Renogy 40A MPPT Solar Charge Controller with Bluetooth, Black

Innovative MPPT Design and High Efficiency

Renogy’s MPPT (Maximum Power Point Tracking) technology stands out with its exceptional efficiency, up to 99% overall and a peak conversion efficiency of 98%. This technology excels in cloudy environments where solar panel power points can fluctuate throughout the day. Notably, even when the battery is fully discharged (at 0 volts), the controller can revive it using minimal current.

Automatic Detection and Compatibility

This controller is compatible with both 12V and 24V DC systems, ensuring seamless operation with various types of batteries, including Sealed Lead Acid, GEL, and Flooded batteries. The user-friendly mode allows you to manually set lithium battery parameters, solving common issues related to voltage matching.

Smart 4-Stage and 2-Stage Charging Methods

For lead-acid batteries, it offers a 4-stage charging process (Bulk, Absorption, Float, and Equalization). For lithium batteries, it features a 2-stage charging (Bulk and Absorption), along with lithium reactivation. This intelligent charging method significantly prolongs your battery’s life.

Extraordinary Safety Measures

Equipped with full system protection, including program safeguards and an insulated shell, the controller ensures your solar system is safe. It features an intelligent self-diagnostic capability, protecting against reverse polarity, battery overcharging, battery over-discharging, overload, short-circuiting, overheating, and reverse current. The UL certified Rover charge controller maintains a zero decibel surrounding, enhancing both efficiency and safety.

User-Friendly Design and Setup

The LCD screen and multiple LED indicators display system operation information, customizable parameters, and error codes, making it easy to understand and manage the charging status. The design is easy to mount, and mounting brackets are included. Multiple load modes and direct DC appliance connection make using the device convenient.

Bluetooth Monitoring and Communication

Renogy Rover comes with a Bluetooth module (BT-2 or BT-1) that allows you to monitor consumption and custom parameters directly from your phone through the Renogy DC Home App. Additionally, an RJ45 communication port enables the controller to communicate with the Renogy BT-2 Bluetooth, providing comprehensive real-time status and productivity updates.

Silent and Efficient

Integrated heat sinks instead of cooling fans provide a silent operating environment, ensuring maximum charging efficiency and safety. With this setup, you can relax knowing your system is both silent and highly efficient.
