Key Features

Innovative MPPT Design
  • Die-cast aluminium design ensuring excellent heat dissipation and Renogy Maximum Power Point Tracking technology with a high tracking efficiency of up to 99% and peak conversion efficiency of 98%. It is the best charging solution even in cloudy environments where the max power point of the solar panels will fluctuate all day.
12V/24V Automatically Detect
  • Automatically detects 12V or 24V DC system voltages, and the LCD screen and multiple LED indicators display the solar charging and battery operation information, customizable parameters, and error codes.
Full System Protection
  • Meant to safeguard your system, the self-diagnostic capability can assess and protect against reverse polarity, battery overcharging, battery over-discharging, overload, short-circuiting, and reverse current.
4-Stage Safely Charging
  • Features 4-stage charging (Bulk, Absorption, Float, and Equalization) of Lead Acid Batteries and 2-stage charging (Bulk and Absorption) for Lithiuim batteries as well as Lithium Reactivation.
Diverse Load Control
  • Connect DC appliances directly to the optional Load Terminals and monitor consumption or set up timer controls directly from the controller.
Remote Monitoring
  • RS232 communication port allows the Renogy Rover to communicate with the Renogy BT-1 Bluetooth module that will enable you to monitor the status and productivity of your panels through the Renogy DC Home App.

Warranty Information

Material and workmanship warranty 1 Year


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.

Rover Elite 40A MPPT Solar Charge Controller &amp; Remote

Clifford Friesen on May 12th 2022

This item failed within the first year and I was promised a replacement that never came and they are now, not answering my follow up emails. No explanation, no acknowledgement and not a replacement.

Very good product. Very solid and quality. I recommend

40A Rover

Alex on Mar 22nd 2022

I prefer using the 40 A rover because I set the voltages I want. User profile is always the in best way to go. I use lead acid. Can't vouch for the fancy lithium aspect of the controller.

40 amp controller

John Kent on Feb 15th 2022

This is the third one I have purchased. Haven't hooked this one up yet but am happy with both the first two. One Bluetooth module works all. I am using them both with 80 volt solar charging 24 volt battery. Getting better charge than old mppt regulator.

Rover 40 amp mppt controller

Russ Hrabchak on Feb 9th 2022

I am not technically advanced. This replaced my pwm controller. Plus I added three 100 w panels. Easy to install and monitor its output. I live a fairly north latitude and was immediately generating 42 watts and 12 amps plus. Very pleased.

Good unit

Shawn on Oct 9th 2021

I’ve only had the controller installed for about 3 weeks and So far, the unit has been increasing my power being delivered from my panels to the batteries. Very impressed.
