The Renogy 40A Rover MPPT Charge Controller is the most efficient type of charge controller. With up to 99% tracking efficiency, the Rover ensures maximum power point solar charging that gets more energy to your battery bank. Capable of automatically detecting 12V/24V lead acid battery systems, this crucial component is preset to also work with Gel, Flooded (wet cell), and Sealed batteries (manual setting is required for 24V Lithium battery). When paired with the Renogy BT-1 Module and DC Home app you can view system performance in real-time and make parameter changes without having to get up!
| PRODUCT HIGHLIGHTS |
| Monitoring with Renogy ONE Core |
Enhance your solar energy system with Renogy ONE Core for smart energy monitoring, providing intuitive visuals and real-time data. This 3-in-1 smart panel streamlines your energy management. |
| Innovative MPPT Design |
Crafted with a die-cast aluminum body for exceptional heat dissipation, the controller features Renogy's Maximum Power Point Tracking (MPPT) technology, achieving an impressive tracking efficiency of up to 99% and peak conversion efficiency of 98%. It excels as a charging solution, even in cloudy conditions where solar panel performance may vary throughout the day. |
| 12V/24V Automatically Detect |
Effortlessly identifies whether your system operates at 12V or 24V DC (for Non-Lithium battery types). The LCD screen and multiple LED indicators display essential information about solar charging, battery operation, customizable parameters, and error codes. |
| Full System Protection |
Designed to safeguard your system, the controller offers self-diagnostic capabilities to assess and protect against issues such as reverse polarity, battery overcharging, over-discharging, overload, short-circuiting, and reverse current. |
| 4-Stage Safely Charging |
Provides a 4-stage charging process (Bulk, Absorption, Float, and Equalization) for Lead Acid Batteries and a 2-stage charging process (Bulk and Absorption) for Lithium batteries, including Lithium Reactivation. |
| Diverse Load Control |
Connect DC appliances directly to the optional Load Terminals and monitor consumption or establish timer controls directly from the controller. |
| Remote Monitoring |
Utilize the RS232 communication port to enable communication between the Renogy Rover charge controller and the DC Home app and Renogy ONE M1 via the Renogy BT-1 Bluetooth module (highly recommended as an add-on). This feature allows you to conveniently monitor your panel's status and productivity on the go. |

How Should I Wire My Panels with an MPPT Charge Controller?
The panels can be wired either in series or parallel or a combination of series/parallel.
What Is the Max Wattage Input on the Rover 40?
The Renogy Rover 40A MPPT Solar Charge Controller can accept input of up to 520W for a 12V system, and up to 1040W for a 24V system.
Does the Rover 40A MPPT Charge Controller Have a Built-In 40A Fuse for the Rated 40A Load Output?
No. Please always add a fuse between the charge controller and batteries. To determine the fuse size, you can match it to the amperage rating of the charge controller. If you have one of our 40A charge controllers, we recommend using a 40A ANL fuse.
What Are the Advantages of Renogy MPPT Technology?
Renogy Rover Series solar charge controllers use Power Catcher MPPT algorithm to always ensure the charge controller converts most energy by locking to the most optimal maximum power point.
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.
What Is a Solar Charge Controller, and What Is MPPT?
The Charge Controller takes the power made by the solar panels and transforms 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.
What Does 40A on MPPT Charge Controller Mean?
40A represents the max amount of amps the controller can output going INTO THE BATTERIES.
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.
