Maximize Your System Efficiency
The Rover Solar Charge Controller is the ultimate solution for both 12V and 24V systems, offering unparalleled versatility. It harnesses the maximum power from your solar panels, ensuring optimal charging efficiency.
Stay Cool, Stay Empowered
Made of robust die-cast aluminum, the heat sink that comes with the Rover 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 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.
Cetified Protections
The Rover Solar Charge Controller 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).
Wiring Steps
Do not insert the wires into the space below the socket/hatch, which will damage terminals because of loose connections.
Step 1
Loosen the screws above the terminals to make the socket/hatch descend.
Step 2
Insert the wires into the socket/hatch. The terminals on the Rover can accept up to 8AWG of wires.
Step 3
Tighten the screws to elevate the socket/hatch to complete the wiring.

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 40A MPPT charge controller have a built in 40A fuse for the rated 40A 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 40Amp charge controllers, we recommend using a 40Amp fuse.
5. How many watts can Renogy Rover 40 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 520W for a 12V battery system or 1040W 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.
6. 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.
7. What does 40A on MPPT charge controller mean?
40A represents the max amount of amps the controller can output going INTO THE BATTERIES.
8. 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.
