1. 【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.

2. 【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.

3. 【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. 【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.

5. 【Diverse Load Control】 Connect DC appliances directly to the optional Load Terminals and monitor consumption or set up timer controls directly from the controller.

6. 【Remote Monitoring】 RS485 communication port allows the Renogy Rover to communicate with the Renogy BT-2 Bluetooth module (highly recommend to add-on) that will enable you to monitor the status and productivity of your panels through the Renogy DC Home App/Renogy ONE.

20A Rover Solar Charge Controller

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.
