How to Program a Solar Charge Controller
This blog post will teach you how to program a solar charge controller to deliver a proper charge profile to your battery bank. Now… What is a charge profile? Well, there are MANY different battery chemistries on the market. Lead Acid, AGM, and Lithium Iron Phosphate are three of the most common ones seen in camper electrical systems… and each one wants to be charged just a little differently.
One may want to be charged at 14.2V where the next one wants to be charged at 15.1V.
One battery may need a higher voltage charge when it’s cold when the next battery doesn’t care what temperature it is.
One battery may need to be charged slower the closer it is to full and the next battery may be able to be charged at a constant rate.
How to Program a Victron SmartSolar Charge Controller
The Victron SmartSolar charge controllers can be most easily programmed by using the VictronConnect app on any smartphone. Once the app is downloaded to your device and installed, make sure your bluetooth on your phone is turned on and navigate to the battery settings menu. Click on the charge controller that you would like to program.
Click on the cog icon in the upper right part of the screen:
Click the ‘Battery’ menu to access the battery settings menu.
And fill in the values as appropriate for the specific battery bank that you are programming the charge controller for. The example below is the recommended values for Battle Born LiFePO4 Batteries.
How to Find the Best Charging Settings for Your Batteries
Although there are general charging parameters recommended for the various chemistries of batteries, it’s always a good idea to get the recommended charging values for your batteries directly from the manufacturer of your batteries as the recommended charging values can vary depending on the brand. MOST battery manufacturers have their recommended charging values listed on their website or on the product info sheet, but if this is not available, you should email their customer support and ask them this:

Renogy Rover MPPT Charge Controller Review
Just so you know, this page contains affiliate links. If you make a purchase after clicking on one, at no extra cost to you I may earn a small commission.
This is my hands-on review of the Renogy Rover MPPT charge controller.
I spent weeks testing it on its own as well as alongside 4 of the best MPPT charge controllers on the market. I installed it in my basement, tested out its mobile app, and compared its voltage accuracy and max power output to the competition.
After all that, I think the Renogy Rover is the MPPT that offers the best bang for your buck. It works with the main types of solar batteries (including lithium), lets you create custom charging profiles, and — for an additional purchase — pairs with your phone via Bluetooth for remote monitoring.
And you get all those features for a good price.
A well-made and affordable MPPT charge controller
The Rover offers the best bang for your buck of all the MPPTs I tried. It’s best for 12V systems of 520 watts or less and 24V systems of 1040 watts or less.
|Rated charge current:
|Max. PV open circuit voltage (Voc):
|LiFePO4, sealed (AGM), gel, flooded, custom
|Max. PV input power:
|520W @ 12V, 1040W @ 24V
|Max. wire size:
|8 AWG (10 mm2)
|Yes (requires additional purchase)
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.
