An advanced charge controller that maximizes the performance of your solar system.
Powerful Heat Dissipation
Operates at peak performance even in extreme temperatures, ensuring your system is always running smoothly and efficiently.
Bring Dead Batteries to Life
Operates with 0 Volt batteries by sending small current to get them out of protection mode triggered by the battery management system (BMS).
Exceptional Resilience and Long-lasting Performance
Designed with materials and coatings that prevent rust and corrosion, ensuring your solar energy system is durable and reliable.
Maximize Your System Efficiency
The Rover 40A 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.
Prioritize Safety with Battery Voltage Setting
It is essential to set the battery voltage before connecting the Rover Charge Controller. This crucial step ensures enhanced safety and optimal performance.
Multiple Protections for Various Battery Types
Ensuring the utmost protection for your batteries, safeguarding against overcharging, over-discharging, short-circuiting, overloading, reverse polarity, and reverse current, and providing temperature compensation.
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 40A can accept up to 8AWG of wires.
Step 3
Tighten the screws to elevate the socket/hatch to complete the wiring.
Power Your Wild Adventures
Designed to excel in a variety of scenarios including RVs, yachts, cabins, and camping. Embrace the freedom of renewable energy wherever your adventures take you.

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.

    Good kit works well with the BT1 unit. Just use the correct wire and fuse gauge. No issues.

    I have just installed new lithium batteries and have the controller on the Lithium setting and it constantly shows the battery as 100%charged though the battery is only on 60%. I will try the user settings when I get hold of the correct settings and see if that makes a difference

    good value

    Posted by rita on May 18th 2023

    The last one worked 3 weeks then ruined my battery. This seems to be working better. It was supposed to be a replacement, but the first one was lost in the return. I would prefer better graphics, but, it works.

    Overall a great product that complements the Renogy range of batteries. Just one minor issue (not worth a 'star' deduction) is that the manual doesn't adequately explain how to access the charge level setting which is easy once you find out via Youtube!
