Advanced Ultra Fast Maximum Power Point Tracking

Renogy Innovative MPPT technology with 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 System Voltage Automatic Identify

The Renogy Rover 20A MPPT Charge Controller supports both 12V and 24V systems and can automatically identify system voltage once connected to a Sealed, Gel, AGM, and Flooded battery (manual setting is required for 24V Lithium batteries).

Temperature Monitor and Compensation

Die-cast aluminium design ensures excellent heat dissipation. Fitted with a Remote Temperature Sensor, the Rover MPPT Charge Controller can measure battery temperature in real-time and use this data for very accurate temperature compensation, assuring stable and constant charging.

Intelligent Charging Protection

Renogy Rover MPPT provides 4-stage charging (Bulk, Absorption, Float, and Equalization) and features a comprehensive set of electronic protection functions such as stopping reverse current at night (from the battery back to the solar panel), automatic cut off to prevent over-charging and deep discharge, solar panel over voltage, over load, short circuit and reverse polarity protection.

Max. Solar Input Power 12V/260W, 24V/520W

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. 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.

Upgraded Energy Monitoring Experience

By adding the Renogy ONE M1 to your system, Wi-Fi connectivity uploads energy status to the data cloud in real time. Now you can monitor the system from Renogy ONE M1when you are at home, or through the DC Home app on your phone when you are out to explore.

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 20A MPPT charge controller have a built in 20A fuse for the rated 20A 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 20Amp charge controllers, we recommend using a 20Amp fuse.

5. If I have 2x200W panels which of these MPPT charge controller will be good? 20A or 30A ect.

If you connect these panels in series to a 24V system, the 20A model would be acceptable. But you would need a 30A controller if you connect these two solar panels in parallel to make a 12V system.

6. How many watts can Renogy Rover 20 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 260W for a 12V battery system or 520W 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.

7. 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.

8. What does 20A on MPPT charge controller mean?

20A represents the max amount of amps the controller can output going INTO THE BATTERIES.

9. 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.
