Robust Charging. Serious Value.
Rover 20A MPPT Solar Charge Controller
Our panels are compatible with mainstream trackers. By leveraging optimal angles and open spaces, you can maximize solar energy generation and experience the peace of mind that comes with being self-sufficient.
Rest assured, you won't waste a single watt. Thanks to the high efficiency of bifacial panels, any excess energy generated by your solar panels can be stored in batteries for future use or sold back to the main power grid. Installing a solar roof is a wise financial decision that enhances the value of your home.
Cetified Protections
The Renogy Rover 20A Solar Charge Controlle features 8 electronic protections to actively monitor changes of voltage, current, and load for efficient and safe battery charging.
Bring Dead Batteries to Life
Activates dead batteries with small current to get it out of protection mode triggered by the battery management system (BMS).
Stay Cool, Stay Empowered
Made of robust die-cast aluminum, the heat sink that comes with the Rover 20A Solar Charge Controller allows the heat flow away through tubes to ensure maximum charging efficiency and safety of critical components.
Charging with Precision
The included external temperature sensor helps Rover 20A Solar Charge Controller track the battery's temperature all year round, avoiding under-charging in cold climates down to -40°F, and overcharging in blazing weather up to 149°F.
Control Your Energy From Distance
Versatile Load Control
Rover 20A Charge Controller features Auto-On/Off Mode, Timer Mode, Manual Mode, Test Mode, and Always-On Mode, further maximizing your system flexibility.
Package includes a Rover 20A Solar Charge Controller, a temperature sensor, several mounting brackets, and a user manual.
Wiring Steps
Do not insert the wires into the space below the socket/hatch, which will damage terminals because of loose connections.
Step 1
Complete a hole using a 55mm diameter punch and get all components of the device stand.
Step 2
With an embedded horizontal bubble, it's easy to achieve the horizontality of the device and avoid repeated leveling.
Step 3
Rotate, click clack, it's done.

1. In what order do I connect my system?

The off-grid solar system includes the solar panels, charge controller, batteries, inverter, Bluetooth module, and wirings. First, the battery should be hooked up to the charge controller with tray cables. Second, then connect your solar panel to your charge controller with adaptor kits.

2. What type of protection does the Rover MPPT Charge Controller have?

Battery Protection: Battery Over Discharge protection , Battery Over Voltage protection, Battery Reverse Polarity protection Load Protection: Load Overload protection, Load Short Circuit protection, Controller Overheating protection PV Protection: PV Over Current Protection , PV Short Circuit protection , PV Reverse Polarity protection, Battery overheating protection

3. What are the Positive ground and negative ground charge controllers?

In charge controllers, positive ground or negative ground refers to how the controller is wired internally. Positive ground means all the positives are hard-wired together, and the internal switching happens on the negatives. The negative ground is the opposite. It doesn't matter as long as your solar +/- runs to the charge controller and isn't grounded anywhere else.

4. Does the Rover 20A MPPT charge controller have a built in 20A fuse for the rated 20A load output?

No. Please always add an external fuse between the charge controller and batteries. To determine the fuse size needed between the charge controller and battery bank, you can match the amperage rating on the charge controller. For instance, if you have one of our 20Amp charge controllers, we recommend using a 20Amp fuse.

5. If I have 2x200W panels which of these MPPT charge controller will be good? 20A or 30A ect.

If you connect these panels in series to a 24V system, the 20A model would be acceptable. But you would need a 30A controller if you connect these two solar panels in parallel to make a 12V system.

6. How many watts can Renogy Rover 20 amp charge controller handle?

The Rover MPPT charge controller can work with standard off-grid 12/24V solar panels with high voltage or multiple panels with voltage up to 100V. And the maximum combined input solar power is 260W for a 12V battery system or 520W for a 24V system. In particular, this controller will significantly increase the efficiency of a solar system where the solar panel voltage is much higher than the battery voltage.

7. What is a Solar Charge Controller and what is MPPT?

The Charge Controller takes the power made by the solar panels and transform the ‘solar panel power’ into a form of power that the batteries can use. MPPT stands for Maximum Power Point Tracking, and it relates to the solar cell itself. Each solar cell has a point at which the current (I) and voltage (V) output from the cell result in the maximum power output of the cell. MPPT ensures that you get the most power possible from your solar panels at any point in time. It is particularly effective during low light level conditions.
8. What does 20A on MPPT charge controller mean?
20A represents the max amount of amps the controller can output going INTO THE BATTERIES.

9. What are the advantages of Renogy MPPT technology?

Renogy Rover series solar charge controller uses the most advanced Maximum Power Point Tracking (MPPT) technology to track solar panels' maximum power voltage point as it varies depending on sunlight exposure and temperature. This technology ensures the maximum efficiency of your solar system and significantly outperforms standard PWM solar controllers. Another benefit of MPPT technology is the wide solar input voltage range. This controller can work with standard off-grid 12/24V solar panels and with high voltage or multiple panels with voltage up to 100V.

    Renogy Power Controller with Bluetooth

    Posted by SOLABOY on Jul 13th 2023

    I purchased the 20AMP Renogy version with the bluetooth module. My ONLY problem with the module or in this case really its design is that the signal strength does not penetrate walls well.. so to be any real use (the 25-meter distance supported).. really is not lived up to. My window to outside mounted BT-1 might be 25feet max away, but it still has problems syncing up .. and normally I have to move to a room that has a window that is 10feet from the BT-1 .. rather exasperating . OTHERWISE the 'older' app connects and work pretty well .. thought still a bit archaic as apps go. I will give them great credit as I am using a tablet .. versus a cellphone .. and my tablet is NOT supported by the newest app.. so.. I guess I get what i deserve.. :-)

    Big improvement over our previous system

    Posted by Pat S. on Jul 24th 2022

    The product is working very well. It was difficult to select the battery type because the print on the screen is so small. Also, the directions were not clear regarding setting the load parameters. It took some trial and error to get it right.

    Dependable solar charger

    Posted by Desert Rat on Jul 5th 2022

    This has been running on my camper for over a month with a 230W solar panel. Keeps battery charged without overcharging. When I killed the battery overnight (<6V in the morning) it brought the battery back to life the next day, no issues. I specifically got this model since I plan on switching to Lithium batteries eventually and this controller will handle that transition with a few button pushes. Installation and setup was easy.

    Great charger

    Posted by DrHonHon on Mar 26th 2022

    It’s been 4 almost 5 months since Iv installed the unit on my truck. It’s been doing great charging 116ah of LTO. I bought the unit with the Bluetooth module but the Bluetooth has died on me. Iv unplugged it a few times. Power cycled the unit. It never came back. The charger it’s self is fantastic. I use it at shows to keep the alternator from melting down trying to support 27,000 watts. I can just shut down the truck and we’re all good. Keeps charging. Currently planning on getting 3-4 units for the camp to Keep all the vehicles out there topped off
