- Innovative MPPT Design, up to 99% efficiency and Operate with Battery when Battery is 0 Volt: Renogy MPPT technology is 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. Even when the battery is dead (at 0 volt), the controller can activate it with small current and bring it to life.
- 12/24 Automatically Detect and Multiple Battery Adaptation: Capable with and automatically detects 12V or 24V DC system voltages. Perfect for Sealed Lead Acid, GEL, Flooded Battery. Especially design of user mode to let user custom Lithium Battery parameter manually to solve the common issue of voltage matching of lithium battery.
- 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 Lithium batteries as well as Lithium Reactivation. Intelligent charging method prolong your batterys life.
- Extremely Safe: Full system protection from program and insulated shell safeguards your solar system. The intelligent self-diagnostic capability can assess and protect against reverse polarity, battery overcharging, battery over-discharging, overload, short-circuiting, overheating, and reverse current. The UL certificated Rover charge controller with insulated shell prevents you from accident and keep your solar system in safe in high temperature.
- Easy to Understand and Set up: LCD screen and multiple LED indicators for displaying system operation information, customizable parameters, and error codes, you can understand the charging status and set the parameter better and easier with the display. Easy to mount design and mounting brackets are included for convenient set up. You can connect DC appliances directly to the load terminals, 5 load modes for better load management, make it easy for you to use your device.
- Comes with Bluetooth Module BT-2(Version 2) or BT-1(Version 1): You can monitor consumption or custom parameter directly from DC Home on your phone. RJ45 communication port allows the Renogy Rover controller to communicate with the Renogy BT-2 Bluetooth, which will enable you to monitor the status and productivity of your panels through the Renogy DC Home App.
- Mute and Excellent Heat Dissipation: Integrated heat sink, instead of cooling fan, provides a 0 dB surrounding for relax and ensures maximum charging efficiency and safety.

This controller installed easily, wire connections are secure, blue tooth module works very well allowing adjustment and viewing right on my phone through an app. No noise noticed from system, batteries seem to be getting the charge they need as it adjusts the voltage as needed. Load output very handy for nightlight operation

I’ve now installed 2 of these in 2 RVs. They have performed flawlessly that’s why I installed the 2nd one. I have it hooked to 2 Renogy 100w flexible panels powering a Battleborn battery in our teardrop camper. I run an inverter at night to power my Cpap machine. Bluetooth connection is so so. Like most BT connections in my world. I have a Renogy shunt monitor as well. I may be adding a folding solar setup for more input once at camp. If I do I will most likely be buying my 3rd Renogy charge controller.

I bought this to work with my upgrade from 200W of Solar (parallel wired) into a PWM 10A charge controller. NEW system was 300 Watts of Solar in series, and the 20A MPPT Rover charge controller. We get a lot of cloudy days this summer, a lot of rain, fog, it’s been a bit miserable. The old PWM system was losing ground due to insufficient solar output voltage to effectively charge the batteries. With the new Renogy Rover (and a third panel in series) my cloudy day solar voltage is still 60V+ into the charge controller, and my output to the batteries is good over a much wider range of light levels ! So - this MPPT thing - it works. I will be curious to see if the MPPT can still develop any battery charge when the next fog rolls in, that will be a good test, and I may update then. (*update* Cloudy foggy day and with three panels I was able to verify nearly 60V and good charge to batteries, far better than my prior PWM system). For now I am pleased with upgrading to MPPT and the higher open circuit voltage of a series solar array instead of a parallel PWM setup. Now —> the bad news is that the manual for the Renogy Rover Charge Controller is a bit lacking. The instructions are not quite always clear, and it took a few tries and a couple of YouTube videos on the product to sort out the configuration and operation of the interface. PROS: I like the Bluetooth and the App. (See pics). The app displays all that I want to see better than the little LCD screen on the controller. My wife, however wants nothing more than to see volts and amps on the LCD and is happy with that. I like that the controller is compatible with flooded, agm, Lithium etc batteries. You can also make a custom charging program/profile for your specific battery or preferences if you like. I set the Bluetooth dongle right next to the controller, and I can read state of charge from inside my truck, anywhere in the trailer, and up to about 40’ away from the trailer as well. Good range. CON(s): The manual is close, but not 100% yet. If they improve the system documentation they could make that 5th star easily.

I purchased the 20 Amp version on sale. It's real easy to setup and work with. The Bluetooth makes setup a breeze. Still waiting on a WiFi version :-). The Bluetooth did flake out on me once which required me to kill the power to everything and let it reset. In hindsight I should have purchased the 40 Amp. It never fails that you will want more panels and/or batteries if you have the space. The 20 Amp version limits you quite a bit if you plan to go 12 volt on the battery side. If you can do 24 volt then this is fine. With the price of good LifePO batteries I only had one so I couldn't go up to 24 volt (yet). I am using 4 100 Watt Renogy panels with two series pairs then wired in parallel which gives me a 24 volt input. My panels never get full sun on the entire array so I don't exceed the 20 amp limit when pushing 12 volt to the battery. If I ever get full sun to all four panels at once I would have a problem. (The image I uploaded only shows two of the panels since it was taken while I was installing them). I connected the device with 10AMG wire since that's about what it can handle with the screw inputs. I put a 20Amp fuse on the PV input side so I can kill the power to the panels whenever I need to work on anything on the battery size. This was needed quite a bit during setup. That should probably be a 25 Amp but, like I said, I never get close to 20Amps of input due to the trees around me. I used a 30 amp output breaker which is probably a bit large. It should be 25 Amps but 30 is what I had. Don't judge.
