pair the Rover 40A to your phone, you need to buy the Renogy BT-1 Bluetooth Module.
Once you do, you plug it into the Rover’s RS232 port. Then download the Renogy DC Home mobile app.
Note: There is an older version of the Renogy app called Renogy BT that you can still find on the app stores as of this writing. Do not download that version.
To pair your Rover to your phone using the app:
- Open the Renogy DC Home app
- Create an account or log in, if needed
- Tap the plus sign in the top right corner
- Tap “Add Devices” and wait for the app to search for your device
- Tap “Confirm” when the app finds your device. The app will take you back to the home screen and you’ll see the Rover appear in your list of devices.
- Tap on the Rover from your list of devices
- Browse your system’s specs on the screen that appears. You can see numbers like PV watts and battery charging voltage. At any point you can pull down to refresh for the latest numbers.
Here’s a video of the process:
You don’t pair it by going to your phone’s Bluetooth settings. It’s a different process than most Bluetooth devices.
Now you can monitor your solar power system from your phone. After pairing, mine told me my 100 watt solar panel was outputting a measly 2 watts — due to it being overcast at the time. It also showed my battery was sitting at around 13.1 volts.
You can also edit some system settings from the app, such as battery type, and view your energy production over time.
To select your battery type from the app:
- Open the Renogy DC Home app
- Click on your device
- Tap the 3 horizontal dots in the top right corner
- Tap “Settings”
- Tap the down arrow to the right of the Battery Type setting
- Select your battery type from the list of battery presets, or select “User” to create a custom charging profile
- Tap “Confirm” to lock in your selection
Here’s a video of the process:
As a simple test of the Rover’s Bluetooth range, I went to the second story of my house to see if my phone would still connect. I’d estimate I was 30-35 feet from the Rover, and the Bluetooth still connected just fine.
Charge controllers measure battery voltage, but oftentimes their measurements aren’t exact. The size and direction of the error can affect how good your controller is at charging your battery to the right levels.
So I checked the voltage accuracy of all the MPPTs I tested against a multimeter at the battery terminals.
The Rover placed fourth in this test with an average voltage discrepancy of 0.175 volts. Compare that to the Victron SmartSolar MPPT which placed first with an average of 0.075 volts.
I also used the Victron BMV-712 Battery Monitor to measure the max power output of all the MPPTs when connected to a 200-watt solar array.
The Rover tied for last in this test with a max output of 142 watts. The Victron SmartSolar MPPT again placed first with a max output of 146 watts.
A difference of 4 watts between first and last isn’t that big, especially considering the variables I couldn’t control — such as moment-to-moment fluctuations in solar irradiance and solar panel temperature. Changes in both of those affect solar panel output.
Note: These specs are for the model I tested, the Renogy Rover 40A. Renogy has a whole Rover product line with different charge current ratings, PV voltage limits and compatible battery voltages.
- Rated charge current: 40A
- Maximum PV open circuit voltage (Voc): 100V
- Battery voltage: 12/24V
- Battery types: LiFePO4, sealed (AGM), gel, flooded, custom
- Maximum PV input power: 520W @ 12V, 1040W @ 24V
- Maximum wire size: 8 AWG (10 mm2)
- Bluetooth monitoring: Yes (requires additional purchase)
- Temperature sensor: Yes (included)
- Power consumption: ≤100mA @ 12V, ≤58mA @ 24V
- Operating temperature:.35 to 45°C (-31 to 113°F)
What I Don’t Like
Who This Charge Controller Isn’t for
Renogy Rover vs Rover Elite
Despite its name, the Renogy Rover Elite is actually cheaper than the Renogy Rover. Beyond price, here are the main differences I noticed between them:
- The Rover has custom charging profiles. The Rover Elite does not.
- The Rover is compatible with the BT-1 Bluetooth Module, while the Rover Elite is compatible with the BT-2 Bluetooth Module.
- The Rover Elite is compatible with the Renogy Battery Voltage Sensor. The Rover 40A is not.
I recommend the Rover if you want to create custom charging profiles for your batteries, or if you already own the BT-1 Bluetooth Module. The Rover Elite is a good budget option if you only plan on using the battery presets.
The Bottom Line
After testing 5 of the best MPPT charge controllers on the market, I think the Renogy Rover offers the best bang for your buck.
It has all of the features that I want to see in an MPPT — compatibility with all the main types of solar batteries, custom charging profiles, optional Bluetooth monitoring and a good mobile app.
And, compared to other top MPPTs, the Rover gives you all those features for a pretty fair price.
