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-2 Module and DC Home app you can view system performance in real-time and make parameter changes without having to get up!

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 (for Non-Lithium battery types), 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-2 Bluetooth module (NOT included in the package, highly recommend to add-on ) that will enable you to monitor the status and productivity of your panels through the Renogy DC Home App.
