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!
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.
The Renogy Rover 40A 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 battery）.
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.
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.
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.
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 M1 when you are at home, or through the DC Home app on your phone when you are out to explore.
